框架-核心筒混合结构基于刚度退化的反应谱设计方法研究
|
摘要
根据型钢混凝土框架试验数据确定型钢混凝土框架的刚度退化模型,结合钢筋混凝土剪力墙和钢筋混凝土框架的刚度变化规律,提出框架-核心筒等双重结构体系可用基于刚度退化反应谱理论进行三阶段抗震设计。在介绍该方法实现步骤等的基础上,通过算例验证该方法的适用性。最后得到框架-核心筒在地震作用下剪力重分布的一些规律,并对框架柱的可能破坏状态进行讨论。
The stiffness degradation model of SRC frame is determined based on the experimental data of a SRC frame.Combined it with the stiffness degradation rule in different deformation phases of RC core wall,and RC frame,it is advised that a "three-stage seismic design" process be adopted in frame-core wall structure design through response spectrum analysis design means based on stiffness degradation.And the realization step of the means is introduced,whose applicability in "dual system" is tested by a calculation illustration.In the end,some rules of the inner force redistribution in frame-core wall structure under earthquake load are introduced,and the possible failure mode of frame column is discussed.
