【摘要】 基于OpenSees开源软件平台,采用Tcl语言编制了钢-混凝土组合梁纤维截面函数,结合基于纤维截面的非线性梁柱单元,集成了钢-混凝土组合梁纤维模型,可用于完全剪力连接的钢-混凝土组合梁构件及结构在竖向荷载及水平往复荷载作用下的整体弹塑性分析。与国内外大量试验结果的对比表明,所提钢-混凝土组合梁纤维模型具有较高的精度和较为广泛的适用性。更多还原

【Abstract】 On the basis of OpenSees platform,the section function of steel-concrete composite beam fibre was compiled by use of Tcl Language.Combinig with nonlinear beam-column element besed on fibre section,the steel-concrete composite beam fibre model was integrated.The model can be used for elastoplastic analysis of steel-concrete composite beam components connected wholly by shear force and whole structure under action of vertical load and horizontal cyclic load.The comparison with a large number of test results published at home and abroad shows that the steel-concrete composite beam fibre model has more high accuracy and extensive applicability.更多还原
