Nonlinear Static and Dynamic Seismic Analysis of a Hybrid High- Rise Structure with Experimental Verification

The prototype hybrid high-rise structure is special for its dual structural systems, so a 1/50 shaking table model was tested by the State Key Laboratory of Disaster Reduction in Civil Engineering of Tongji University to study its seismic behaviors. Then numerical models were made by 3D finite element analysis software, named MIDAS. The comparison of the analytical and experimental results verified the finite element models. In this paper, firstly, a higher structure of the same structure system was designed according to the prototype structure. Secondly, nonlinear static and dynamic analysis was carried out respectively with MIDAS to study the seismic behaviors of the higher structure. Finally, the results of the static and dynamic analysis were compared. It is found that the differences between them are acceptable and reasonable, and the nonlinear static pushover analysis and dynamic analysis are all suitable for the seismic study of this kind of structures.
