According to the NDS, what is the length of a 8d box nail?

Determine the reference withdrawal design value, W, for a smooth shank carbon steel nail or spike with a diameter of 0.312-in. driven into the side grain of a wood member with a specific gravity of 0.53 where the fastener axis is perpendicular to the wood fibers.

A withdrawal connection is fabricated with lag screws and lumber that has a moisture content of 19 percent. The lumber remains below 11 percent while the connection is in service. What wet service factor, CM, should be used?

A single-story wood-frame building is exposed to a wind load of wU = 205 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 9.5 ft. What is the unit shear in the shear walls?

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 = 32 ft, b = 12 ft, and the height of the walls be 9 ft. The walls are sheathed with portland cement plaster. Are the shear walls satisfactory in regard to the maximum shear wall aspect ratio?

A withdrawal connection is fabricated with lag screws 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?

John, a 35-year-old Black father, was recently released from prison after serving a five-year sentence for a non-violent drug offense. While incarcerated, he struggled to maintain a relationship with his 10-year-old son due to the no-touch visit policy and expensive phone calls. Now that he is out, John faces several challenges: he cannot find stable employment due to his criminal record and owes a significant amount in child support arrears that accumulated. At the same time, he was incarcerated and experienced difficulty securing housing. Despite his efforts to reconnect with his son, logistical and financial barriers make it difficult for him to be as present as he wants in his child’s life. Based on John’s situation, which of the following best explains how structural factors constrain Black men’s ability to fulfill their father roles?

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 seismic load of wU = 285 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 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?

Determine the dowel bearing strength for a 3/4-in.-diameter bolt in Yellow Poplar 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 is exposed to a transverse load of wU = 410 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 = 56 ft and b = 30 ft.
