Wind tunnel test study on the wind pressure coefficient of claddings of high-rise buildings

Abstract

The area-averaged most unfavorable wind pressure coefficients (MUWPCs) on various regions of building surfaces and the influence of the side ratio and the terrain category were studied based on wind tunnel test data of scale models of typical high-rise buildings with rectangular cross-sections. The negative area-averaged MUWPCs in the middle-height edge areas generally increased with an increasing D/B side ratio. The area-averaged MUWPCs can be well fitted with a function of the average area reduced by the square of the building depth, D². In addition, no unique pattern was found for the effect of the terrain category on the MUWPCs.

Keywords
