How many screws are required to connect steel roof trusses to a load-bearing wall?

The correct answer is: 10

The correct answer indicates that a total of 10 screws is required to securely connect steel roof trusses to a load-bearing wall. This number is derived from industry standards and best practices related to structural integrity and safety. In construction, ensuring that structural elements are adequately fastened is crucial for the stability of the building, especially in load-bearing applications. The specified number of screws is based on factors such as the weight of the truss, the materials being connected, and the potential loads that the connection will bear, including environmental factors like wind and snow. Using the proper number of screws not only helps to ensure a robust connection but also adheres to code regulations that are in place to protect the integrity of the structure. In this context, fewer screws may not provide sufficient holding power, while excessive screws could lead to unnecessary cost and material usage without added benefit. This is why the design often dictates a specific number, in this case, arriving at the conclusion that 10 screws offer the appropriate balance between strength and efficiency for connecting steel trusses to load-bearing walls.
