Use the AWC Special Design Provisions for Wind and Seismic, 2015 Edition and ASD procedures to answer the following question.A building with a non-structural interior wall is exposed to a transverse load of w = 205 lb/ft. The roof is sheathed with blocked wood structural panels. Is the diaphragm satisfactory in regard to the maximum diaphragm aspect ratio? Let L = 36 ft, a = 30 ft, b = 6 ft, be = 12 ft, and bi = 4 ft.

A shear connection is fabricated with timber rivets and lumber that has a moisture content of 17 percent. The lumber remains above 22 percent while the connection is in service. What wet service factor, CM, should be used?

A building with a non-structural interior wall and an opening is exposed to a transverse load of w = 295 lb/ft. Assume this load was determined from the load combinations, i.e. do not apply the load combinations to it. What is the collector force at the edge of the opening (point A)? Let L = 54 ft, a = 40 ft, b = 14 ft, be = 40 ft, and bi = 13 ft, bo = 15.5 ft.

Use the AWC Special Design Provisions for Wind and Seismic, 2015 Edition and ASD procedures to answer the following question.A single-story wood-frame building is exposed to a wind load of wU = 385 lb/ft. For simplicity, assume this load was determined from the load combinations, i.e. do not apply the load combinations to it, and that the building has no windows or doors. Let L = 36 ft, b = 22 ft, and the height of the walls be 9 ft. The walls are sheathed with unblocked wood structural panels. Are the shear walls satisfactory in regard to the maximum shear wall aspect ratio?

A single-story wood-frame building with an interior wall is exposed to a wind load of wU = 495 lb/ft. For simplicity, assume this load was determined from the load combinations, i.e. do not apply the load combinations to it, and that the building has no windows or doors. Let L = 32 ft, a = 10 ft, b = 20 ft, and the height of the walls be 8.5 ft. If all of the walls are sheathed in the same manner and the allowable shear load of an anchor bolt parallel to the wall is 1,400 lb, would 4 anchor bolts be sufficient for the interior wall?

Determine the reference withdrawal design value, W, for a smooth shank carbon steel nail or spike with a diameter of 0.244-in. driven into the side grain of a wood member with a specific gravity of 0.56 where the fastener axis is perpendicular to the wood fibers.

Determine the reference withdrawal design value, W, for a smooth shank carbon steel nail or spike with a diameter of 0.113-in. driven into the side grain of a wood member with a specific gravity of 0.68 where the fastener axis is perpendicular to the wood fibers.

Use the AWC Special Design Provisions for Wind and Seismic, 2015 Edition and ASD procedures to answer the following question.A single-story wood-frame building is exposed to a wind load of wU = 220 lb/ft. For simplicity, assume this load was determined from the load combinations, i.e. do not apply the load combinations to it, and that the building has no windows or doors. Let L = 44 ft, b = 30 ft, and the height of the walls be 9.5 ft. The walls are sheathed with 3/8-in.-thick particalboard sheathing and 6d nails spaced every 6 in. around the panel edges. Is this design adequate for the load?

Use the AWC Special Design Provisions for Wind and Seismic, 2015 Edition and ASD procedures to answer the following question.A single-story wood-frame building is exposed to a wind load of wU = 435 lb/ft. For simplicity, assume this load was determined from the load combinations, i.e. do not apply the load combinations to it, and that the building has no windows or doors. Let L = 52 ft, b = 30 ft, and the height of the walls be 8 ft. The walls are sheathed with 15/32-in.-thick Structural I wood structural panels and 10d nails spaced every 6 in. around the panel edges. Is this design adequate for the load?

A single-story wood-frame building is exposed to a wind load of wU = 360 lb/ft. For simplicity, assume this load was determined from the load combinations, i.e. do not apply the load combinations to it, and that the building has no windows or doors. Let L = 36 ft, b = 20 ft, and the height of the walls be 9 ft. What is the unit shear in the shear walls?
