惯性车作用下东方明珠电视塔楼层的动力反应

Dynamic Response Analysis for the Floor of Shanghai TV Tower Subjected to Inertia Car Loads

基于线性结构系统的叠加原理，将游乐惯性车对楼层结构的动力作用采用一系列的冲击荷载来模拟，用有限元方法建立上海东方明珠广播电视塔下球标高８６．３ｍ楼层结构承重体系的三维分析模型，采用振型分析法对在游乐惯性车作用下该楼层结构的动力反应进行了计算与分析，其结果为楼层结构的防振设计提供了理论依据．

In this paper, the dynamic response analysis for the floor of Shanghai TV Tower subjected to inertia car loads is investigated by using finite element procedures. The analysis method is based on the superposition principle of linear structure. The dynamic loads caused by the inertia car are modeled by a series of impulsive load. The dynamic displacement, dynamic stress and the tired strength of the floor structure are given.
