(1 Suzhou Institute of Architectural Design Co., Ltd., Suzhou 215021, China; 2 Efuthquake Engineering Research Center of Nanjing Uruversity of Technology, Nanjing 210009, China)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.
