摘要
采用ABAQUS建立了高剪跨比榫卯剪力墙的精细化数值分析模型,对比了高剪跨比榫卯剪力墙试验结果与有限元模拟结果,从水平力-位移骨架曲线和墙体破坏形态两方面进行了分析.结果表明:采用库仑-摩擦模型能够准确计算高剪跨比榫卯剪力墙中新旧混凝土结合面间的相互作用,且有限元模拟骨架曲线与试验结果吻合较好,模型破坏特征与试验现象基本一致,可用于参数分析研究.
Abstract
The refined numerical analysis model of mortise-tenon shear wall with high shear span ratio was established by ABAQUS.The test results and finite element simulation results of mortise-tenon shear wall with high shear span ratio were compared,and the horizontal force-displacement skeleton curve and wall failure mode were analyzed.The results show that the Friction model can accurately calculate the interaction between the new and old concrete interface in the mortise-tenon shear wall with high shear span ratio,and the finite element simulation skeleton curve is in good agreement with the test.The failure characteristics of the model are basically consistent with the experimental phenomena,which can be used for parameter analysis.
