Abstract:Based on the real project of complex and composite building which exceeds-code limits, the detailed illustration of its structural system concerning concept design, performance design and joint design were presented. Analysis with finite element method(FEM) was conducted to evaluate the anti-seismic property of the structure and the interaction between the steel and concrete. FEM was also applied for the mechanical property of the connecting portion and strength of the joints as well. The detail of construction, as a measure to guarantee the security, had been implemented in the structure. Calculation results show that the anti-seismic capability of the complex and composite building which exceeds the limits with a proper arrangement of structure and appropriate detailing can satisfy the requirements of standard specification.

Keywords:exceed-code limits; complex and composite building；performance design； elasto-plastic analysis；connection strength analysis
