摘要
对碳纤维布 (CFRP)约束框架柱的底部框架砌体结构进行了非线性有限元动力分析 ,分析中考虑了 CFRP约束混凝土后 ,混凝土物理特性的变化。建立了 CFRP抗震加固底部框架砌体结构地震反应时程分析的方法。最后 ,应用该方法 ,对 CFRP约束的底部框架砌体结构进行了罕遇地震作用下的时程分析。
The hybrid masonry-concrete structures strengthened with CFRP excited by earthquake are studied with nonlinear finite element analytical method. Finite element models are developed to simulate the behavior of hybrid masonry-concrete structures strengthened with CFRP sheets. The time-history analytical method of earthquake response to hybrid masonry-concrete structures strengthened with CFRP is presented. Finally, a 7-floor hybrid masonry-concrete structures strengthened with CFRP excited by El-Centro earthquake is analyzed.
