【摘要】 高层钢混凝土结构采用轻钢结构加层后,加层结构存在质量和刚度的突变,从而影响结构的整体性能。本文以一算例,对加层前后的整体结构用广厦程序建模计算,分析结构的自振周期﹑层间位移﹑地震力等方面对结构的影响。比较两种结构整体性能,计算结果可为该类型结构的抗震设计提供参考。更多还原

【Abstract】 High-rise RC structure using light steel structure after adding storeys,adding storey structure existing mass and stiffness of mutations,which affect the structure of overall performance.This paper takes a numerical example,the adding storeys before and after the whole structure modeling calculation,analysis,dozens of analysis of structure natural vibration period,displacement between floors,seismic forces etc,for the influence of the structure.Comparing the overall performance of two structures,some suggestions are proposed on seismic design of adding storeys.更多还原
