摘要
本文扼要介绍了计算机数值模拟钢筋混凝土结构地震反应及破损所涉及的非线性动力分析技术,包括结构振动分析模型的构成,单元分析模型及其恢复力模型的选择,逐步积分法的应用及不平衡力的修正,地震反应的能量表达,典型的非线性动力分析程序等.最后列举了一个结构地震反应数值模拟的实例.
Some techniques of nonlinear dynamic analysis involved in the computer numeric simulation on earthquake performance and damage of R/C structures are discussed briefly, which include the constitution of structural dynamic analysis model, selection of element analysis model and its restoring force model, application of successive integration, revision of unbalanced force, expression for seismic response energy, and the computer programs for nonlinear dynamic analysis. As an example, a simulation of the earthquake response of a real R/C structure is illustrated.
