Description

[Technical Field]

[0001] The present invention relates to a design support device and a design support method, and more particularly to a technology that enables environmental vibration risk to be examined economically and efficiently. [Background technology]

[0002] Although environmental vibrations such as traffic vibrations and factory vibrations are smaller in intensity than vibrations caused by earthquakes and other factors, they occur very frequently. As a result, it is not uncommon for residents of buildings affected by such vibrations to feel discomfort and anxiety due to the vibrations. Therefore, it is important to thoroughly consider the presence or absence of the above environmental vibrations before the building is constructed (at the design stage). In practice, such considerations involve "checking vibration sources at the construction site," "on-site vibration surveys before construction," and "predicting vibrations within the building based on the vibration survey results."

[0003] As a conventional technique related to the above-mentioned study of environmental vibrations, for example, a technique has been proposed in which vibration level predictions are made taking into account the resonance between a building and external vibrations, and traffic vibration occurrences are predicted based on said predictions, and active vibration suppression measures are provided for traffic vibrations, thereby realizing the location of houses near traffic vibration sources and the comfortable living environment of said houses (see Patent Document 1).

[0004] Specifically, this technology relates to a method for predicting vibration levels within a building, characterized by adding one of two levels of average vibration level amplification, classified according to the presence or absence of resonance between the ground vibration and the building, for buildings with the same structural system as the building in question, to the ground vibration level measured by vibration measurement.

[0005] Additionally, a technology has been proposed (see Patent Document 2) that provides a building design method that can ensure economical and comfortable living without over-designing even in frequency bands where the natural frequency of the building and the main frequency of ground vibration are far apart and no resonant vibration occurs.

[0006] This technology relates to a method for predicting vibration levels of buildings, which is characterized by measuring the vibration level of the ground on which a building is to be constructed and analyzing the vibration level for each frequency, calculating the natural frequency of the building, calculating the amplification amount of the input vibration level of the building from a relationship of the amplification amount of the input vibration level to the natural frequency created in advance based on the calculated value, and predicting the vibration level of the building for each frequency by adding the measured vibration level of the ground on which the building is to be constructed to the calculated value.

[0008] However, the methods shown in conventional technology involve surveys and examinations for each individual building, and are not applicable to a wide range of buildings before (or without) conducting on-site vibration surveys. Meanwhile, with the recent trend toward teleworking, the proportion of people working from home is increasing, and sensitivity to the above-mentioned environmental vibrations is also on the rise. Therefore, while there is a need to examine the above-mentioned environmental vibrations for many buildings, it is difficult to secure the human and financial resources to respond to each individual case.

[0009] Therefore, the present invention has been made in consideration of the above-mentioned problems, and its purpose is to provide a technology that enables environmental vibration risk to be examined economically and efficiently. [Means for solving the problem]

[0010] The above problem is solved by a design support device that supports the design of buildings to be constructed at designated points within a target area, the design support device having: a storage unit that stores, for each of two or more survey points set in the target area, survey results regarding the magnitude of ground vibrations that will occur at the survey point and prediction results regarding the magnitude of shaking caused by the ground vibrations that will be felt in buildings at the survey point in a database, in association with location information of the survey point and the micro-topography category to which the survey point belongs; an acquisition unit that acquires input information for the designated points, including the location information of the designated point and the micro-topography category to which the designated point belongs; an extraction unit that extracts the survey results and prediction results from the database for specific survey points among the two or more survey points that belong to the same micro-topography category as the designated point; and a display unit that displays the survey results and prediction results extracted for the specific survey points.

[0011] The design support device of the present invention configured as described above makes it possible to economically and efficiently carry out an examination of environmental vibration risks. More specifically, the device can support the design of a building at a specified location by using information (e.g., predicted shaking according to the number of floors) on a survey location that is expected to exhibit vibration behavior similar to that of a specified location among multiple survey locations.

[0012] In addition, in the above design support device, Preferably, when there are multiple specific survey points, the extraction unit extracts the survey results and prediction results for each of the multiple specific survey points from the database, and the display unit displays the survey results and prediction results extracted for each of the multiple specific survey points in an order according to the distance between the specific survey point and the designated point.

[0013] The above configuration makes it possible to display multiple existing data sets with the same location and micro-topography classification in order of proximity to a specified point, thereby enabling more economical and efficient analysis of environmental vibration risks.

[0014] Furthermore, in the above-mentioned design support device, it is preferable that the accumulation unit further holds a terrain classification number that groups together points that have a common micro-topography classification and are adjacent to each other for each point in the target area, and the extraction unit extracts from the database of the survey results and the prediction results the specific survey points among the two or more survey points that belong to the same micro-topography classification as the designated point and have the same terrain classification number as the designated point.

[0015] The above configuration makes it possible to separate areas even if the micro-topography is the same, and to avoid treating locations with potentially different geology as the same and using survey and prediction results. This ultimately makes it possible to carry out environmental vibration risk studies more economically and efficiently.

[0016] Furthermore, in the above-mentioned design support device, it is preferable that the accumulation unit accumulates the survey results and the prediction results for each of the two or more survey points in the database in association with the location information of the survey point, the micro-topography classification, and the source of ground vibration at the survey point, and that the extraction unit extracts the survey results and the prediction results from the database for the specific survey points among the two or more survey points that belong to the same micro-topography classification as the designated point and have a common vibration source with the designated point.

[0017] According to the above configuration, it is possible to extract existing data taking into account commonality of vibration sources, which in turn makes it possible to more economically and efficiently study environmental vibration risks.

[0018] Furthermore, in the above-mentioned design support device, it is preferable that the accumulation unit accumulates in the database, as the prediction results, prediction results obtained for each of the two or more survey locations by changing the specifications of the building at the survey location, and that the display unit, when displaying the prediction results for the specific survey location, displays the prediction results for each of the specifications.

[0019] According to the above configuration, it is possible to display predicted results of shaking that may differ depending on the specifications of the building (number of floors, etc.), which in turn makes it possible to more economically and efficiently study environmental vibration risks.

[0020] In addition, according to the design support method of the present invention, the above-mentioned problem is solved by executing the following steps in a design support device that supports the design of a building to be constructed at a designated point within a target area: a process of storing in a database, for each of two or more survey points set in the target area, survey results regarding the magnitude of ground vibrations that will occur at the survey point and predicted results regarding the magnitude of shaking caused by the ground vibrations that will be felt in buildings at the survey point, in association with the location information of the survey point and the micro-topography category to which the survey point belongs; a process of acquiring input information for the designated points, including the location information of the designated point and the micro-topography category to which the designated point belongs; an extraction unit that extracts the survey results and predicted results from the database for specific survey points among the two or more survey points that belong to the same micro-topography category as the designated point; and a process of displaying the survey results and predicted results extracted for the specific survey points.

[0021] According to the above design support device, it is possible to economically and efficiently carry out a study of environmental vibration risks. [Effects of the Invention]

[0024] <<System Configuration Including the Design Support Device of This Embodiment>> The configuration of a design support system 100 according to the present invention, a method executed by the design support system 100, and a program therefor will be described below with reference to the accompanying drawings, taking one embodiment of the present invention (hereinafter referred to as the present embodiment) as an example. However, the embodiment described below is merely an example given to facilitate understanding of the present invention and does not limit the present invention. In other words, the present invention may be modified or improved from the embodiment described below without departing from the spirit of the present invention. Naturally, the present invention also includes equivalents thereof.

[0025] Furthermore, the screen examples shown in the drawings referenced in the following description are merely examples, and the screen configuration examples, the content of the information displayed, and the GUI (Graphical User Interface), etc., can be freely designed according to the system design specifications and user preferences, and can be changed as appropriate.

[0026] In addition, in this specification, the term "device" includes not only one device that performs a predetermined function on its own, but also multiple devices that are separate from each other but work together to perform a predetermined function.

[0027] First, an example of a design support system 1 including a design support device 100 according to this embodiment will be described. FIG. 1 is a diagram showing an example of a network configuration including the design support device 100 according to this embodiment. The design support device 100 is configured to be communicably connected to an information disclosure server 20 and a user terminal 30 via a network N. The design support device 100 is an information processing device that executes each process corresponding to the design support method of the present invention. The information disclosure server 20 is a server device that publishes, on the network N, some or all of information that can be used to execute the design support method of the present invention, such as microtopography classifications and ground characteristics of various locations. Such information disclosure server 20 is a server of various government agencies, local governments, designated businesses, etc. Furthermore, the user terminal 30 is a terminal used by personnel of construction companies, local governments, etc. who wish to use the design support functions of the design support device 100.

[0028] It should be noted that this network configuration is merely one example, and various configurations can be adopted, including a configuration in which the design support device 10 is configured as an integrated device with the information disclosure server 20 and the user terminal 30, or a configuration in which all or part of the configuration and functions of the design support device 10 are provided in at least one of the information disclosure server 20 and the user terminal 30 and the design support method of the present invention is executed, and is not limited to this.

[0029] <Hardware configuration of the design support system> The design support device 100 of this embodiment is a computer device that executes the processing of each step in the design support method of the present invention. Therefore, in addition to the hardware configuration shown in FIG. 2, it has functional units (storage unit 11, acquisition unit 12, extraction unit 13, and display unit 14) as shown in FIG. 3. The design support device 10 has a configuration as a general information processing device, including an auxiliary storage device 101, a main storage device 103, a processor 104, an input device 105, an output device 106, and a communication device 107. The design support device 10 of this embodiment may be configured as a single information processing device as shown in the figure, or may be configured as a plurality of information processing devices distributed in parallel. Alternatively, the design support device 10 may be configured as an information processing device for an ASP (Application Service Provider), SaaS (Software as a Service), PaaS (Platform as a Service), or IaaS (Infrastructure as a Service).

[0030] Here, on the assumption that the design support device 10 in this embodiment is composed of a single information processing device, the configuration of the design support device 10 is illustrated in which an auxiliary memory device 101, a main memory device 103, a processor 104, an input device 105, an output device 106, and a communication device 107 are connected by a bus.

[0031] In the above configuration, the auxiliary storage device 101 is implemented by a non-volatile storage device or storage medium, such as an HDD (Hard Disk Drive), SSD (Solid State Drive), flash memory, FD (Flexible Disc), MO disk (Magneto-Optical disc), CD (Compact Disc), DVD (Digital Versatile Disc), SD card (Secure Digital card), or USB memory (Universal Serial Bus memory).

[0032] The auxiliary storage device 101 may be built into the housing of the design support device 10, or may be externally connected to the design support device 10. The auxiliary storage device 101 may be formed by another computer or the like communicably connected to the design support device 10. A distributed ledger technology such as a blockchain may be used as a technology for recording various data in order to prevent unauthorized data tampering. The auxiliary storage device 101 in this embodiment stores a survey result DB 111, a prediction result DB 112, microtopography classification information 113, and map data 114. The map data 114 and the like used by the display unit 14 are also held in the auxiliary storage device 101 and are read and used by the display unit 14 as needed.

[0033] The main storage device 103 may be configured with volatile semiconductor memory such as a read-only memory (ROM) and a random access memory (RAM). The main storage device 103 in this embodiment stores a program 102 including an operating system (OS) read from the auxiliary storage device 101, and a map generation engine (not shown) that is implemented as needed.

[0034] Of these, the OS controls the design support device 10 itself and implements basic functions, and under its control, the processor 104 calls and executes each unit of the program 102, thereby implementing each function corresponding to the design support method, namely, the storage unit 11, the acquisition unit 12, the extraction unit 13, and the display unit 14. The processor 104 may be configured by a CPU (Central Processing Unit), an MPU (Micro-Processing Unit), an MCU (Micro Controller Unit), a GPU (Graphics Processing Unit), a DSP (Digital Signal Processor), a TPU (Tensor Processing Unit), an ASIC (Application Specific Integrated Circuit), or the like.

[0035] The input device 105 mainly corresponds to a keyboard and a mouse, but may also include other appropriate input devices such as a touch panel, a microphone, etc. On the other hand, the output device 106 corresponds to a display and a speaker, but may also include other output devices.

[0036] The communication device 107 is implemented as a communication chipset compatible with, for example, 3G to 5G or later generation mobile communication protocols, or the LTE (Long Term Evolution) protocol. However, the communication device 107 may be implemented as other devices depending on the type of network N. For example, if the network N is configured as a wireless LAN, the communication device 107 will be implemented as a network interface card compatible with the wireless LAN protocol based on Wi-fi (registered trademark).

[0037] <Functional configuration of the design support system> Among the functional units included in the design support device 10, the accumulation unit 11 holds, in the auxiliary storage device 101, a survey result DB 111, a prediction result DB 112, micro-topography classification information 113, and map data 114. Of these, at least the micro-topography classification information 113 and the map data 114 are acquired from the information disclosure server 20 or the user terminal 30 via the communication device 107.

[0038] The acquisition unit 12 is also a functional unit that acquires input information, including location information of a designated location (a planned construction site) from which information on the magnitude of shaking caused by ground vibration is to be acquired, and the micro-topography category to which the designated location belongs. In this case, the location information among the input information may be the address or latitude / longitude coordinate values ​​of the designated location, and may correspond to values ​​acquired by the acquisition unit 12 in response to a user's selection on a map displayed on the display unit 14 or the user terminal 30 (obviously, there are no limitations on the acquisition format or route of such location information; the same applies below). The micro-topography category may correspond to a value selected by the user in a selection interface (e.g., a pull-down menu) displayed on the display unit 14 or the user terminal 30 by the acquisition unit 12. In other words, the acquisition unit 12 receives or directly accepts the input information when the user operates the user terminal 30 or the input device 105 to input the input information.

[0039] Furthermore, the extraction unit 13 identifies specific survey points that belong to the same micro-landform division as the above-mentioned designated point (designated by the user) from among the survey points held in the survey result DB 111 and the prediction result DB 112. At this time, the acquisition unit 12 compares the user-designated micro-landform division acquired by the acquisition unit 12 with the micro-landform division information 113, and identifies the point that falls under the micro-landform division, i.e., the specific survey point, and its location information. Furthermore, the extraction unit 13 uses the location information of the above-mentioned specific survey point as a key to extract survey results for the specific survey point from the survey result DB 111 and similarly extract prediction results from the prediction result DB 112.

[0040] The display unit 14 is also a functional unit that displays the survey results and prediction results extracted for the specific survey points by the extraction unit 13 on the user terminal 30 or the output device 106. In this case, the display unit 14 extracts map data for a certain area including the specific survey points from the map data 114, and generates screen data on this map data in which objects such as predetermined icons and text are placed at positions corresponding to each of the specific survey points.

[0041] In generating the screen data, the display unit 14 preferably applies coloring or text to each target area (rectangular area defined as a micro-topography area) according to the micro-topography area of ​​each point corresponding to the area for which map data is generated, thereby clearly visualizing the distribution of the micro-topography areas of the specified point and the area surrounding it. This can also be preferably achieved by controlling the type and color of the dot or icon indicating the survey point according to the type of vibration source (e.g., railway, general road, etc.) indicated by the survey results or prediction results.

[0042] The display unit 14 outputs the above screen data to the user terminal 30 or the output device 106 and displays it on the screen. The display unit 14 displays some or all of the survey results and prediction results on this screen, or places links for displaying that information (for example, links that launch a pop-up screen or the like that displays the target information in response to a click) for the user to view.

[0043] In addition, if there are multiple specific survey points, the display unit 14 lists the survey results and prediction results extracted for each of the specific survey points in an order according to the distance between the specific survey point and the designated point, i.e., in order of proximity to the designated point, or assigns numbers (for example, "rank 1" to the closest one) or specific icons to the survey results and prediction results in order of proximity and displays them.

[0044] Furthermore, in this embodiment, the micro-terrain division information 113 held by the accumulation unit 11 includes a micro-terrain division and a terrain division number (described in detail later in FIG. 7) assigned to each point in the target area. The terrain division number is a value assigned to each group of points that share a common micro-terrain division and are adjacent to each other. In this case, the extraction unit 13 identifies specific survey points among the survey points that belong to the same micro-terrain division as the designated point and have the same terrain division number as the designated point, and extracts survey results and prediction results for those specific survey points.

[0045] In this embodiment, the survey result DB 111 and the prediction result DB 112 stored in the accumulation unit 11 also store information on the source of ground vibration at each survey point. In this case, the extraction unit 13 identifies specific survey points among the survey points that belong to the same microtopography as the designated point and have the same vibration source as the designated point, and extracts the survey results and prediction results for the specific survey points.

[0046] Furthermore, in this embodiment, the accumulation unit 11 stores, for each survey point, prediction results acquired for each of the specifications (e.g., number of floors and type of structure) of a building that can be expected to be constructed at the survey point, with multiple patterns, in the prediction result DB 112. In this case, when displaying the prediction results for a specific survey point, the display unit 14 displays the prediction results for each of the specifications.

[0047] (Regarding databases, etc.) Next, the types of data used by the design support device 10 of this embodiment will be described with reference to Figs. 4 to 8. Fig. 4 is a diagram showing an example of the configuration of the survey result DB 111 in this embodiment. The survey result DB 111 is a database that stores, for example, the results of environmental vibration surveys that have been conducted in the past by the operator of the design support device 10. The survey result DB 111 is made up of records that link values ​​such as the survey target area, point, location information of the point, survey time, estimated vibration source, and ground surface vibration acceleration level using a number that uniquely identifies the record as a key.

[0048] Furthermore, the prediction result DB112 in this embodiment is a database that stores, for example, prediction results of vibrations in a building at a survey point, which are predicted based on the results of an environmental vibration survey previously conducted by the operator of the design support device 10. The prediction result DB112 is composed of records that use a number that uniquely identifies the record as a key to link values ​​such as the target area of ​​the prediction, the point, location information of the point, estimated vibration source, building specifications, and building vibration acceleration level. Of these, the building specifications specify the number of floors of the building (2-story, 3-story, ...) and structure type (wooden, light-gauge steel frame, heavy-gauge steel frame, ...).

[0049] The information on "building vibration acceleration level" in the prediction result DB 112 includes values ​​calculated by a known method using the data on "ground vibration acceleration level" in the records of the target location among the records in the survey result DB 111. This known method is, for example, the so-called "1 / 3 octave band analysis." By performing this analysis, the graph shown in Figure 6 (horizontal axis: 1 / 3 octave band center frequency, vertical axis: vibration acceleration level) is obtained, plotting the predicted values ​​of ground vibration and vibration on the top floor of the building.

[0050] Furthermore, for example, in the case of a certain specification A (e.g., a three-story wooden building), the vibration acceleration level for each frequency shown in this graph is amplified by a predetermined percentage in a certain frequency range of f1 [Hz] to f2 [Hz] (the gray range in Figure 6), and then the parts that fall on a predetermined evaluation curve (Architectural Institute of Japan, "Guidelines and Commentary on Habitability Performance Evaluation Regarding Vibration of Buildings") are identified. In the example shown in Figure 6, the plot in that frequency range falls on "H-50," so the "Habitability Performance Evaluation Index: H-50" is determined for this specification A. Of course, the above method is merely an example, and other methods may be adopted as appropriate.

[0051] Furthermore, the micro-topography classification information 113 of this embodiment is information that defines the micro-topography classification information for each point in the target area. A micro-topography classification is a unit that groups together ground that is homogeneous in terms of origin, form, constituent materials, and formation period within each standard. Specifically, values ​​that correspond to this include mountainous areas, foothills, loamy plateaus, hills, valley bottom lowlands, alluvial fans, sand dunes, reclaimed land, reclaimed land, and river channels. These micro-topography classifications are set nationwide in rectangular areas of 250m square.

[0052] As shown in Fig. 7, the micro-terrain division information 113 of this embodiment is composed of records linking values ​​for the target area, point, position information of the point, micro-terrain division, and terrain division number. Of these, the terrain division number is a serial number assigned to each point in the group when points in the target area that share a common micro-terrain division and are adjacent to each other are grouped. In other words, it is a number assigned to each closed group of points with the same micro-terrain division, and if the same micro-terrain division is separated by an area with a different micro-terrain division, a different terrain division number is assigned.

[0053] Furthermore, the map data 114 of this embodiment stores position information of each point in the target area, as exemplified in Fig. 8. Such map data 114 includes, as data for each point, information such as the location, layout, area, extension direction, and length of buildings, various facilities, railways, roads, etc. that exist at that point. As already mentioned, the map data 114 is acquired from a server (information disclosure server 20) of a map data providing service that manages and distributes map data for each area, and is stored in the auxiliary storage device 101.

[0054] <Flow of design support method> Next, an example of a flow of the design support method according to this embodiment will be described. FIG. 9 shows an example of a flow of the design support method according to this embodiment. In this case, the acquisition unit 12 of the design support device 10 communicates with the user terminal 30 via the network N and acquires, for example, survey results and prediction results for a target area desired by the user or predetermined by the user (S1). Note that the target area is an area designated by the user terminal 30, and corresponds to a location related to a point where an actual survey on environmental vibration (ground vibration) and a prediction of shaking in a building based on the results of the survey were conducted. Furthermore, as an example of the designated value of the target area, a mesh code associated with a mesh in the target area (e.g., administrative divisions such as prefectures, cities, towns, and villages) among the meshes obtained by dividing Japan into squares of 250 m each may be used.

[0055] The accumulation unit 11 of the design support device 10 stores the survey results and prediction results acquired by the acquisition unit 12 as described above in the survey result DB 111 and prediction result DB 112 of the auxiliary storage device 101 (S2). The acquisition unit 12 of the design support device 10 also accepts input of location information and micro-topography classification of a specified point from which information on predicted shaking of a building due to ground vibration is desired to be obtained from the user terminal 30 (S3), and temporarily stores these values ​​in the main storage device 103. At this time, the acquisition unit 12 distributes an input screen for the location information and micro-topography classification to the user terminal 30, and acquires the values ​​through the input screen.

[0056] Next, the extraction unit 13 of the design support device 10 performs a search in the survey result DB 111 and the prediction result DB 112 using the location information of the designated point and the information on the micro-topography category (for example, "reclaimed land") obtained in S3 above as keys, and identifies, from among the multiple survey points existing in the target area, specific survey points that belong to the same micro-topography category and topography category number as the designated point (S4). If there are multiple survey points in the target area that are in the same micro-topography category as the designated micro-topography category and have the same topography category number, then multiple specific survey points will be identified here.

[0057] Furthermore, the extraction unit 13 of the design support device 10 extracts the investigation results and prediction results for the specific investigation points identified in S4 from the investigation result DB 111 and the prediction result DB 112 (S5). Furthermore, the extraction unit 13 of the design support device 10 narrows down the investigation results and prediction results extracted in S5 to those related to a predetermined number (e.g., five) of specific investigation points that share the same type of vibration source (e.g., railway) as the specified point and that are arranged in descending order of distance from the specified point (S6).

[0058] Next, the display unit 14 of the design support device 10 generates a screen G1 that displays the survey results and prediction results for the specific survey points narrowed down in S6 above in a format according to the proximity of the distance from the specified point, and delivers this to the user terminal 30 (or the output device 106) for display (S7). In this case, the display unit 14 generates a map by arranging the map data 114 of the target area on a screen template previously stored in the auxiliary storage device 101, and arranges on this map an object G10 indicating the specified point, an object G11 indicating the specific survey point, and an object G12 indicating the ranking according to the distance from the specified point, thereby generating the screen G1 (see FIG. 10).

[0059] Furthermore, the display unit 14 displays, for example, text information for an object G10 at a specified point on the screen G1, indicating the type of vibration source estimated there. Furthermore, for each survey point (including specific survey points), the display unit 14 displays the object in a different manner depending on the type of vibration source. In the example of FIG. 10, if the type of vibration source is "railway," the object at that survey point is displayed as a black circle, and if the type of vibration source is "general road," the object at that survey point is displayed as a white circle. Furthermore, the display unit 14 performs display control to color-code the type of micro-topography for each mesh of the micro-topography on the map of the screen G1. In the example of FIG. 10, the meshes of each micro-topography, "reclaimed land," "hills," and "alluvial fan," are displayed in different colors.

[0060] Furthermore, it is preferable that the display unit 14 displays, for example, on the screen G1, the magnitude of shaking that is expected when buildings of various specifications are constructed at the specific survey point, based on the prediction results obtained for the specific survey point, i.e., the information on the predicted habitability evaluation explained in Fig. 6. When performing such a display, the display unit 14 performs display control such as popping up screen G2 (see Fig. 11) in response to a click or the like on object G11 of the specific survey point on screen G1.

[0061] As shown in FIG. 11 , the livability evaluation prediction information includes information such as the ranking and distance of the specific survey locations (ranking and distance according to proximity to the designated location), address, ground vibration measurement date and time, ground vibration acceleration level, and building vibration acceleration level prediction results (for each specification). That is, the display unit 14 displays and presents to the user, for each specific survey location, prediction information for at least one of the building vibration acceleration level and the livability evaluation prediction, by building specification. From the user's perspective, when constructing a building at a designated location, the user can visually understand the type of shaking predicted and its significance in terms of livability evaluation, along with information on the type of vibration source and microtopography. This can ultimately be used not only when designing the specifications of a building to be constructed at the specific survey location, but also when proposing a building to a customer, providing sales support information.

[0062] While one embodiment of the design support system and design support method of the present invention has been described above, the above embodiment is merely an example for facilitating understanding of the present invention and does not limit the present invention. In other words, the present invention can be modified and improved without departing from the spirit and scope of the present invention. Furthermore, it goes without saying that the present invention includes equivalents thereof. [Explanation of symbols]
