Abstract:The 9# building of Jinwan Square is a frame-corewall structure and it belongs to the tall building beyond code limits with 299m height. The characteristic and structural design of the engineering were introduced. Performance-based seismic design was adopted because of height beyond code limits and discontinuous lateral force resisting member. The structure was analyzed with multi-model and several softwares, elastic and elastic-plastic analysis were carried out, and some parts with complex stress was made a check additionally. The weak members could be distinguished on the whole and the strengthening measures were adopted. The results show that the functional state and performance of the structure can meet the design goals of performance and code requirement.

Keywords:tall building; beyond code limits; performance-based seismic design; dynamic elastic-plastic analysis; Perform-3D
