( China Construction( Shenzhen) Design International, Shenzhen 518048, China)Abstract: There are some cases out of code about a super lugh-rise building, Excellence Croup Houhai Project, which is a frame-core wall structure with allinclined columns above ground. Objectives and design methods of seismic performance were determined, and then the performance-based seismic analysis of the structure and elements was conducted under frequent earthquake, basic earthquake and rare earthquake. And analysis was taken on the effect of the structure caused by inclined columns. Finally, seisnuc measures were adopted based on results of analysis and structure characteristics. Through a series of performance-based seismic analysis and design, the structure safety is improved and its seismic performance objectives are realized.
Keywords: inclined columns; seismic performance; elastic-plastic; seismic design measures
