摘　　要：采用基于显式积分的弹塑性动力分析方法,对东北传媒文化广场主楼进行了罕遇地震弹塑性时程分析,以了解在罕遇地震下的结构弹塑性行为,同时研究罕遇地震作用下主要构件的损伤和屈服情况,并对损伤程度做出性能评价,以指导结构施工图设计。结果表明,本工程采用的筒中筒结构形式具有较高的抗震承载力和延性,能够满足"大震不倒"的建筑抗震设防目标。The elasto-plastic time-history analysis of Northeast Media Culture Plaza Building under a rare earthquake was carried out by the elasto-plastic dynamic analysis method base on explicit integration,in order to understand the elastoplastic behavior of this structure when suffering a rare earthquake. In addition,the damaged or yielded state of main structural components was studied,and the degree of damage was evasluated when submitted to rarely earthquakes. Some reasonable suggestions were obtained for engineering design. The result showed that the RC tube in tube structure form applied to this project had a good seismic bearing capacity and ductility which could achieve the third level seismic fortification object of criterion.
