摘　　要：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,然后将各模型计算机程序化,并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。最后利用这一工具,考察了模型对8度区结构在大震下非线性动力反应分析结果的影响。This paper chooses three models-model of Mander, model of Sheikh, model of Park, which express the mechanics capability of confinement concrete perfectly and representatively. The models were programmed and added in the program based on the column-beam element of the fiber model. At last, three models are chosen for dynamic response analysis of simulation structure situated at area of fortification intensity 8.
