True or False: Walls of metal-framed buildings are strengthened by diagonal straps or the use of plywood or OSB sheathing at the corners.

The statement is true because diagonal straps, plywood, and oriented strand board (OSB) sheathing are commonly used methods to enhance the structural integrity of metal-framed buildings. These elements provide lateral stability, which is crucial for resisting wind loads and seismic forces.

Diagonal straps help distribute loads across the frame and prevent racking, which can compromise the building's shape. Similarly, the application of plywood or OSB sheathing at the corners contributes to the overall rigidity of the structure. This practice ensures that the building can withstand various environmental stresses, maintaining both safety and structural longevity.

Strengthening walls in this manner is a standard practice in both residential and commercial constructions, thus it is not limited to a specific building type. Understanding these reinforcement techniques is essential for effective print reading and construction practices.
