Seismic Behavior Analysis Of Steel Fiber Reinforced Concrete Composite Shear Wall With Double Steel Plates

In view of the lack of in-depth study on the new type of steel-fiber-reinforced concrete shear wall with double steel plates,it is necessary to study the seismic performance of this new type of component.Based on ABAQUS finite element software,a double-steel-filled steel fiber reinforced concrete composite shear wall model was established and its finite element simulation analysis was carried out to study its seismic performance.The content of this article mainly includes the following points:In order to verify the feasibility and rationality of using ABAQUS to simulate the seismic performance of steel fiber reinforced concrete composite shear wall structure in double steel plate,this paper uses ABAQUS to establish the same finite element model as the shear wall test piece in the existing test.Under the same force condition,the initial stiffness,yield load and peak bearing capacity of the finite element model and the experimental model are within the acceptable range.Therefore,it is considered that ABAQUS is used to simulate the double-steel-filled steel fiber reinforced concrete composite shear wall for earthquake ?The finite element model of steel fiber reinforced concrete composite shear wall with double steel plates was established by using ABAQUS software.The numerical simulation was carried out.The steel fiber volume ratio,axial compression ratio and shear span ratio were considered.The impact of the seismic performance of the wall.By studying the hysteresis curve,skeleton curve,bearing capacity ch aracteristic value,deformation characteristic value,ductility,stiffness degradation curve and energy consumption curve,the influence law of each parameter on the bearing capacity,deformation capacity and energy.
