［摘要］新青海大厦工程平面呈细腰布置，存在扭转不规则、凹凸不规则、楼板不连续、竖向尺寸突变等，属于结构抗震超限建筑。采用PKPM和ETABS软件对结构进行了多遇地震下的反应谱分析及弹性时程分析，并针对其结构特点，对关键构件进行性能化设计。

Abstract： The slender-waist-shaped plane of New Qinghai Building results in its plane irregularity as well as its irregularity in torsion floor not contact, the vertical dimension mutation, which make the structure exceed some limits of current code of China. PKPM and ETABS software were adopted in response spectrum and time-procedure analysis under frequent earthquake. The seismic performance design of the key component was be taken according to the characteristics of the structure.

Keywords： out-of-code building； seismic performance design； key component
