【摘要】 为了研究核心筒厚度对高层混合结构抗震性能的影响,利用同济大学MTS多高层钢结构设计系统,根据钢-混凝土混合结构抗震概念设计原理,采用典型的平面布置形式建立高层混合结构计算模型,计算在不同地震烈度、不同场地土、核心筒厚度不同时结构的最大楼层平均位移、最大层间弹性位移角。绘出不同情况下模型的最大楼层平均位移、最大层间弹性位移角变化曲线。得到核心筒厚度对高层混合结构抗震性能有较大影响,可为工程实用计算提供可靠的理论依据。更多还原

【Abstract】 In order to study the influence of the thickness of tube on the aseismic performance of steel exterior frame-concrete interior tube structure ,based on the theory of concept design of steel-concrete hybrid structure and with the help of the MTS systemof Tongji University ,a computer model of the structure is set up . Moreover it is calculated that the maxi mum average displacement of floors , and the maxi mum flexible displacement angle of interfloors for the structure subjected to different seismic intensities , different sites and different thicknesses of tube .It is plotted that the curves of the changes in the maxi mumaverage displacement of floors ,and the maxi mum flexible displacement angle of interfloors for the model under different conditions . The results show that the thickness of tube has greater influence on the aseismic performance of a tall steel exterior frame-concrete interior tube structure ,which provides a credible theoretic basis for practical calculation of projects .更多还原
