钢筋混凝土框架节点抗震性能研究进展
|
摘要
历次震害表明:在框架结构中,破坏多集中在节点和底层柱等部位。但是,在目前国内外设计规范中,没有对节点抗震性能进行明确的量化规定。通过国内外框架节点的震害实例及节点实验研究成果,总结了影响节点抗震性能的主要因素;对比分析了现有节点设计计算理论、设计方法及节点变形计算方法;给出了钢筋混凝土框架节点计算理论的最新进展。最后,提出了现阶段节点抗震研究需要解决的几个关键问题。
A variety of earthquake disasters present that most of damages to frame structures are aggregated at the joints and at the column bottoms.But according to the temporary design codes,there are no quantified rules for the seismic design of the joints.Based on the examples of the earthquake disasters around world,the main factors which influence the seismic capacity of the joints are analyzed,and the achievements of experiments on the joints are collected in the resent decades.After comparison between the temporary calculated theory of the deformation and the design method of the joints,the latest advances of calculated theory on reinforced concrete frame joints are expressed,then the main problems to research the seismic behavior of the joints are provided in present time.
