柱网参数对框架核心筒结构抗震性能的影响

摘要

Based on the analysis of the static elastic-plastic performance of a 93. 6-meter-high frame core tube structure,structural behaviors in different column parameters were studied in this article,in order to research the different effects on static elastic-plastic performances of a frame core tube structure when different column parameters are adopted,and an optimized suggestion was given basing on the result. By analyzing the frame core tube’s base shear-top story drift curves,ultimate story-drift angle,distribution of plastic hinge and seismic overturning moment with different column parameters,the seismic performance of the structure was discussed.%为了探究不同柱网尺寸对框架核心筒结构静力弹塑性能的影响，对某一高度为93.6 m的框架核心筒模型进行了静力弹塑性分析，研究了在不同柱网参数下，该框架核心筒结构的受力情况，并且基于所得出的研究数据，给出了优化建议，同时分析了该框架核心筒结构的基底剪力与顶点侧移曲线、极限层间位移角、塑性铰分布以及地震倾覆力矩，探究了采用不同柱网参数时，其抗震性能的差异。
