What is the maximum length of a penetration allowed in a structural steel member?

A. 3 in.
B. 3.5 in.
C. 4 in.
D. 4.5 in.

The correct answer is: D. 4.5 in.

The permissible maximum length of a penetration in a structural steel member is crucial for maintaining the structural integrity and load-bearing capacity of that member. In this context, the maximum length of 4.5 inches is the correct answer because it aligns with the standard guidelines and engineering practices that ensure structural safety. Penetrations are openings made for various installations such as piping or electrical conduits. Keeping the penetration within the specified limit helps avoid compromising the strength of the structural steel. Exceeding this limit could lead to potential weaknesses or failure points in the structure, particularly under load stress. While other options present shorter maximum lengths, they do not reflect the maximum allowance set by industry standards, which has determined that 4.5 inches is the limit to ensure adequate structural performance while still allowing for necessary functionality. Understanding these limits is essential for contractors and engineers to ensure they comply with building codes and maintain the safety of their projects.
