Distribution Characteristics of Mean Wind Pressure on Tall Buildings

Xie Zhuang-ning Zhu Jian-bo(State Key Laboratory of Subtropical Building Science,South China University of Technology,Guangzhou 510640,Guangdong,China)  
The variation of wind pressure on a super-tall building under the interference of nearby buildings was measured by a series of wind tunnel tests by means of the synchronous pressure measurement technique,and the interference effects of two tall buildings with different breadth ratio Br and height ratio Hr on the wind pressure were analyzed.The results show that(1) the interfering building usually causes obvious shielding effect on the principal building when it is placed in the windward area with an across-wind-direction spacing less than twice the breadth of the principal building,and,generally,wider and higher interfering building may cause more significant shielding effects;(2) due to the three-dimension flow effects,lower upstream interfering buildings(Hr1) in tandem arrangement may increase the local mean wind pressure on the windward and the lateral face by 25% and 56%,respectively;(3) the channeling effect in side-by-side arrangement is the main reason for the wind pressure increase;(4) the maximum interference factor of the wind pressure on the lateral face is found to be 2.6 in side-by-side arrangement and decreases with the increase of building spacing;and(5) the channeling effect tends to disappear only when the building spacing exceeds eight times the breadth of the principal building.In addition,a credible regression equation with the accuracy of 99% for two side-by-side arranged buildings is proposed to predict the maximum interference factor of the mean wind pressure on the lateral face.
