For SFRM applied to a beam, what are the dimensions of the web and flange?

When considering spray-applied fire-resistive materials (SFRM) for structural elements such as beams, it's important to adhere to the specified dimensions for effective fire protection. The correct answer reflects common practices and guidelines for beam dimensions in fire protection applications.

In structural engineering, beams often have specific configurations for their webs and flanges which are crucial for understanding how the SFRM will interact with the structural member. The dimensions of 16 inches for the web and 12 inches for the flange are typically chosen to ensure adequate coverage and performance in fire situations. This sizing allows the fireproofing material to be applied effectively, enhancing the beam's fire resistance while ensuring compliance with building codes or industry standards.

Considerations for these dimensions include the structural load the beam must carry, the fire rating required, and the intended application of the SFRM. A web that is wider may impact the amount of material needed, and flanges that are appropriately sized help in achieving even coverage, thus maximizing the fire protection outcome. This specific combination of web and flange dimensions aligns with common standard practices governing spray-applied fireproofing materials in construction.
