A concentrated load of how many pounds is required for a guard's design strength?

The design strength for a guardrail typically adheres to guidelines set forth by safety standards and structural codes, which often require a minimum concentrated load to ensure the system can withstand forces that might be applied during regular use. A concentrated load of 200 pounds is a common requirement established in various building codes, ensuring that guardrails provide adequate safety for individuals leaning or applying force against them.

This load expectation also incorporates considerations for dynamic forces that may occur, such as people leaning against the railing or accidental impacts. The figure of 200 pounds is specifically chosen because it aligns with practical scenarios in residential and commercial settings, enforcing a level of safety that prevents structural failure in real-world conditions.

Understanding this requirement is critical for inspectors as they assess the construction and compliance of guard systems, ensuring they meet or exceed safety standards that protect occupants.
