Abstract

A hanger for connecting a structural member to a structural support including a base sized and shaped for receiving the structural member thereon. First and second side panels extend upward from the base. First and second back panels each extend from a respective one of the side panels. First and second top flanges each extend from a respective one of the back panels. An opening in one of said first and second side panels and said first and second back panels is configured to receive a fastener to attach the hanger to one of the structural member and the structural support. A slot is adjacent the opening. An area between the opening and the slot defines a yieldable portion selected to deform at a load that is less than the shear load capacity of the fastener when received through the opening for connecting the hanger to one of the structural member and the structural support.

First claim

What is claimed is:

1. A hanger for connecting a structural member to a structural support using one or more fasteners, the hanger comprising:
a base sized and shaped for receiving the structural member thereon;
first and second side panels extending upward from the base;
first and second back panels, each of the back panels extending from a respective one of the side panels;
an aperture in one of said first and second side panels and said first and second back panels configured to receive one of the fasteners to attach the hanger to one of the structural member and the structural support; and
a slot having a height in a vertical direction and a width in a horizontal direction, the slot being spaced from the aperture by a distance less than a diameter of the aperture in the vertical direction, the height of the slot being less than the diameter of the aperture such that the fasteners are inhibited from being received in the slot, the width of the slot being greater than the diameter of the aperture, the slot and the aperture being shaped and arranged relative to each other to define a yieldable portion of said one of the first and second back panels selected to deform at a load that is less than the shear load capacity of the fastener when received through the aperture for connecting the hanger to the structural support.

2. The hanger of claim 1 , wherein the slot has a different shape than the aperture.

3. The hanger of claim 1 , wherein the yieldable portion is configured to resist between about 75% and about 90% of a shear load capacity of the fastener.

4. The hanger of claim 1 , further comprising apertures in at least one of said first and second side panels and at least one of said first and second back panels, and a slot adjacent each of the apertures, each slot and the adjacent aperture being shaped and arranged relative to each other to define a yieldable portion of at least said one of the first and second side panels and at least one of the first and second back panels selected to deform at a load that is less than the shear load capacity of the fastener when received through the aperture for connecting the hanger to the structural member and the structural support.

5. The hanger of claim 4 , wherein the apertures located in said at least one of the first and second back panels are staggered along a length of said at least one of the first and second back panels.

6. The hanger of claim 4 , wherein the apertures located in said at least one of the first and second side panels are positioned along a common axis extending along said one of the first and second side panels.

7. The hanger of claim 1 , wherein the diameter of the aperture is about 0.18 inches (0.46 cm) and the width of the slot is about 0.375 inches (0.953 cm) and the height of the slot is about 0.125 inches (0.318 cm).

8. The hanger of claim 1 further comprising apertures in the first side panel, the second side panel, the first back panel and the second back panel and a slot adjacent each aperture, each slot and the adjacent aperture being shaped and arranged relative to each other to define a yieldable portion selected to deform at a load that is less than the shear load capacity of the fastener when received through the aperture for connecting the hanger to one of the structural member and the structural support.

9. The hanger of claim 8 wherein the apertures in the first and second side panels are located farther from the base than the adjacent slots, and the apertures in the first and second back panels are located nearer to the base than the adjacent slots.

10. A hanger for connecting a structural member to a structural support using fasteners, the hanger comprising:
a channel-shaped portion comprising a base and side panels extending upward orthogonally from the base, the channel-shaped portion being configured to receive the structural member on the base between the side panels;
back panels extending from respective ones of the side panels in planes that are orthogonal to the side panels and to the base; and
top flanges extending from respective ones of the back panels in planes orthogonal to the back panels and the side panels, the top flanges being configured for attachment to an upwardly facing surface of the structural support;
apertures in the side panels and back flanges, each aperture being configured to receive one of the fasteners to attach the hanger to one of the structural member and the structural support; and
slots having a height in a vertical direction and a width in a horizontal direction, each slot being spaced from respective ones of the apertures by a distance less than a diameter of the respective ones of the apertures in the vertical direction, the height of the slot being less than the diameter of the respective ones of the apertures such that the fasteners are inhibited from being received in the slots, the width of the slot being greater than the diameter of the respective ones of the apertures, the slots having different shapes than the apertures, each slot and the adjacent aperture being shaped and arranged relative to each other to define a yieldable portion selected to deform at a load that is less than the shear load capacity of the fastener when received through the aperture for connecting the hanger to one of the structural member and the structural support.

11. The hanger of claim 10 , wherein the yieldable portions are each configured to resist between about 75% and about 90% of a shear load capacity of the fastener.

12. The hanger of claim 11 , wherein the apertures in each of the back panels are staggered along a length of the back panel.

13. The hanger of claim 12 , wherein the apertures in each of the side panels are positioned along a common axis extending along the side panel.

14. The hanger of claim 10 , wherein the diameter of the aperture is about 0.18 inches (0.46 cm) and the width of the slot is about 0.375 inches (0.953 cm) and the height of the slot is about 0.125 inches (0.318 cm).

15. A method of making a hanger for connecting a structural member to a structural support so as to decrease a difference in shear load carried by fasteners connecting the hanger to the structural member and the structural support, the method comprising:
forming from a blank of sheet metal a channel-shaped portion sized for receiving and supporting the structural member;
forming from the blank of sheet metal back flanges extending from the channel-shaped portion;
forming apertures in the channel-shaped portion and the back flanges;
forming slots having a height in a vertical direction and a width in a horizontal direction, each slot being spaced from each aperture by a distance less than a diameter of the aperture in the vertical direction, the height of the slot being less than the diameter of the respective aperture such that the fasteners are inhibited from being received in the slot, the width of the slot being is greater than the diameter of the respective aperture, each slot and aperture defining a yieldable portion therebetween selected to deform at a load that is less than the shear load capacity of the fastener when received through the aperture for connecting the hanger to one of the structural member and the structural support.
