Building wind and rain effect simulation test device

Abstract

The invention relates to the technical field of wind and rain simulation, in particular to a building wind and rain effect simulation test device. The device comprises a pipe body and a control module. A building model is arranged in the pipe body. A wind simulation module for simulating a natural wind field is arranged at one end of the pipe body, a rain simulation module for simulating rain is arranged on the inner side of the pipe body, a wind pressure sensor and a rain pressure sensor are arranged on the outer surface of the building model, and the wind simulation module, the rain simulation module, the wind pressure sensor and the rain pressure sensor are connected with corresponding pins of the control module. The device has the advantages that the different wind and rain weather conditions in nature can be realized; a rain pressure load effect borne by the surface of a building is applied, the difference of environmental load values borne by the building under the wind and raincombined effect and the pure wind field effect is compared and measured, and an effective test verification device is provided for theoretical research of the wind and rain coupled load effect; and the influence of the external environment on a simulation experiment is reduced by being located in the pipe body.

Description

technical field [0001] The invention relates to the technical field of wind and rain simulation, in particular to a building wind and rain effect simulation test device. Background technique [0002] At present, the research on building wind load is quite mature, but the research on the coupling effect of building wind and rain load is relatively lacking. The existing theoretical analysis shows that in some cases, the effect of rain pressure load is more significant, and the coupling effect of wind and rain load often leads to building damage. main factor. The traditional building wind load measurement only considers the effect of wind, and does not consider the influence of the coupling between the wind field and the rain field when the wind and rain are combined. interference from the external environment. Contents of the invention [0003] In order to compare and test the load difference between the joint action of wind and rain and the single action of pure wind, it ...
