A building with a non-structural interior wall and an opening is exposed to a transverse load of w = 350 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 = 58 ft, a = 40 ft, b = 18 ft, be = 40 ft, and bi = 13 ft, bo = 15.5 ft.

A building with a non-structural interior wall is exposed to a transverse load of w = 210 lb/ft. Assume this load was determined from the load combinations, i.e. do not apply the load combinations to it. What is the roof diaphragm unit shear? Let L = 52 ft, a = 40 ft, b = 12 ft, be = 30 ft, and bi = 10 ft.

Determine the reference withdrawal design value, W, for a smooth shank carbon steel nail or spike with a diameter of 0.12-in. driven into the side grain of a wood member with a specific gravity of 0.50 where the fastener axis is perpendicular to the wood fibers.

Determine the dowel bearing strength for a 5/8-in.-diameter bolt in Yellow Poplar with the load applied parallel to grain.

Determine the dowel bearing strength for a 1/2-in.-diameter bolt in Douglas Fir-Larch with the load applied perpendicular to grain.

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 = 380 lb/ft. The roof is sheathed with single-layer straight lumber sheathing. Is the diaphragm satisfactory in regard to the maximum diaphragm aspect ratio? Let L = 48 ft, a = 40 ft, b = 8 ft, be = 20 ft, and bi = 7 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 = 400 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 = 56 ft, b = 18 ft, and the height of the walls be 9.5 ft. The walls are sheathed with blocked particleboard. Are the shear walls satisfactory in regard to the maximum shear wall aspect ratio?

A building with a non-structural interior wall and an opening is exposed to a transverse load of w = 320 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 = 56 ft, a = 40 ft, b = 16 ft, be = 40 ft, and bi = 13 ft, bo = 15.5 ft.

A building with a non-structural interior wall is exposed to a transverse load of w = 375 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 = 36 ft, a = 30 ft, b = 6 ft, be = 20 ft, and bi = 7 ft.

A withdrawal connection is fabricated with lag screws and lumber that has a moisture content of 21 percent. The lumber remains below 11 percent while the connection is in service. What wet service factor, CM, should be used?
