Shear Resistance Mechanisms on Steel Sheet Shear Walls with Burring Holes and the Effect of Cross-Rails

Abstract:

Steel sheet shear walls are panels in which sheets with burring holes aligned along the vertical direction are fastened to frame members and are applied to multi-story buildings in seismic regions. The wall that receives the in-plane shear force allows shear stress to concentrate in intervals between the burring holes. Finite element analyses and in-plane shear experiments revealed that all intervals between the holes were simultaneously deformed, and buckling areas were limited in the intervals by ring-shaped ribs of the burring holes. The effects of cross-rails are minimal in elastic region. Post-buckling behavior depends on tension fields on the intervals and restraints by cross-rails. The allowable design strength formulas and the indices of strength after buckling are developed.
