What depth limit must be adhered to for beam or column webs when using SFRM?

• A. 18 inches.
• B. 12 inches.
• C. 10 inches.
• D. 16 inches.

Answer: (D)

The appropriate depth limit for beam or column webs when using Spray-Applied Fire-Resistive Material (SFRM) is 16 inches. This specification is critical in ensuring that the SFRM can provide the necessary level of fire protection without compromising the structural integrity of the beams or columns. SFRM works effectively on structural elements, but its application has design constraints; this depth limit helps to ensure that the material adheres properly and provides uniform coverage. When the depth of the web exceeds this limit, it can lead to application difficulties, challenges in achieving the desired fire resistance rating, and potential issues with the performance of the fireproofing material itself. Observing this 16-inch limitation is crucial for compliance with relevant fire safety codes and standards, ensuring that structures remain adequately protected against fire events while maintaining safety and performance standards in construction practices.
