Abstract: The ladder-shaped elevation of the south tower of Taiyuan Power Co. Office Building results in its remarkable mass and rigidity eccentricity in plane as well as its irregularity in torsion, which make the structure exceed some limits of current code of China. PKPM and MIDAS softwares were adopted in the response and elastic time-history analysis under frequently occurr and precautionary earthquake. The pushover analysis was carried out with MIDAS to make sure the structure is safe under seldom occurred earthquake. Countermeasures to solve the problems caused by the ladder-shaped elevation and some key techniques in the structure design are illustrated.

Keywords: exceeding code limit; tall building; ladder-shaped building; mass eccentricity; performance objective; Pushover analysis; seismic performance
