Abstract: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.
