Weather resistance performance test

In recent years, extreme weather has occurred frequently, and the impact of wind-driven rain on buildings has continued to intensify. Water seepage and runoff pollution are prone to occur, accelerating material water erosion and the impact of temperature and humidity environments on the durability of roofing materials. At the same time, the impact of extreme rainfall and simultaneous loads on buildings cannot be ignored. It is very necessary to master the distribution rules and characteristics of building wind speed and rain pressure loads for the design of buildings against wind and rain, and to effectively reduce wind and rain disasters. Therefore, through the wind-driven rain simulation test, the anti-wind and rain performance of the building design is further verified to provide important data support for the design.
