| 摘 要： | 本文对采用巨型框架结构的广州天王中心大厦进行了罕遇地震下的弹塑性时程分析。将整体结构划分为两个子结构，对每一子结构分别采用平面协同模型进行静力弹塑性分析，得到层剪力-层间位移四折线骨架曲线和塑性铰分布。塑性铰分布表明结构符合“强柱弱梁”的原则。将两个子结构用刚性楼板连接，对结构进行罕遇地震下的弹塑性时程分析。计算结果表明，结构能满足大震不倒的设防要求。

| Abstract: | A mega-frame structure, the Tian Wang Center Tower in Guangzhou, Guangdong Province, is analyzed by elastoplastic seismic time-history analysis under major earthquake. Two substructures are adopted. The simplified four broken-line skeletons of story shear to drift are found from the push-over analysis. Also the distributions of hinges are obtained. It is shown that the behavior of the structure accords with the seismic principle of strong-column-weak-beam. Four seismic waves acts on the two substructures, which are connected by rigid floors. Elastoplastic time-history analysis shows that the behavior of the structure is satisfactory and it would not collapse under major earthquake. |
