摘　　要：选取合理的钢筋和混凝土应力—应变曲线、破坏准则和模型参数,利用有限元分析软件ABAQUS建立高强钢筋高强混凝土双肢剪力墙有限元模型,并进行了非线性有限元分析,分析了剪力墙承载能力、变形能力和破坏形态等。有限元分析结果与试验结果中各关键点的应力、位移以及延性系数误差均较小,有限元模型墙体的破坏形态与试验墙体破坏形态一致,吻合较好,验证了ABAQUS有限元模型的合理性和可靠性。基于ABAQUS有限元模型,进行参数分析,分析了轴压比、混凝土强度等级、连梁跨高比、暗柱纵筋配筋率和钢筋强度等参数对高强钢筋高强混凝土双肢剪力墙抗震性能的影响。Appropriate stress-strain curves of reinforcement and concrete,failure criteria and parameters of model are chosen in this paper. Finite element analysis software ABAQUS is used to set up the model of high strength reinforced concrete coupled shear wall to analyze the damage mode,bearing and deformation capacity of the wall. Comparing the results of finite element analysis with test results,they are in good agreement. Errors of all key points of stress,displacement and ductility coefficient are small. The damage mode of the wall is also consistent with that of the test wall,verifying the rationality and reliability of the finite element model based on ABAQUS software. Influences of concrete strength,axial compression ratio,shear span ratio of coupling beam and steel bar strength on the seismic behavior of high strength reinforced concrete coupled shear wall are studied.
