考虑钢筋锈蚀的震损结构抗震性能评估
|
摘要
提出了考虑钢筋锈蚀的震损结构抗震性能评估方法,分析了钢筋混凝土结构考虑钢筋锈蚀因素及地震作用后结构抗震性能的变化;通过数值算例获得了考虑钢筋锈蚀的震损结构的能力谱曲线,并与完好结构的能力谱曲线进行对比,验证了该方法的有效性及实用性。结果表明:钢筋锈蚀及地震损伤对钢筋混凝土结构抗震性能影响较大,对震损结构进行考虑钢筋锈蚀因素的抗震性能评估是十分必要的。
A method of evaluating the seismic performance of an earthquake damaged structure considering the influence of rebar corrosion was proposed,and the changes in structural seismic performance of the reinforced concrete structure considering rebar corrosion and earthquake action were analyzed.Through a numerical example,the validity and feasibility of this method were verified;then,the capacity spectrum curves of the damaged structure were got,after contrasting this capacity spectrum curves to those of a perfect structure.Results show that there is a great influence caused by earthquake damage and rebar corrosion on the seismic performance of the reinforced concrete structure.The seismic performance evaluation of an earthquake damaged structure considering rebar corrosion is necessary.
