The double web girder is constructed from two plywood sheets that are secured to wood members at its top and bottom. Each fastener can support 60lb in single shear.

Determine the required spacing, s, of the fasteners needed to support the loading of 2800lb. Assume A is pinned and B is a roller.

Step 1

Support reaction as shown in FBD

Internal Shear force : As shown on shear diagram , V_{max = 1400 lb}

Step 2

Section Properties

Step 3

Shear force: Since we have two shear planes on...
