为了建立统一的碳纤维(CFRP)布加固钢筋混凝土(RC)柱的抗震性能的评价手段,基于二维有限元分析研究探讨分析模型;对3个CFRP布加固RC柱进行了2D-FEA参数模拟分析,考察了现存的裂缝模型、材料本构关系、混凝土的压缩模型对分析结果的影响.通过分析比较得出,混凝土使用Darwin-Pecknold的等价一轴应变模型能很好地模拟CFRP布加固的RC柱的非线性特性及其强度;而且修正Kent Park模型能够较好地模拟箍筋、CFRP布对混凝土的横向约束作用,同时Darwin的破坏准则可以较好地评价二轴应力下混凝土的破坏过程.通过考察CFRP布加固的RC柱的荷载-变形关系、柱子反弯点和柱脚处混凝土、钢筋和CFRP的应力应变的发展,进一步证实了CFRP布对RC柱的抗震加固十分有效.
