What is the shear value in pounds per square foot for 1/2 inch gypsum board with framing spaced at 16" OC?

The correct answer is: 70

The shear value for 1/2 inch gypsum board with framing spaced at 16 inches on center (OC) is typically reported as 70 pounds per square foot. This shear value is derived from the building codes and standards pertaining to wall assemblies using gypsum board, which provide specified shear capacities depending on the material and spacing of the framing. Gypsum board is often used in construction as a component of shear walls, which are essential for resisting lateral forces such as wind or seismic activity. The capacity of the gypsum board to withstand shear forces is influenced by several factors, including its thickness, the type of fasteners used, and the spacing of framing members. When gypsum board is applied over framing that is spaced at 16 inches OC, it achieves a shear capacity that aligns with that of 70 pounds per square foot. This value is significant for designers and builders to ensure that structures can adequately resist loads and perform safely under various conditions. The other options do not reflect the established values for this configuration, which is why they do not represent the correct shear capacity for the specified gypsum board setup.
