Abstract: Taking Engineering Complex Building of Jinan University as engineering background，dynamic characteristic analysis，elastic time-history analysis and elastic-plastic time-history analysis were conducted of azimuthally symmetrial twin-tower complex high-rise structure with weak connection, and the connective structure and its supports were studied. Results show that it is difficult to coordinate the deformation of the weak connecting structure and the azimuthally symmetrical twin-tower structure under the action of horizontal seismic force, so it is necessary to conduct envelope calculation and design of the twin-tower structure. The displacement of the sliding bearing of the connector meets the displacement requirements under rare earthquake. The vertical vibration acceleration and natural vibration frequency of the connector meet the requirements of normal use comfort. 

Keywords:complex high-rise building； twin-tower structure； weak connection； sliding bearing; steel corridor
