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
