DYNAMIC ELASTO-PLASTIC ANALYSIS OF A SUPER HIGH-RISE HYBRID STRUCTURE
Dynamic elasto-plastic analysis methods can actually indicate the characteristic of structure, and it is considered as an accurate method. This paper is concerned with the seismic performance evaluation of a super high-rise hybrid structure on a background of project by using nonlinear dynamic procedure (NDP). By reasonable selection of input ground motions which include three natural earthquake records and a group of artificial waves, and based on some assumptions and considerations, the nonlinear dynamic analyses are carried out by using CANNY program. Then the seismic responses of hybrid structure under three different earthquake intensities are obtained. Comparing the responses of three levels with preestablished performance objective, the results show that all responses meet the requirements. At the same time, the inter-storey shear drifts are mentioned to judge the seismic behaviors of hybrid structure. Based on the large amount of structural response information, conclusion can be drawn that the super high-rise hybrid structure achieves the earthquake performance objective.
