Abstract:The Second Phase Project for Poly International Plaza is a frame-shear wall out-of-code structure with mega conversion truss. Four shear wall tubes are disposed along the periphery of the structure. Mega conversion truss is located in the third structural floor and the steel plates are set in shear walls of the second, the third and fourth structural floors to form steel plate shear wall structural system. The structural system and design conditions were introduced, and structural mechanism characteristics and out-of-code conditions were illustrated. The structure and opponents were analyzed under wind loads and frequent, fortification and rare earthquakes. Analysis results show that adopted reasonable measures can make structure meet expected seismic fortification goals. The fire protection design of mega steel conversion truss was conducted to determine the mortar thickness.
Keywords:conversion truss; steel plate shear wall； out-of-code analysis; floor stress analysis; fire protection design
