【摘要】 通过建立悬吊质量摆减振体系的一般运动方程,将主体结构按第一振型展开,并针对所得方程为非经典阻尼运动方程,用复模态理论解耦,利用随机振动理论获得结构风振响应的解析式,并将建立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的随机风振响应的解析解,获得了带悬吊质量摆的建筑结构基于Dav-enport谱随机风振响应和等效风荷载取值的解析解.更多还原

【Abstract】 The random wind-induced response and the equivalent static wind action of the buildings with suspended pendulum is studied systematically.The dynamic equations are established at first and the main structure is expanded with respect to the first mode,the complex model method is used to disconnect the equations,the universal method that disassembles the structure into a series of equivalent single degree of freedom systems is established,the precise solution of random wind-induced response and the equivalent static wind action basis on Davenport spectrum of the building with suspended pendulums are obtained.更多还原
