Abstract:An industrial building in Shanghai is a special irregular high-rise building with two connected twin-tower structures. In order to evaluate the structural seismic behavior, the response spectrum analysis, elastic time-history analysis and static elasto-plastic Pushover analysis are carried out for the connected structures. The development of plastic hinge is discussed and the weak areas are found. Strengthening mearures for those areas are presented and the conclusions can be reference for similar projects.

Keywords:connected multi-tower; response spectrum analysis; elastic dynamic analysis;  static elasto-plastic analysis
