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 ineach top flute and adjacent web of the sheathing and spaced at intervals along the length of the sheathing.

1-10. (canceled)
A structural shear panel comprising:
- a corrugated sheet metal panel extending in a horizontal direction and in a vertical direction along a vertical plane, the corrugated sheet metal panel having a plurality of upper flute portions, a plurality of lower flute portions, 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 horizontal direction;
- a first plurality of openings that linearly extend along the vertical direction through the plurality of upper flute portions and through the plurality of web portions, but not through the lower flute portions;
- and
- a second plurality of openings that linearly extend along the vertical direction, parallel to the first plurality of openings, through the plurality of upper flute portions and plurality of web portions, but not through the lower flute portions.
The structural shear panel of claim 1, wherein a graphic depiction of shear forces applied to the corrugated sheet metal panel and resulting deformation comprises a full non-pinched hysteresis loop.
The structural shear panel of claim 1, wherein the first plurality of openings and the second plurality of openings are spaced at an interval that enables a drift ratio of up to 6% in the corrugated sheet metal panel.
The structural shear panel of claim 1, wherein the first plurality of openings and the second plurality of openings are spaced at an interval that enables a drift ratio of 3% to 6% in the corrugated sheet metal panel.
The structural shear panel of claim 1, wherein the first plurality of openings and the second plurality of openings are spaced at an interval that enables a drift ratio of 4.5% to 6% in the corrugated sheet metal panel.
The structural shear panel of claim 1, wherein the first plurality of openings are spaced 16 inches in the horizontal direction from a first vertically-oriented edge of the corrugated sheet metal panel, wherein the second plurality of openings are spaced 16 inches in the horizontal direction from the first plurality of openings, and wherein a second vertically-oriented edge of the corrugated sheet metal panel is spaced 16 inches in the horizontal direction from the second plurality of openings.
The structural shear panel of claim 1, wherein the first plurality of openings are spaced 24 inches in the horizontal direction from a first vertically-oriented edge of the corrugated sheet metal panel, wherein the second plurality of openings are spaced 24 inches in the horizontal direction from the first plurality of openings, and wherein a second vertically-oriented edge of the corrugated sheet metal panel is spaced 24 inches in the horizontal direction from the second plurality of openings.
The structural shear panel of claim 1, wherein a third plurality of openings linearly extend along the vertical direction, parallel to the first and second pluralities of openings, through the plurality of upper flute portions and plurality of web portions, but not through the lower flute portions.
The structural shear panel of claim 1, further comprising:
- a first plurality of fastener openings included in the plurality of lower flute portions, wherein the first plurality of fastener openings are in line with the first plurality of openings, and wherein the first plurality of openings and the first plurality of fastener openings are aligned with a first vertical stud;
- a second plurality of fastener openings included in the plurality of lower flute portions, wherein the second plurality of fastener openings are in line with the second plurality of openings, and wherein the second plurality of openings and the second plurality of fastener openings are aligned with a second vertical stud.
The structural shear panel of claim 1, wherein each opening in the first plurality of openings and the second plurality has the same width, wherein the width is in the range of 1/64 inch to ¼ inch.
The structural shear panel of claim 1, wherein the pluralities of the upper and lower flute portions are orientated 90-100 degrees from the plurality of web portions.
The structural shear panel of claim 1, wherein the corrugated sheet metal panel is 4×8 ft.
A shear wall comprising:
- a plurality of vertical studs;
- a first structural shear panel comprising:
- a corrugated sheet metal panel extending in a horizontal direction and vertical direction along a vertical plane, the corrugated sheet metal panel having a plurality of upper flute portions, a plurality of lower flute portions, 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 horizontal direction;
- a first plurality of openings that linearly extend along the vertical direction through the plurality of upper flute portions and through the plurality of web portions, but not through the lower flute portions;
- and
- a second plurality of openings that linearly extend along the vertical direction, parallel to the first plurality of openings, through the plurality of upper flute portions and plurality of web portions, but not through the lower flute portions;
- and
- a first plurality of fasteners fastening the first structural shear panel to the plurality of studs.
A method comprising:
- forming, from a flat sheet metal panel, a corrugated sheet metal panel extending in a horizontal direction and in a vertical direction along a vertical plane, the corrugated sheet metal panel having a plurality of upper flute portions, a plurality of lower flute portions, 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 horizontal direction;
- and
- forming, on the corrugated sheet metal panel, a plurality of openings that linearly extend along the vertical direction through the plurality of upper flute portions and through the plurality of web portions, but not through the lower flute portions.
