Shear Resistance Mechanisms on High-Panelized Steel Sheet Walls with Burring Holes

Abstract

<p>High-panelized shear walls containing 3.53–4.53 m long steel sheets with burring holes aligned vertically are applied to large space flat buildings in seismic regions. A configuration with burrs on the inside enables the construction of thinner walls and simplified attachment of finishing. Machining of equipment piping holes can be omitted. The wall that receives the in-plane shear force allows shear stress to concentrate in the intervals between the holes. Finite element analyses and in-plane shear experiments revealed that all intervals between the holes were simultaneously deformed, and buckling areas in the intervals were restricted by the use of ring- shaped ribs of the holes. Post-buckling behavior depended on the shapes of tension field on the intervals. The allowable design strength and indices of strength after buckling were developed.</p>
