摘　　要：在文献[1]的研究基础上,选取约束混凝土模型中具有代表性的3个模型——Mander模型、Sheikh模型以及Park模型,然后将各模型程序化,加入基于纤维模型梁柱单元的三维空间框架非线性动力反应分析程序中,重点考察了模型对8度区结构在中震下非线性动力反应分析结果的影响。This paper chooses three confined models of Mander＇s, Sheikh＇s and Park＇s, which express the mechanical capability of confined concrete perfectly and representatively. These models are incorporated into a three-dimensional nonlinear dynamic response analysis program based on the column-beam cells of the fiber model. They are used to analysis nonlinear dynamic response analysis of simulation structure under intensity eight.
