摘　　要： 采用改进的AR法和相应自编程序,模拟出索穹顶屋盖结构各节点的脉动风速时程,将流固耦合作用引入结构的动力平衡方程,进行了结构风振响应时程分析。通过结构典型节点处的位移响应和关键构件的内力响应计算结果的分析,给出结构的位移风振系数和内力风振系数,并与结构风振响应频域分析结果加以对比,得到一些有意义的结果和结论。 Here, by means of the improved AR method, a simulation program for time histories of fluctuating wind velocities at nodes of a cable dome structure was developed and used. The effect of fluid-structure interaction was considered in the dynamic equations of the structure, the time-history analysis for the wind-induced vibration response of the cable dome structure was performed. Through the analysis of computational results for the nodal displacement responses and the internal force responses, the corresponding wind-induced vibration coefficients using the time-domain method were given and compared with those using the frequency-domain method. Then some useful results and conclusions were given.
