Dynamic Elasto-plastic Analysis Of A High-rise Hybrid Structure

摘要

Dynamic elasto-plastic analysis methods can actually indicate the characteristic of structure. This paper is concerned with the seismic performance evaluation of a super high-rise hybrid structure by using nonlinear dynamic procedure (NDP). By reasonable selection of input ground motions, 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 pre-established 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 seismic performance objective.
