摘要
在对带TLD的高层建筑风振响应问题系统研究基础上 ,建立了运动方程 ,用第一振型将主体结构展开 ,针对所得方程为非经典阻尼和非对称结构以及脉动风谱为非有理分式风谱的情况 ,用线性滤波过程生成脉动风谱 ,用复模态理论和扩阶法进行解耦 ,获得了等效风谱对应的以第一振型表示的结构风振响应解析解 .
The random wind-induced response of tall buildings with tuned liquid dampers is studied with dynamic equations established and main structures unfolded through the first mode. Considering the damping is a non-classical damping and the random wind spectrum is an irrational fraction wind spectrum, a random wind spectrum is generated using the linear filtered process, and the dynamic equations are disconnected by the complex mode theory and the expanding rank method. The analytic solution to the wind-induced response is expressed by the first mode and corresponds to the equivalent wind spectrum.
