Abstract:Partial frame-supported shear wall structure is adopted for the Synonym Haifeng. Performance based seismic design was proposed. Structure and component performance were verified based on bearing capacity and deformation under different levels, including elastic analysis under frequent earthquake, un-yielding and elastic check of structure components under medium earthquake, static and dynamic inelastic analysis under rare earthquake. Series of relevant were suggested to make sure the performance object can be well realized. Besides, wind induced vibration time history analysis was carried out and the analysis results were compared with the results calculated according to the codes, and the unfavorable condition was taken considered in the wind-resistant design.

Keywords:ultra-limit high-rise building; anti-seismic design based on performance; inelastic time history analysis
