A single-story wood-frame building with an interior wall is exposed to a wind load of wU = 490 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 = 28 ft, a = 9 ft, b = 20 ft, and the height of the walls be 9 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 2,000 lb, would 5 anchor bolts be sufficient for the interior wall?

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 = 305 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 = 48 ft, b = 30 ft, and the height of the walls be 10 ft. Ignoring the effects of gravity loads, what is the net maximum uplift force at the base of the shear walls?

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 = 315 lb/ft. The roof is sheathed with unblocked wood structural panels. Is the diaphragm satisfactory in regard to the maximum diaphragm aspect ratio? Let L = 72 ft, a = 50 ft, b = 22 ft, be = 14 ft, and bi = 5 ft.

A building with a non-structural interior wall is exposed to a transverse load of w = 400 lb/ft. Assume this load was determined from the load combinations, i.e. do not apply the load combinations to it. What is the maximum chord force? Let L = 44 ft, a = 30 ft, b = 14 ft, be = 30 ft, and bi = 10 ft.

Use the AWC Special Design Provisions for Wind and Seismic, 2015 Edition and ASD procedures to answer the following question.A building is exposed to a transverse load of wU = 380 lb/ft due to wind. Assume this load was determined from the ASD load combinations, i.e. do not apply the load combinations to it. The wood structural panel is 7/16-in. thick 24/16 span-rated sheathing blocked. Nails are 8d common and spaced every 6 in. at diaphragm boundaries and all panel edges utilizing a single row of nails. Is this design adequate for the transverse load? Let L = 50 ft and b = 30 ft.
