摘要
本文研究了高层建筑结构和风作用的耦合振动响应,得到一个具有气体粘性的惯性力项和高阶的风速波动项的非线性微分方程组,应用简易的Park差分法求解,分析了影响结构风振响应的主要因素。获得了具有较好参考价值的风振响应分析资料。
The paper deals with coupling dynamic response of tall building and wind effect. A set of nonlinear differential equations with inertia term of gas viscosity and fluctuation term of wind speed has been obtained. Applying the simple Park difference method to solve the nonlinear equations. some significant data for analyzing coupling dynamic response of tall building and wind effect have been reported. Based upon the calculation , the paper also illus-tates the main effects of wind induced dynamic response for tall building.
