Abstract:The office building in A district of Jinqiao Industrial Service Park(Ⅱ) was designed in the height of 70 meters with a frame-shear wall structural system. It is a two-tower-connected hybrid structure, where the suspended structure in between is 35m long, 15-5m wide. This suspended structure is built from the 8th floor to 15th floor. During the project, the structure was analyzed by software MIDAS Gen and SATWE. An elastic analysis of the structure under frequent earthquakes, and elasto-plastic analyses under fortification and rare earthquakes were carried out for structural performances in different degrees of earthquake. By comparing the mechanical behaviors between two individual towers and the connected hybrid structure, the influence of structural connector on the mechanical behavior of the structure was clarified. The analysis results show that the structure can meet all the standard requests of mechanical performance in building codes while satisfying the requirements of seismic performance.
