【摘要】 剪力墙结构的非线性分析方法主要有静力法、动力时程分析法和侧推分析方法(即Push-over分析方法)。本文用微观有限元模型对带竖缝耗能剪力墙和开洞剪力墙的抗震性能进行了分析。本文的主要内容有以下几个方面： (1)阐述了剪力墙结构非线性有限元分析的基本理论，编制了静力非线性分析的Fortran程序，程序的可靠性通过理论计算与试验结果的对比加以验证，并用该程序分析了带竖缝耗能剪力墙，探讨了耗能剪力墙结构的连梁合理高度问题。 (2)阐述了非线性有限元动力时程分析的基本理论，编制了非线性有限元动力时程分析的程序，对两个十层开洞剪力墙模型进行了分析对比。 (3)对开洞剪力墙进行了Push-over分析，通过与动力时程分析结果的对比，论证了剪力墙结构Push-over分析的可靠性。针对Push-over分析中确定目标位移的复杂性，提出了一种简化分析方法。该简化方法用微观有限元模型代替宏观单元模型，并减少了有限元动力时程分析的计算量。更多还原

【Abstract】 The nonlinear analysis of reinforced concrete shear walls includes static analysis method, time-history analysis method and Push-over analysis method. In this dissertation, the response of reinforced concrete slit shear walls under cyclic loading and reinforced concrete shear walls with large or small opening holes is investigated by using nonlinear finite element analysis method. The main work carried out goes as follows:(1) The principal theory of nonlinear finite element analysis was expatiated and a computer program was developed with FORTRAN Powerststion. The reliability of the FORTRAN program was proved by comparing computed results with experimental results, besides ,by using this program .the appropriate length of shear connections of slit shear walls was investigated .(2) The main principle of time-history analysis theory was expounded in the dissertation and a relevant program was developed which is used in analysis of two ten-layer shear walls models with opening hole.(3) The analysis to the shear walls with opening holes was carried out by using push-over analysis method .By comparing the calculation result of Push-over method with the result of time-history analysis, the reliability of push-over analysis of shear walls was proved. Meanwhile, a simplified method of the roof displacement calculation was presented . By using this analysis method, the quantum can be reduced and the calculation models can be replaced by finite element model.更多还原
