该文对带五种被动减振器的高层建筑的随机风振响应和等效静态设计风载取值进行了研究。针对目前已有的设置五种被动控制高层建筑用第一振型展开所获得的统一非经典的结构运动方程,该文用复模态法解耦,用随机振动方法获得结构风振响应解析式,并建立将结构分解为系列等效单自由度体系方法,继而利用等效单自由度体系随机风振响应的解析解,获得了带五种被动减振器的高层建筑基于现行规范Davenport谱对应的以第一振型表示的结构随机风振响应和等效静态设计风载取值的解析解。
In this paper, the random wind-induced vibration response and equivalent static design wind load of high-rise buildings with five kinds of passive vibration absorbers are studied. In view of the existing unified non-classical structural equation of motion obtained by the first mode of five types of passive control high-rise buildings, this paper uses the complex mode method to decouple the structural vibration response of the structure with random vibration Then the method of decomposing the structure into a series of equivalent one-degree-of-freedom systems is established, and then the analytical solution of stochastic wind-induced vibration response of an equivalent one-degree-of-freedom system is obtained. Based on the Davenport spectrum corresponding to the current standard, The analytic solution of random wind vibration response and equivalent static design wind load value of the structure represented by the first mode shape.
