[摘要] 采用基于顯式積分的彈塑性動力分析方法，對東北傳媒文化廣場主樓進(jìn)行了罕遇地震彈塑性時(shí)程分析，以了解在罕遇地震下的結(jié)構(gòu)彈塑性行為，同時(shí)研究罕遇地震作用下主要構(gòu)件的損傷和屈服情況，并對損傷程度做出性能評價(jià)，以指導(dǎo)結(jié)構(gòu)施工圖設(shè)計(jì)。結(jié)果表明，本工程采用的筒中筒結(jié)構(gòu)形式具有較高的抗震承載力和延性，能夠滿足“大震不倒”的建筑抗震設(shè)防目標(biāo)。

Abstract: In this paper, 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 elasto-plastic 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.
Keywords: ABAQUS; damage; rare earthquake; elastic plastic time-history analysis
