[0029] Hereinafter, the embodiments of the present invention will be described with reference to the drawings. However, the embodiments described below are subject to various technically preferable limitations for carrying out the present invention, but the technical scope of the present invention is not limited to the following embodiments and illustrated examples.

[0030] [1. Configuration of the seismic diagnostic device] The earthquake resistance diagnosis device 1 of this embodiment is a device that diagnoses the earthquake resistance of a building, such as a house, when the building is renovated. The earthquake resistance diagnosis device 1 is composed of, for example, a PC, a dedicated device, a terminal, and the like.

[0031] FIG. 1 is a diagram illustrating the configuration of a seismic resistance diagnosis device 1. As shown in FIG. The earthquake resistance diagnosis device 1 includes a control unit 11, a storage unit 12, a communication unit 13, a display unit 14, and an operation unit 15. The individual units included in the earthquake resistance diagnosis device 1 are electrically connected to each other via a bus or the like.

[0032] The control unit 11 includes a CPU, a RAM (Random Access Memory), a ROM (Read Only Memory), and the like. The ROM stores various programs executed by the CPU. The CPU reads out various programs stored in the ROM, loads them into the RAM, executes various processes in accordance with the loaded programs, and centrally controls the operations of each part in the seismic resistance diagnosis device 1.

[0033] The storage unit 12 is composed of a non-volatile memory, a hard disk, or the like. The storage unit 12 stores various programs executed by the control unit 11, various data required for executing the programs, etc. The various programs include, for example, a seismic resistance diagnosis program.

[0034] The storage unit 12 also stores a reinforcement method table 121. FIG. 2 shows an example of the reinforcement method table 121. As shown in FIG. The reinforcement method table 121 stores the wall standard strength for each reinforcement method used to reinforce the bearing walls of a building. The reinforcement methods are, for example, structural plywood (single-sided), single brace, double brace, etc., but are not limited to the examples shown in Fig. 2. The wall standard strength is a numerical value that indicates the strength of a wall. The reinforcement method table 121 also stores the reinforcement cost per meter of wall length (width) for each reinforcement method. The reinforcement method table 121 stores, as the reinforcement cost, the reinforcement cost when reinforcing an existing bearing wall and the reinforcement cost when adding a new bearing wall.

[0035] The communication unit 13 is composed of a communication module and the like. The communication unit 13 transmits and receives various signals and various data to and from other devices connected by wire or wirelessly via a communication network.

[0036] The display unit 14 is configured with an LCD (Liquid Crystal Display), an EL (Electro Luminescence) display, etc. The display unit 14 performs various displays according to display information instructed by the CPU 11.

[0037] The operation unit 15 has a key input unit such as a keyboard and a pointing device such as a mouse. The operation unit 15 accepts key operation input and position operation input from the user, and outputs the operation information to the CPU 11. The CPU 11 accepts the input operation of the user based on the information transmitted from the operation unit 15.

[0038] [2. Operation of the seismic diagnostic device] Next, the operation of the earthquake resistance diagnosis device 1 will be described. The control unit 11 of the earthquake resistance diagnosis device 1 executes the earthquake resistance diagnosis process shown in FIG. 3 to diagnose the earthquake resistance of the first floor of a multi-story building or a single-story building.

[0039] The control unit 11 performs earthquake resistance diagnosis processing to diagnose the earthquake resistance of, for example, a wooden frame house that was newly built before May 2000. This is because, due to the revision of the Building Standards Act related to earthquake resistance in June 2000, houses newly built before May 2000 may have weaker earthquake resistance than houses newly built after June 2000.

[0040] (Earthquake resistance diagnostic processing) First, the control unit 11 accepts an input operation of building information by a user via the operation unit 15. That is, the control unit 11 acquires the building information (step S1). The building information is information about a building, and includes the number of floors of the building, when it was newly built, the type of roofing material, the width of the short side of the building, the type of foundation, and the deterioration state of the foundation.

[0041] In step S1, the control unit 11 displays an input screen 141 shown in FIG. The control unit 11 accepts selection of the building floor number from preset options in a floor number field 141a in the input screen 141 using a pull-down menu. Options for the number of floors of a building include, for example, "two stories" or "single story."

[0042] Furthermore, the control unit 11 accepts selection of the construction date of the building from preset options in a construction date field 141b in the input screen 141 using a pull-down menu. The options for when the building was built are, for example, "Before May 1981" or "After June 1981." This is because the Building Standards Act was revised in June 1981, and the earthquake resistance standards for homes built after June 1981 (new earthquake resistance standards) differ from those for homes built before May 1981 (old earthquake resistance standards). The options for the construction date of the building may be set in more detail.

[0043] Furthermore, the control unit 11 accepts a selection of the type of roof covering material for the building from preset options in a roof covering material field 141c on the input screen 141 using a pull-down menu. Options for the type of roofing material for a building include, for example, "iron sheet," "slate," "tile," "earthen tile," and the like. Buildings with "iron plate" or "slate" roofing materials are classified as "light buildings" in terms of weight. Buildings with "tile" roofing materials are classified as "heavy buildings" in terms of weight. Buildings with "earthen tiles" roofing materials are classified as "very heavy buildings" in terms of weight.

[0044] Furthermore, the control unit 11 accepts selection of the width of the short side of the building in a field 141d of the width of the short side of the building from preset options in a pull-down manner in the input screen 141. Options for the width of the short side of the building are, for example, "less than 4m" or "4m or more." The shape surcharge coefficient is set based on the width of the short side of the building. Specifically, if the width of the short side of the building is "less than 4m", the shape surcharge coefficient is "1.13", and if the width of the short side of the building is "4m or more", the shape surcharge coefficient is "1.0".

[0045] Furthermore, the control unit 11 accepts selection of the type of foundation of the building in a foundation type field 141e in the input screen 141 using a pull-down menu from among preset options. The options for the type of foundation for a building are, for example, "Spread foundation / raft foundation" and "Other (block foundation, etc.)". "Other (block foundation, etc.)" generally has lower earthquake resistance than "Spread foundation / raft foundation". The strength reduction factor for foundation specifications is set based on the type of foundation of the building.

[0046] Furthermore, the control unit 11 accepts selection of the deterioration state of the building's foundation from among preset options in a foundation deterioration state field 141f on the input screen 141 using a pull-down menu. The options for the deterioration state of the building foundation are, for example, "no cracks or chips", "cracks or chips present", "unknown", etc. The strength reduction coefficient according to the foundation specifications is set based on the deterioration state of the building's foundation.

[0047] Note that the control unit 11 may accept a manual input operation of the building information by the user via the operation unit 15 in step S1.

[0048] Next, the control unit 11 determines a part of the building specifications based on the building information acquired in step S1 (step S2). For example, the control unit 11 determines the specifications of the column head-column base joint of the building based on the construction date of the building selected in step S1. Furthermore, the control unit 11 determines whether or not the building has foundation rebars based on the construction date of the building selected in step S1. For example, if "before May 1981" is selected as the construction date of the building in step S1, the control unit 11 determines that the building has foundation rebars "not present." On the other hand, if "after June 1981" is selected as the construction date of the building in step S1, the control unit 11 determines that the building has foundation rebars "present." Furthermore, if the building is multi-story, the control unit 11 determines the specifications of the second floor of the building based on the construction date of the building selected in step S1. On the other hand, if the building is a single-story building, the control unit 11 determines the specifications of the shed or roof of the building based on the construction date of the building selected in step S1.

[0049] Next, the control unit 11 accepts an input operation of a floor plan of the first floor of the building by the user via the operation unit 15. That is, the control unit 11 acquires the floor plan of the first floor of the building, which is design information of the building (step S3). The design information of a building is not limited to a floor plan of the first floor of the building. The design information of a building is information showing a design plan of the building, and includes floor area information of each part of the building, wall length (width) information, etc. The design information of a building may be, for example, a list in which the floor area and wall length of each part of the building are described.

[0050] As described above, in steps S1 and S3, the control unit 11 acquires building information related to the building and design information of the building. The control unit 11 functions as an acquisition unit.

[0051] Next, the control unit 11 extracts the load-bearing walls of the building from the floor plan of the first floor of the building acquired in step S3 (step S4). The load-bearing walls are, for example, walls with a width of 90 cm or more and no openings. Figures 5 and 6 show examples of floor plans for the first floor of a building. In the examples shown in Figs. 5 and 6, the bearing walls extracted in step S4 are indicated by diagonal lines.

[0052] Next, the control unit 11 divides the plan view of the first floor of the building acquired in step S3 into four parts in the east-west direction and the north-south direction (step S5). Fig. 5 is a plan view of the first floor of a building divided in the north-south direction. In the example shown in Fig. 5, the dividing line in the north-south direction is indicated by a dashed line. 5, in a plan view divided in the north-south direction, the area on the northern end side is designated as area Xa, and the area on the southern end side is designated as area Xb. Fig. 6 is a plan view of the first floor of a building divided in the east-west direction. In the example shown in Fig. 6, the dividing line in the east-west direction is indicated by a dashed line. 6, in a plan view divided in the east-west direction, the area on the west side is designated as area Ya, and the area on the east side is designated as area Yb.

[0053] Next, the control unit 11 calculates the floor area of ​​the entire first floor of the building, the area Xa, the area Xb, the area Ya, and the area Yb (step S6). FIG. 7 shows an example of the floor areas of the entire first floor of the building, area Xa, area Xb, area Ya, and area Yb calculated in step S6. In step S6, the control unit 11 may accept an input operation by the user via the operation unit 15 of the floor areas of the entire first floor of the building, the area Xa, the area Xb, the area Ya, and the area Yb.

[0054] Next, the control unit 11 calculates the wall lengths (wall widths) in the east-west and north-south directions for the entire first floor of the building for the bearing walls extracted in step S4. Furthermore, the control unit 11 calculates the wall lengths in the east-west direction for the bearing walls extracted in step S4 in areas Xa and Xb. Furthermore, the control unit 11 calculates the wall lengths in the north-south direction for the bearing walls extracted in step S4 in areas Ya and Yb (step S7). FIG. 8 shows an example of the lengths of the bearing walls in the entire first floor of the building, the area Xa, the area Xb, the area Ya, and the area Yb calculated in step S7. In step S7, the control unit 11 may accept an input operation by the user via the operation unit 15 of the lengths of the bearing walls in the entire first floor of the building, the areas Xa, Xb, Ya, and Yb.

[0055] Next, the control unit 11 determines the balance of the bearing walls in the building based on the building information acquired in step S1, the building specifications determined in step S2, the floor areas of the entire first floor of the building and the divided areas calculated in step S6, and the lengths of the bearing walls in the entire first floor of the building and the divided areas calculated in step S7 (step S8). The divided areas are area Xa, area Xb, area Ya, and area Yb. That is, the control unit 11 judges the layout balance of the bearing walls in the building based on the building information and the design information. The control unit 11 functions as a second judgment unit.

[0056] In step S8, the control unit 11 calculates the wall volume sufficiency rates of the bearing walls in the east-west direction in each of the areas Xa and Xb. Next, if the wall volume filling rates in both areas Xa and Xb are equal to or greater than 1, the control unit 11 determines that the east-west direction layout balance of the bearing walls is "OK." On the other hand, if at least one of the wall volume filling rates in areas Xa and Xb is less than 1, the control unit 11 calculates the wall volume ratio of the bearing walls in the east-west direction in areas Xa and Xb. Next, if the wall ratio ratio in the east-west direction is 0.5 or more, the control unit 11 judges the layout balance of the bearing walls in the east-west direction to be "OK." On the other hand, if the wall ratio ratio in the east-west direction is less than 0.5, the control unit 11 judges the layout balance of the bearing walls in the east-west direction to be "NG."

[0057] Moreover, the control unit 11 calculates the wall volume sufficiency ratios of the bearing walls in the north-south direction in each of the areas Ya and Yb. Next, when the wall amount filling ratios in both areas Ya and Yb are equal to or greater than 1, the control unit 11 determines that the layout balance of the bearing walls in the north-south direction is "OK." On the other hand, when at least one of the wall amount filling ratios in areas Ya and Yb is less than 1, the control unit 11 calculates the wall ratio ratio of the bearing walls in the north-south direction in areas Ya and Yb. Next, if the wall ratio ratio in the north-south direction is 0.5 or more, the control unit 11 judges the layout balance of the bearing walls in the north-south direction to be "OK." On the other hand, if the wall ratio ratio in the north-south direction is less than 0.5, the control unit 11 judges the layout balance of the bearing walls in the north-south direction to be "NG."

[0058] FIG. 9 shows an example of the wall amount fulfillment rate and the wall rate ratio in the area Xa, the area Xb, the area Ya, and the area Yb, and an example of the layout balance determination. In the example shown in FIG. 9, the wall amount fulfillment rate in area Xb is less than 1, but the wall rate ratio in the east-west direction in areas Xa and Xb is 0.5 or more, so the layout balance in the east-west direction is judged to be "OK." In addition, in the example shown in Figure 9, the wall amount fulfillment rates in both areas Ya and Yb are less than 1, but the wall rate ratio in the north-south direction in areas Ya and Yb is 0.5 or more, so the layout balance in the north-south direction is judged to be ``OK.''

[0059] Next, the control unit 11 judges whether or not the bearing strength of the current bearing walls on the first floor of the building is insufficient (step S9). Specifically, the control unit 11 calculates the necessary strength for the entire first floor of the building based on the building information acquired in step S1 and the floor area of ​​the entire first floor of the building calculated in step S6. Next, the control unit 11 calculates the existing strengths of the first floor of the building in the east-west and north-south directions based on the building information acquired in step S1, the building specifications determined in step S2, and the lengths of the load-bearing walls in the east-west and north-south directions on the entire first floor of the building calculated in step S7. Next, when the existing strength of the first floor in the east-west direction is less than the required strength of the entire first floor of the building, the control unit 11 determines that the current strength of the first floor in the east-west direction is insufficient (NG). Also, when the existing strength of the first floor in the north-south direction is less than the required strength of the entire first floor of the building, the control unit 11 determines that the current strength of the first floor in the north-south direction is insufficient (NG). On the other hand, when the existing strength of the first floor in the east-west direction is equal to or greater than the required strength of the entire first floor of the building, the control unit 11 determines that the current strength of the first floor in the east-west direction is not insufficient (OK). Also, when the existing strength of the first floor in the north-south direction is equal to or greater than the required strength of the entire first floor of the building, the control unit 11 determines that the current strength of the first floor in the north-south direction is not insufficient (OK).

[0060] That is, the control unit 11 judges whether or not the bearing strength of the building is insufficient based on the building information and design information acquired by the acquisition unit 11. The control unit 11 functions as a first judgment unit.

[0061] An example of the strength assessment of the existing bearing walls on the first floor of a building is shown in Fig. 10A. In the example shown in Fig. 10A, the strength of the existing bearing walls in the east-west and north-south directions on the first floor of the building is insufficient (assessed as "NG").

[0062] When the current bearing strength of the bearing walls on the first floor of the building is insufficient (step S9; YES), the control unit 11 calculates the insufficient bearing strength of the bearing walls (step S10). Specifically, the control unit 11 calculates the insufficient strength in the east-west direction by subtracting the existing strength in the east-west direction from the required strength of the entire first floor of the building. Then, the control unit 11 calculates the insufficient strength in the north-south direction by subtracting the existing strength in the north-south direction from the required strength of the entire first floor of the building.

[0063] Next, the control unit 11 accepts an input operation of a reinforcement method for the bearing wall by the user via the operation unit 15. That is, the control unit 11 acquires the reinforcement method (step S11). Specifically, the control unit 11 accepts selection of a reinforcement method for a bearing wall from among options set in advance. The options for the reinforcement method for a bearing wall are, for example, "structural plywood (one-sided)," "single brace," "double brace," etc.

[0064] Next, the control unit 11 calculates the wall lengths that require reinforcement in the east-west direction and the north-south direction (step S12). Specifically, the control unit 11 refers to the reinforcement method table 121 and acquires the wall reference strength of the reinforcement method acquired in step S11. Next, the control unit 11 calculates the wall length that requires reinforcement based on the building information acquired in step S1, the building specifications determined in step S2, the wall volume sufficiency rate calculated in step S8, the insufficient strength calculated in step S10, and the standard strength of the wall.

[0065] In other words, when the control unit 11 determines that the strength of the building is insufficient as the first determination unit, it calculates the length of the bearing wall that needs reinforcement to eliminate the insufficient strength of the building based on the building information and design information. The control unit 11 functions as a wall length calculation unit.

[0066] Figure 10A shows examples of wall lengths requiring reinforcement in the east-west and north-south directions.

[0067] Next, the control unit 11 judges whether or not it is necessary to add a new bearing wall (step S13). Specifically, the control unit 11 judges whether the wall length requiring reinforcement in the east-west direction calculated in step S12 is longer than the wall length in the east-west direction of the entire first floor of the building calculated in step S7. If the wall length requiring reinforcement in the east-west direction is longer than the wall length in the east-west direction of the entire first floor of the building, the control unit 11 judges that it is necessary to add a new load-bearing wall in the east-west direction. Furthermore, the control unit 11 judges whether the wall length requiring reinforcement in the north-south direction calculated in step S12 is longer than the wall length in the north-south direction of the entire first floor of the building calculated in step S7. If the wall length requiring reinforcement in the north-south direction is longer than the wall length in the north-south direction of the entire first floor of the building, the control unit 11 judges that it is necessary to add a new bearing wall in the north-south direction.

[0068] In the example shown in Fig. 10A, the wall length in the east-west direction that needs reinforcement is 8.88 m, and in the example shown in Fig. 8, the wall length in the east-west direction on the entire first floor of the building is 12.00 m. Therefore, the control unit 11 determines that it is not necessary to add a new bearing wall in the east-west direction. In the example shown in Fig. 10A, the wall length in the north-south direction that needs to be reinforced is 10.08 m, and in the example shown in Fig. 8, the wall length in the north-south direction of the entire first floor of the building is 9.10 m. Therefore, the control unit 11 determines that it is necessary to add a new bearing wall in the north-south direction.

[0069] When it is necessary to add a new bearing wall (step S13; YES), the control unit 11 calculates the length of the existing bearing wall to be reinforced and the length of the newly added bearing wall (step S14). Specifically, the control unit 11 sets the wall length of the entire first floor of the building calculated in step S7 as the length of the existing bearing wall to be reinforced. Furthermore, the control unit 11 determines the length of the newly added bearing wall to be the value obtained by subtracting the wall length of the entire first floor of the building calculated in step S7 from the wall length requiring reinforcement calculated in step S12.

[0070] In the example shown in FIG. 10B, the control unit 11 sets the length of the existing bearing wall to be reinforced in the north-south direction to 9.10 m, which is the wall length in the north-south direction of the entire first floor of the building (see FIG. 8). In addition, in the example shown in Figure 10B, the control unit 11 sets the length of the newly added load-bearing wall in the north-south direction to 0.98 m, which is calculated by subtracting 9.10 m, which is the wall length of the entire first floor of the building, from 10.08 m (see Figure 10A), which is the wall length that needs reinforcement.

[0071] On the other hand, if there is no need to add a new bearing wall (step S13; NO), the control unit 11 sets the wall length requiring reinforcement calculated in step S12 as the length of the existing bearing wall to be reinforced (step S15). In the example shown in FIG. 10B, the control unit 11 sets the length of the existing bearing wall to be reinforced in the east-west direction to 8.88 m, which is the wall length that requires reinforcement in the east-west direction (see FIG. 10A).

[0072] Next, the control unit 11 calculates the construction costs for reinforcing the bearing walls in the east-west direction and the north-south direction (step S16). Specifically, the control unit 11 refers to the reinforcement method table 121 and acquires the reinforcement cost per meter of the reinforcement method acquired in step S11. Next, the control unit 11 calculates the construction cost for reinforcing the bearing walls based on the length of the existing bearing walls to be reinforced, the length of the newly added bearing walls, and the reinforcement cost per meter.

[0073] That is, the control unit 11 calculates the reinforcement cost for reinforcing the bearing wall based on the length of the bearing wall that needs reinforcement, which is calculated by the wall length calculation unit. The control unit 11 functions as a cost calculation unit.

[0074] Next, the control unit 11 displays the seismic diagnosis result on the determination screen 142 shown in FIG. 11 on the display unit 14 (step S17), and ends this process. Specifically, the control unit 11 displays on the judgment screen 142 the judgment result of the arrangement balance of the bearing walls in the east-west direction and the north-south direction judged in step S8. That is, the control unit 11, as a second determination unit, displays the result of determining the arrangement balance of the bearing walls on the display unit 14. The control unit 11 functions as a second display control unit.

[0075] Furthermore, the control unit 11 displays, on the judgment screen 142, a proposal for reinforcing the bearing walls based on the judgment result of the layout balance. For example, as shown in FIG. 11, if the layout balance in the east-west and north-south directions is judged to be "OK," the control unit 11 will display a comment, for example, "The balance of the load-bearing walls seems good. We will plan earthquake reinforcement and floor plan while maintaining the balance." In addition, if the layout balance in the east-west direction is judged to be "NG" and the wall volume sufficiency rate of area Yb (the area on the eastern end) is less than 1, the control unit 11 will display a comment, for example, "The balance of the load-bearing walls appears to be poor. The plan is to focus earthquake reinforcement on the east side." In addition, if the layout balance in the east-west direction is judged to be "NG" and the wall volume sufficiency rate of area Ya (the area on the western end) is less than 1, the control unit 11 will display a comment, for example, "The balance of the load-bearing walls appears to be poor. The plan is to focus earthquake reinforcement on the west side." In addition, if the layout balance in the north-south direction is judged to be "NG" and the wall volume sufficiency rate of area Xb (the area on the southern end) is less than 1, the control unit 11 will display a comment, for example, saying, "The balance of the load-bearing walls appears to be poor. We plan to focus earthquake reinforcement on the south side." In addition, if the layout balance in the north-south direction is judged to be "NG" and the wall volume sufficiency rate of area Xa (the area on the northern end) is less than 1, the control unit 11 will display a comment, for example, "The balance of the load-bearing walls appears to be poor. The plan is to focus earthquake reinforcement on the north side."

[0076] Furthermore, the control unit 11 displays on the judgment screen 142 the strength judgment results of the current bearing walls in the east-west direction and the north-south direction judged in step S9. That is, the control unit 11, as a first determination unit, displays the result of determining whether or not the bearing strength of the building is insufficient on the display unit 14. The control unit 11 functions as a first display control unit.

[0077] If the strength judgment result of the existing bearing walls in the east-west or north-south direction is judged as "NG," the control unit 11 displays, on the judgment screen 142, the lengths of the existing bearing walls to be reinforced and the lengths of the newly added bearing walls set in steps S14 and S15. Furthermore, the control unit 11 displays, on the judgment screen 142, the construction costs for reinforcing the bearing walls calculated in step S16.

[0078] Moreover, when the bearing strength of the current bearing walls on the first floor of the building is not insufficient (step S9; NO), the control unit 11 shifts the process to step S17. In this case, in step S17, the control unit 11 displays an "OK" judgment for the strength judgment result of the current bearing walls in the east-west direction and the north-south direction.

[0079] Here, a case where a floor plan of the first floor of a building designed using the reference dimension (module) is obtained in the above step S3 will be described. The reference dimension is set to, for example, 910 mm, but is not limited to this, and may be, for example, 1000 mm or other dimensions. In this case, since the load-bearing walls and floor area of ​​the first floor of the building are set based on the standard dimensions, the control unit 11 can easily calculate the floor area of ​​the entire first floor of the building and the divided area in step S6, and can easily calculate the length of the load-bearing walls of the entire first floor of the building and in the divided area in step S7.

[0080] 3. Effects As described above, the seismic diagnosis device 1 of this embodiment includes an acquisition unit (control unit 11) that acquires building information related to a building and design information of the building, a first judgment unit (control unit 11) that judges whether or not the building has insufficient strength based on the building information and the design information acquired by the acquisition unit, and a wall length calculation unit (control unit 11) that, when it is judged by the first judgment unit that the building has insufficient strength, calculates the length of a bearing wall that needs to be reinforced to eliminate the insufficient strength of the building based on the building information and the design information. According to this, the user can easily understand the result of the assessment of the earthquake resistance of the building by inputting the building information and the design information. Also, if the building is judged to have insufficient strength, the user can easily understand the length of the bearing wall that needs reinforcement. Therefore, it is possible to easily judge the earthquake resistance of a building and propose reinforcement work.

[0081] In the earthquake resistance diagnosis device 1 of this embodiment, the building information includes the new construction date of the building, and the first judgment unit (control unit 11) judges the specifications of the building based on the new construction date, and judges whether the building has insufficient strength based on the judgment result of the building specifications. This makes it possible to identify the specifications of a building based on when the building was constructed, thereby eliminating the need to spend time identifying the specifications of existing buildings. Therefore, the earthquake resistance of a building can be determined in a simple manner.

[0082] In the seismic diagnosis device 1 of this embodiment, the first judgment unit (control unit 11) extracts walls in the design information that do not have openings as load-bearing walls, and judges whether the building has insufficient load-bearing strength based on the length of the load-bearing walls. This allows the user to save the trouble of inputting the positions, lengths (widths), etc. of the load-bearing walls of a building during earthquake resistance diagnosis of the building. Therefore, the earthquake resistance of a building can be determined in a simple manner.

[0083] In the seismic resistance diagnosis device 1 of this embodiment, the wall length calculation unit (control unit 11) calculates the length of a new load-bearing wall to be installed in the building when the length of the load-bearing wall that needs reinforcement is longer than the length of the load-bearing wall installed in the building. According to this, when it is determined that a building has insufficient strength and the length of a load-bearing wall that needs reinforcement is longer than the length of a load-bearing wall installed in the building, the user can easily determine the length of a new load-bearing wall to be installed in the building. Therefore, proposals for reinforcement work can be made easily.

[0084] The seismic diagnosis device 1 of this embodiment is equipped with a cost calculation unit (control unit 11) that calculates the reinforcement cost of reinforcing the load-bearing wall based on the length of the load-bearing wall that requires reinforcement calculated by the wall length calculation unit (control unit 11). With this, if it is determined that a building's strength is insufficient, the user can easily grasp the length of the bearing walls that need reinforcement and the reinforcement costs. Therefore, proposals for reinforcement work can be made easily.

[0085] The earthquake resistance diagnosis device 1 of this embodiment is equipped with a first display control unit (control unit 11) that displays the judgment result made by the first judgment unit (control unit 11) as to whether or not the building has insufficient strength on a display unit 14, and when the first judgment unit judges that the building has insufficient strength, the first display control unit displays on the display unit 14 the length of the bearing wall that needs reinforcement calculated by the wall length calculation unit (control unit 11) and the reinforcement cost calculated by the cost calculation unit (control unit 11). With this, if it is determined that a building's strength is insufficient, the user can easily grasp the length of the bearing walls that need reinforcement and the reinforcement costs. Therefore, proposals for reinforcement work can be made easily.

[0086] The earthquake resistance diagnosis device 1 of this embodiment includes a second determination unit (control unit 11) that determines the layout balance of the bearing walls in the building based on the building information and the design information. This allows the user to easily grasp the balance of the placement of load-bearing walls in a building by inputting building information and design information. Therefore, it is possible to easily judge the earthquake resistance of a building and propose reinforcement work.

[0087] In the seismic resistance diagnosis device 1 of this embodiment, the second judgment unit (control unit 11) judges the north-south placement balance of the building's load-bearing walls based on the floor area and the lengths of the load-bearing walls in the northern and southern end areas obtained by dividing the building's floor plan into four parts in the north-south direction, and judges the east-west placement balance of the building's load-bearing walls based on the floor area and the lengths of the load-bearing walls in the eastern and western end areas obtained by dividing the building's floor plan into four parts in the east-west direction. This allows the user to easily grasp the balance of the placement of load-bearing walls in the north-south and east-west directions of the building by inputting building information and design information. Therefore, it is possible to easily judge the earthquake resistance of a building and propose reinforcement work.

[0088] The seismic diagnosis device 1 of this embodiment is equipped with a second display control unit (control unit 11) that displays the judgment result of the placement balance of the load-bearing walls by the second judgment unit (control unit 11) on the display unit 14, and the second display control unit displays suggestions for reinforcing the load-bearing walls on the display unit 14 based on the judgment result of the placement balance of the load-bearing walls by the second judgment unit. This allows a user to easily grasp the balance of the placement of load-bearing walls in a building and proposals for reinforcing the load-bearing walls by inputting building information and design information. Therefore, it is possible to easily judge the earthquake resistance of a building and propose reinforcement work.

[0089] The program of this embodiment causes the computer (control unit 11) of the seismic diagnosis device 1 to function as an acquisition unit that acquires building information related to a building and design information of the building, a first judgment unit that judges whether the building has insufficient strength based on the building information and the design information acquired by the acquisition unit, and a wall length calculation unit that, when it is judged by the first judgment unit that the building has insufficient strength, calculates the length of a bearing wall that needs to be reinforced to eliminate the insufficient strength of the building based on the building information and the design information. According to this, the user can easily understand the result of the assessment of the earthquake resistance of the building by inputting the building information and the design information. Also, if the building is judged to have insufficient strength, the user can easily understand the length of the bearing wall that needs reinforcement. Therefore, it is possible to easily judge the earthquake resistance of a building and propose reinforcement work.

[0090] Although the present invention has been specifically described based on the embodiment, the present invention is not limited to the above embodiment and can be modified without departing from the gist of the present invention. For example, in the above embodiment, the earthquake resistance diagnosis process diagnoses the earthquake resistance of the first floor of a multi-story building or a single-story building, but the present invention is not limited to this. The earthquake resistance diagnosis process may be performed on the second or higher floors of a multi-story building.

[0091] Furthermore, the building of this embodiment is constructed by a general framework construction method, but is not limited to this, and may be constructed by a panel construction method, a wall construction method, a two-by-four construction method, etc. In the panel construction method, building components such as walls, floors, and roofs are made into panels in advance at a factory, and these panels (construction wood panels) are assembled at the construction site to construct the building.

[0092] This panel is a structure in which vertical and horizontal frame members are assembled into a rectangular shape, auxiliary rail members are assembled vertically and horizontally inside the rectangular frame to form a frame body, and a facing material (e.g., plywood) is attached to both sides or one side of this frame body, resulting in a hollow structure. Furthermore, the hollow part is usually filled with a heat insulating material such as glass wool or rock wool.

[0093] In recent years, there has been a demand for the realization of a decarbonized society through the promotion of carbon neutrality, which reduces carbon dioxide emissions to virtually zero, and for the achievement of the SDGs (Sustainable Development Goals). In the construction industry, too, efforts are being made to build buildings using wood, which has low carbon dioxide emissions. The building of this embodiment is partially constructed using wood. Therefore, it can contribute to the realization of a decarbonized society through the promotion of carbon neutrality and the achievement of the SDGs. [Explanation of symbols]
