摘要
对粘钢抗震加固受损混凝土框架结构进行了非线性有限元动力分析,分析中考虑了混凝土开裂后切向刚度的折减。建立了加固受损粘钢混凝土框架结构地震反应时程分析的方法;应用建立的方法,对粘钢加固受损钢筋混凝土框架结构进行了在罕遇地震作用下的时程分析,并对计算结果进行了讨论。
The RC frame strengthened with steel plate in the case of reforcing excited by earthquake are studied with nonlinear finite element analytical method. Finite element method models are developed to simulate the behavior of RC structures strengthened with externally bonded steel plate sheets in case of reforcing. The time-history analytical method of earthquake response for reinforced concrete frame structures strengthened with steel plate is presented. Finally, a 10-floor RC frame strengthened with steel plate excited by El-centro earthquake are analyzed.
