中文摘要:
      为增强双钢板混凝土组合剪力墙抗震性能,在双钢板混凝土组合剪力墙端部钢管引入工字型钢,有效抑制构件端部屈曲。以钢管的截面形式、工字型钢尺寸、剪跨比为主要参数,利用ABAQUS有限元软件设计了18片双钢板混凝土组合剪力墙有限元模型,对其滞回性能、承载能力、耗能能力、变形及延性和刚度退化等抗震性能进行对比研究。研究结果表明:端部加强钢管-双钢板混凝土组合剪力墙的承载能力、延性、刚度退化、耗能能力相比普通钢管-双钢板混凝土组合剪力墙构件均有较大提升。随着剪跨比增大,端部加强构件的峰值荷载、屈服荷载、延性、初始刚度、等效粘滞系数的峰值均有较大提升,钢管暗柱的截面形式和工字型钢的尺寸对构件抗震性能影响不显著,构件AZ22-2.0的抗震性能较为优越。
英文摘要:
      In order to enhance the seismic resistance of double steel plate concrete, I-type steel was introduced to effectively inhibit the end flexion of the component. With the cross-section form of steel pipe, I-shaped steel size and shear span ratio as the main parameters, the finite element model of 18 double steel sheet concrete combined shear wall was designed using ABAQUS finite element software to compare the seismic resistance of hysteresis performance, carrying capacity, energy consumption capacity, deformation and ductility and stiffness degradation. The research results show that the carrying capacity, ductility, stiffness degradation and energy consumption capacity of the terminal reinforced steel pipe-double steel plate concrete combined shear wall are greatly improved compared with the ordinary steel pipe-double steel plate concrete combined shear wall components. With the increase of shear span ratio, the peak load of end reinforcement component, yield load, ductility, initial stiffness and the peak of equivalent viscosity coefficient are greatly improved. The cross section form of steel pipe and dark column and type steel size have no significant impact on the seismic performance of components. Component AZ22-2.0 seismic resistance performance is superior.
