Abstract:The podium for Juhe Qitai Commercial Complex in Kunming is a large commercial complex building in high seismic fortification intensity area and it is a  complex structure with irregular torsion, discontinuous floor slab and local irregularity (skip-layer column). It is a special irregular structure. PKPM, ETABS and SAP2000 softwares were used to calculate and analyze the structure under frequent earthquakes, fortification earthquakes and rare earthquakes, and Pushover analysis was carried out on the structure. The calculation results show that the predetermined performance design goals of the structure can be achieved and the safety and seismic performance of the structure can be guaranteed through the calculation and analysis of a variety of software and the adoption of targeted strengthening measures. Finally, the periodic reduction coefficient and composite beam design in the design process of steel structure were discussed.

Keywords:commercial complex; steel frame structure; out-of-code analysis; large span; large cantilever
