摘要：
Through the rigid model pressure test, the non-Gaussian feature of the surface wind pressure of the square super high-rise building under the interference state is studied. The parameters IF(interference factor of the number of non-Gaussian measuring points)and Q(the proportion of the number of non-Gaussian measuring points in the total measuring points on the building surface)are given to analyze the influence of the non-Gauss-ian wind pressure on the building surface by interference. Taking tandem and parallel arrangements as an exam-ple, it divides the non-Gaussian area of the disturbed building surface wind pressure under the tandem and paral-lel arrangements and gives the recommended extreme wind load values. The results show that the parameters Q and IF can accurately describe the size of the non-Gaussian area of the disturbed building's surface wind pressure and the extent of the disturbance, and determine the location of the disturbing building when the non-Gaussian surface wind pressure of the disturbed building is most obvious;The disturbing buildings in the tandem arrange-ment and juxtaposition will have varying degrees of impact on the location and the size of the wind pressure non-Gaussian zone on each surface of the disturbed building;Finally, the non-Gaussian feature of the wind pressure on the surface of the disturbed building is considered, and the fitting formula of the maximum negative value of the wind load on the surface of the disturbed building in the tandem and parallel arrangement is given. Hence, the result can provide a reference for the wind-resistant design of such structure. © 2022, Editorial Department of JVMD. All right reserved.
