Research on the shear bearing capacity of corrugated steel plate shear wall and composite wall

In order to study the failure pattern and mechanical behavior, and to develop shear bearing capacity calculation methods for corrugated steel plate (CSP) shear wall and CSP-composite wall under horizontal loads, 4 corrugated steel plate shear wall and CSP-composite wall specimens were designed and tested under low-cyclic reverse loading. 24 corrugated steel plate shear wall and CSP-composite wall models were simulated using the ABAQUS finite element software. The results show that the corrugated steel plate shear wall has better deformability, the corrugated steel plate can effectively inhibit the development of concrete cracks, and has good bond stress with concrete. The horizontal corrugated steel plate shear wall is likely to develop a plastic hinge at the bottom of the constraining edge member. Corrugated steel plate shear wall and CSP-composite wall has good load bearing capacity, ductility and energy dissipation capacity, and load bearing capacity decreases slowly.ABAQUS finite element software can simulate the test well, the simulation results have good agreement with the test results, the finite element calculation results demonstrate that the shear bearing capacity increases with the increase of the thickness of the corrugated steel plate and the wave angle. In addition, the load bearing capacity of CSP-composite shear wall decreases with the increasing of the shear-span ratio. The lateral bearing capacity of the vertical corrugated steel plate shear wall is basically the same as that of the horizontal corrugated steel plate shear wall. The calculation formula for the bearing capacity of corrugated steel plate shear wall and CSP-composite wall proposed is in good agreement with the test results, and it can serve as a practical reference for design and engineering application in the future. The H-shaped steel column has slight contribution to the load bearing capacity of the CSP-composite shear wall. The vertical corrugated steel plate has a higher shear share ratio than the horizontal corrugated steel plate, and improves the shear bearing capacity of the CSP-composite wall significantly.
