When must steel framing members be replaced or designed specially regarding holes in the web?

40% of the flat width
50% of the flat width
60% of the flat width
70% of the flat width

The correct answer is: 50% of the flat width

Steel framing members must be replaced or designed specially when holes in the web exceed 50% of the flat width. This is based on structural engineering principles that consider the structural integrity of steel members when subjected to loads. Holes create points of weakness that can compromise the member's ability to carry its intended load. When perforations occur, the remaining structural material must still be able to maintain the strength and stiffness required for safety and performance. As a guideline, if the total area of holes reaches or exceeds this critical threshold of 50%, it indicates that the member may no longer perform structurally as intended and thus warrants replacement or redesign. Maintaining structural integrity is crucial in construction, as it ensures safety and compliance with building codes. Therefore, adhering to this standard is essential for the performance and durability of steel framing systems.
