What is the maximum allowable platform deflection between supports when loaded?

The correct choice for maximum allowable platform deflection between supports when loaded is 1/60 of the span. This standard is established to ensure structural integrity and safety in platforms, as excessive deflection can lead to discomfort or even hazards for individuals using the platform.

Deflection limits are critical for evaluating how much a structure bends or sags under load. A limit of 1/60 of the span strikes a balance between structural performance and user experience by minimizing excessive movement or vibrations that might occur with heavier loads. This detail is crucial in construction and engineering fields, as it informs how designs must accommodate load-bearing requirements while maintaining safety and usability.

By adhering to this deflection standard, structures can maintain their serviceability, ensuring they operate effectively under expected loads, which is particularly important in applications where users depend on the stability of platforms, such as in scaffolding or elevated walkways.
