Experimental and Numerical Investigation of Weak-Axis Connected Steel Plate Shear Wall with Non-slotted and Partially Slotted Infill Plates
All Components with H-shaped section are widely used in steel structures, in which the connection of beam section to column flange (i.e. weak-axis connection) is inevitable. In order to study the mechanical properties of weak-axis connected steel plate shear walls, a 1/3 scaled steel plate wall specimen was designed and subjected to a cyclic test to investigate the properties of stiffness, strength, ductility and energy dissipation. On the basis of this, the partially slotted steel plate shear wall was proposed. The FE model of the test specimen was developed and verified with the test results by FE software Abaqus. Subsequently, the FE model of the partially slotted steel plate wall was developed to study mechanical properties by comparing it with the test specimen. The analysis results show that the partially slotted infill plate can fully play the tension field and avoid the beam’s in-span bending, which effectively improves the structural ductility and energy consumption. Although the partially slotted infill plate will weaken the lateral resistance, the partially slotted SPSW still accounts for 75% of that one without slots in lateral bearing capacity. Additionally, the ductility of this partially slotted one is up to 5.79, and its equivalent viscous damping ratio reaches 30%.
