Description

Technical Field

[0001] The invention belongs to the technical field of building test, and in particular relates to a simulated building wind resistance test device and a test method. Background Art

[0002] A typhoon is a strong tropical cyclone that forms on tropical or subtropical oceans. It generally moves northward to the mainland and then disappears. This process is also called landing. Typhoons pose many hazards to buildings. The first is the direct impact of strong winds. Due to the strong winds of typhoons, huge pressure will be exerted on the structure of the building, especially some old or defective buildings, which may cause wall cracks, collapses, and roof overturns. Secondly, typhoons are often accompanied by heavy rains. The long-term scouring and penetration of rainwater may damage the waterproof layer of the building and cause leakage. If rainwater pours into the wall, it will also affect the stability of the wall structure and pose a serious threat to the structural safety of the building. Therefore, it is necessary to conduct pit wind tests on newly designed buildings before construction. In the prior art, wind tunnels are used to conduct wind resistance tests on buildings that are built in equal proportions. However, during the test, the wind direction and wind speed are often fixed, and the rainfall during the typhoon cannot be simulated, which makes the test conditions very different from the actual typhoon conditions, resulting in low validity of the test results. Summary of the invention

[0003] The present invention provides a simulated building wind resistance test device and test method, which can more realistically simulate typhoons of different grades to test the building, which is beneficial to improving the validity of the test results, and can also generate and display a three-dimensional stereogram, which is helpful to intuitively experience and analyze the force, deformation, inclination and displacement of the building during the test.

[0004] The technical solution adopted by the present invention is:

[0005] A simulated building wind resistance test device and test method, comprising the following steps:

[0006] S1. Obtain soil hardness and soil at the geographical location of the pre-constructed building, and construct a typhoon model, wherein the typhoon model includes multiple groups of typhoon hazard parameters, each group of typhoon hazard parameters corresponds to a single simulated typhoon, and each group of typhoon hazard parameters includes wind speed, wind direction and rainfall loaded in time sequence;

[0007] S2. Compact the collected soil according to the soil hardness to form base soil, build a base on the base soil, and build a building on the base. The base and the building are scaled down in equal proportions, and the materials of the building and the base are the same as the pre-built building construction materials;

The flood parameters include rainfall, flood depth, water flow direction and water flow speed. The rainfall, flood depth, water flow direction and water flow speed in the same group correspond to a single historical flood that has occurred. The corresponding historical flood parameters are screened out according to the maximum flood depth. According to the rainfall when the simulated typhoon is loaded and the rainfall when the maximum flood depth occurs in history, the flood depth parameters when the typhoon is loaded are estimated. The estimated flood depth is loaded into the typhoon model, and the corresponding water flow speed and water flow direction are loaded into the typhoon model. The flood depth estimation formula is:

[0016] A=C / D×B

[0017] In the formula: A is the estimated flood depth; B is the maximum flood depth in history; C is the rainfall when loading the simulated typhoon; D is the rainfall when the maximum flood depth in history occurs.

[0018] Furthermore, when an earthquake has occurred at the geographical location of the pre-construction building, the historical earthquake parameters with the greatest harm to the geographical location of the pre-construction building are obtained; when no earthquake has occurred at the geographical location of the pre-construction building, and the geographical location of the pre-construction building is between the seismic belts of two adjacent plates, and earthquakes have occurred in other areas of the seismic belt, the historical earthquake parameters with the largest magnitude in the seismic belt are obtained, and the earthquake parameters are loaded on the time period with the largest wind speed in the typhoon model.

DETAILED DESCRIPTION

[0031] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0032] See also Figures 1 to 3 The present invention provides a simulated building wind resistance test device and test method, comprising the following steps:

[0033] S1. Obtain soil hardness and soil at the geographical location of the pre-construction building 12, and construct a typhoon model, wherein the typhoon model includes multiple groups of typhoon hazard parameters, each group of typhoon hazard parameters corresponds to a single simulated typhoon, and each group of typhoon hazard parameters includes wind speed, wind direction and rainfall loaded in time sequence;

[0034] S2, compacting the collected soil into base soil 3 according to the soil hardness, constructing a base 10 on the base soil 3, and constructing a building 12 on the base 10, the base 10 and the building 12 are constructed in equal proportions, and the materials of the building 12 and the base 10 are the same as the construction materials of the pre-built building 12;

[0035] S3, loading the typhoon model and selecting typhoon hazard parameters to conduct a simulation test on the building 12;

[0036] S4. monitoring the stress, deformation, tilt and displacement of the building 12 during the test;

[0037] S5. Generate and display a three-dimensional stereogram based on the real-time detected force, deformation, tilt and displacement of the building 12.

[0038] The present invention compacts the collected soil into a base soil 3 according to the soil hardness, so that the base soil 3 can more realistically imitate the soil of the pre-construction geographical location, construct a base 10 on the base soil 3, and construct a building 12 on the base 10. The base 10 and the building 12 are both constructed in equal proportions, and the materials of the building 12 and the base 10 are the same as the construction materials of the pre-constructed building 12. Then, a typhoon model is constructed, and multiple groups of typhoon hazard parameters of different wind force levels are set in the typhoon model. During the test, the typhoon level can be selected according to the needs for the test. Each group of typhoon hazard parameters includes wind speed, wind direction and rainfall loaded in a time sequence, so that when the typhoon model is loaded, the building 12 can be tested according to the wind speed, wind direction and rainfall when the real typhoon occurs, which is conducive to improving the validity of the test results;

[0039] Moreover, during the simulation test, the present invention can generate a three-dimensional stereogram of the real-time detected force, deformation, inclination and displacement of the building 12 and display it in real time, which helps to intuitively experience and analyze the force, deformation, inclination and displacement of the building 12 during the test and provide effective intuitive data support for theoretical design.

[0040] Preferably, the step of constructing the typhoon model in step S1 includes:

[0041] S11. Obtain the historical hazard parameters corresponding to all historical typhoons, including the moving route of the eye and the central wind speed, and select the historical hazard parameters with a central wind speed greater than level 12;

[0042] S12, selecting the position of the maximum central wind speed on the moving route and marking it, selecting the eye route along the moving route in chronological order based on the marked point, obtaining the wind speed, wind direction and rainfall generated at the marked point in chronological order when the eye moves along the eye route in chronological order, and setting them as typhoon hazard parameters;

[0043] By screening and processing, multiple groups of wind speeds, wind directions and rainfalls of typhoons with different wind force equal poles and greater hazards are obtained, which is equivalent to building the building 12 at the maximum wind force on the eye of the storm moving route for testing, so that the building 12 can be in a typhoon environment as if it were real, making the typhoon model more realistic.

[0044] Preferably, the duration of the time series is 12 hours before and after the eye of the storm is located at the marked point. Generally, 12 hours before the eye of the storm moves to the marked point or 12 hours after it moves away from the marked point, the wind force at the marked point will be relatively small and has no experimental significance. Therefore, in order to shorten the test time, the other parts of the moving route are deleted.

[0045] Preferably, multiple groups of historical flood parameters that have occurred at the geographical location of the pre-construction building 12 are obtained, and the flood parameters include rainfall, flood depth, water flow direction and water flow speed. The rainfall, flood depth, water flow direction and water flow speed in the same group correspond to a single historical flood that has occurred. The corresponding historical flood parameters are screened out according to the maximum value of the flood depth. According to the rainfall when the simulated typhoon is loaded and the rainfall when the maximum flood depth occurs in history, the flood depth parameter when the typhoon is loaded is estimated. The estimated flood depth is loaded on the time period with the maximum wind speed in the typhoon model, and the corresponding water flow speed and water flow direction are loaded in the typhoon model. The flood depth estimation formula is:

[0046] A=C / D×B

[0047] In the formula: A is the estimated flood depth; B is the maximum flood depth in history; C is the rainfall when the simulated typhoon is loaded; D is the rainfall when the maximum flood depth in history occurs;

[0048] By using the flood parameters that have occurred in the geographical location of the pre-constructed building 12, the flood depth caused by the rainfall during the typhoon simulation test with different wind force levels can be estimated. Since the water flow speed and water flow direction generally have little effect on the flood depth, the estimated flood depth, water flow direction and water flow direction are loaded into the typhoon model for testing, making the simulation test more realistic and more referenceable.

[0049] Preferably, when an earthquake has occurred at the geographical location of the pre-construction building 12, the historical earthquake parameters with the greatest hazard to the geographical location of the pre-construction building 12 are obtained; when no earthquake has occurred at the geographical location of the pre-construction building 12, but the geographical location of the pre-construction building 12 is between the seismic zones of two adjacent plates, and earthquakes have occurred in other areas of the seismic zone, the historical earthquake parameters with the largest magnitude in the seismic zone are obtained, and the earthquake parameters are loaded on the time period with the largest wind speed in the typhoon model, and the historical earthquake parameters include shear wave amplitude parameters, shear wave frequency parameters, longitudinal wave amplitude parameters, and longitudinal wave frequency parameters distributed in time sequence;

[0050] Since the probability of earthquakes occurring in the seismic zone between the two believed plates is relatively high, the probability of earthquakes occurring in the geographical location of the pre-construction building 12 is relatively high. The highest earthquake that has occurred in the seismic zone is loaded into the time period with the largest wind force for fitting. Optionally, when the earthquake occurring in the corresponding seismic zone is lower than magnitude 7.5, the shear wave amplitude parameters, shear wave frequency parameters, longitudinal wave amplitude parameters and longitudinal wave frequency parameters of the 7.5-magnitude earthquake distributed in time series are loaded into the typhoon model. This can strengthen the test conditions for the building 12 and is suitable for the building 12 with higher construction requirements.

[0051] Preferably, in step S4, the sound and sight of each room in the building 12 are also monitored, and the sound and sight are displayed and played externally, so that the sound and scene in the building 12 during the typhoon test can be transmitted to the outside for external playback and display, so that the situation in the building 12 during the typhoon process can be experienced more intuitively, which can effectively provide a design input reference for designing the living environment comfort of the building 12 when a typhoon occurs.
