Experimental Study on Wind Load Characteristics Caused by Wind Damage in Vulnerable Areas of Low-rise Building Roofs

Abstract

Through the wind tunnel test on the opening of different locations and local areas in vulnerable areas of low-rise building roofs, the distribution characteristics of wind pressure inside and outside the roof caused by roof damage. The results show that the influence of the wind direction angle on the internal pressure caused by the wind is obvious, and the internal pressure caused by the opening on the leeward surface is small and the change law is obviously different from that on the windward surface. The correlation coefficient on the inner side of the roof opening is higher than that on the side of the unopened roof, and the correlation between wind pressure on the measurement points near the opening is larger than other regions.
