高层建筑结构转换层上下层间侧移角比取值探讨

Discussion on Ratio of Sideway Between the Stories up and down in Transfer Story of High-rise building Structure

由于受转换层上下刚度变化的影响,高层建筑结构在抗震设计时,采用侧移角比综合考虑抗剪刚度和抗弯刚度对层间侧移的影响更为合理。通过实例计算分析,给出了带托柱式转换梁的框架-核心筒结构的转换层上、下层间侧移角比的取值范围建议。

On the seismic design of the high - rise building, Using of sideway ratio is more reasonable than the effects of shear rigidity and bending rigidity in the sideway of stories up and down because of the effects of rigidity variety of stories up and down in wansfer story. Base on the calculation of an example, suggestions on range of sideway ratio of stories up and down in transfer story of framecore tube structure with column supporting transfer beam is obtained.
