[摘要] 西交利物浦大学行政信息楼为平面及竖向特别不规则的超限复杂高层结构，采用PERFORM-3D软件进行罕遇地震作用下动力弹塑性时程分析，验证结构是否满足“大震不倒”的设防水准要求，寻找结构薄弱部位，提出相应加强措施；同时，评价结构在大震作用下的力学性能和耗能能力，研究结构关键构件的塑性损伤和屈服情况，并对损伤程度做出性能评价，以指导设计。计算结果表明，在给定的三组地震波罕遇地震作用下，结构具有充分的耗能能力，整体塑性损伤有限，受力性能良好，弹塑性反应及破坏机制符合结构抗震概念设计的要求。

Abstract: Xi' an Jiaotong-Liverpool University's administration&information center is a complex high-rise building beyond the code limits with special irregular in plane and vertical direction. Dynanuc elastic-plastic time lustory analysis under rare earthquake was conducted by software PERFORM-3D,  to verify if the requirement of¨no collapse under severe earthquake" was met. The weak parts of the structure were found out and corresponding strengthening measurements were also given.  Meanwlule, in order to guide the structural design, the mecharucal properly and the energy-consuming capacity of the structure were evaluated, and the plastic damage and yielding status of the key members under the rare earthquakes as well as the evaluation of the degree of the plastic damage were carried out. The calculation results show that under the action of rare earthquake of three given seisnuc wave, the structure possesses sufficient energy-consuming capacity, linuted
plastic damage and good mecharucal performance. Furthermore, the elastic-plastic response and failure mechanism conform to the structural anti-seisnuc concept design requirements.
