摘要
在带转换层高层建筑结构的振动台试验结果和理论分析的基础上,提出了带弹性转换层高层建筑结构的动力分析模型———局部层间弯剪型串联多自由度体系模型,即转换层及其下部结构各层视为层间弯剪型,转换层上部结构各层视为层间剪切模型。转换层视为弹性构件,整个分析过程中均取其等效刚度。分析表明,采用局部层间弯剪型串联多自由度体系模型可较好地模拟带弹性转换层高层建筑结构的弹塑性地震反应。
In order to study the elasto-plastic seismic based on shaking table test and theoretical analysis of response of highrise building structure with transfer highrise building structure with elastic transfer storey, storey, the dynamic analysis models of highrise building structure with elastic transfer storey is established as a multi-degree of freedom structure system with local flexure shear, that is, transfer storey and its lower storey has flexure shear deformation between storeys, the rest storeys have shear deformation between storeys. Transfer storey is considered as elastic member in time-history analysis, its lateral stiffness is taken to be equal to the equivalent stiffness. From study the dynamic analysis model can simulate the elasto-plastic seismic response of highrise building structure with elastic transfer storey.
