Abstract: One office building in Chengdu is a 48m large-span conjoined steel truss structure with frame-shear wall structure. Performance based seismic design objectives of the building were proposed with consideration of the project characteristics and out of code conditions. Performance based seismic design and comfort analysis was carried out on the overall structure and large span floor respectively. The calculation results show that the selected structural system is rational, safe and reliable, and all performances of the structure can achieve respected performance based seismic design objectives.

Keywords: large-span conjoined structures; performance based seismic design; dynamic elastic plastic analysis
