微平面模型在剪力墙结构计算中的应用
|
摘要
在适用于剪力墙结构非线性分析的分层壳墙单元模型基础上,对其中的混凝土本构模型和钢筋本构模型进行讨论,采用一种能较好的模拟混凝土在多轴复杂应力状态下特性的microplane模型和一种能够全面反映钢筋在往复载荷下各种复杂受力特性的钢筋本构模型,分别模拟混凝土和钢筋的力学行为特征.利用所提模型进行实例建模,结果表明,该模型能准确模拟剪力墙在各种受力状态下的单向和往复力学行为,可应用于剪力墙结构的非线性有限元分析计算.
Based on the multi-layer shell element model that is now widely used in the nonlinear analysis for the shear wall structure,different constitutive models of concrete and reinforcement are discussed in this paper.Selected in this discussion were two models:a new constitutive model for concrete,referred as microplane model,which could precisely simulate the nonlinear behaviors of concrete under complicated stress conditions,and a constitutive model for reinforcement,which could accurately modeling the hysteretic behaviors of the reinforcement.Some shear wall tests were analyzed to demonstrate the precision of the proposed model.The analytical results show that the proposed constitutive models for concrete and reinforcement can simulate the nonlinear behaviors of shear wall under different stress conditions and can be used in the nonlinear finite element analysis for shear wall structures.
