Abstract
A corrugated sheet metal wall sheathing for resisting external excitations such as wind or earthquake of light-framed wall structures. The sheathing has sheet profile proportioned to insure the top flutes deform laterally and yield at the end of the flute before the onset of any failure mode. A transverse slot in included in each top flute and adjacent web of the sheathing and spaced at intervals along the length of the sheathing.
Claims10
Corrugated sheet metal wall sheathing to resist external excitations such as wind or earthquake of light-framed wall structures comprising:
- a sheet profile proportioned to insure the top flutes deform laterally and yield at the end of the flute before the onset of any failure mode;
- and
- a transverse slot in each top flute and adjacent web of the sheathing spaced at intervals along the length of the sheathing.
A structural shear panel comprising:
- a corrugated sheet metal panel extending in a first direction and second direction along a plane, the corrugated sheet metal panel having a plurality of upper flute portions, a plurality of lower flute portions both, and a plurality of web portions interconnecting the upper and lower flute portions, the pluralities of upper flute portions, lower flute portions, and web portions all being elongated along the first direction,
- wherein a first plurality of openings linearly extend along the second direction through the plurality of upper flute portions and through the plurality of webs, but not through the lower flute portions,
- wherein the first plurality of openings are configured such that shear forces applied to the corrugated sheet metal panel cause preferential deformation at the first plurality of openings.
