| 摘 要： | 本通过上海虹口足球场复杂屋盖结构体系自振特性的分析和独特显示，获得了振型分布很有价值的规律性。体育场屋盖结构体系的风振分析需要考虑多个振型的影响，由结构风振动力的振型分解法，进行了该足球场屋盖体系十阶振型和振型耦合风振动位移响应的分析和研究，得到了各振型影响的规律和结论。对上海虹口足球场屋盖结构，考虑前七阶振型的影响，精度可基本满足结构设计的需要。

| Abstract: | By analyzing the dynanic characteristics of the large cantilevered roof of Hong kou stadium, the distribution of the mode shapes of this structure was obtained. Contribution of the higher mode shapes to wind induced vibration response must be included in the dynamic analysis of the roof structure. Using the SRSS method the dynamic displacement responses considering the effect of the first ten modes were analyzed, and the infucence of different mode shapes was obtained. It was shown that for this roof structure, by including the first seven modes in dynamic calculation, the accuracy can meet the requirement of the structural design. |
