High rise buildings that are 410 feet tall must have an SFRM bond strength of at least:

High-rise buildings that reach 410 feet in height require a certain level of fireproofing performance to ensure structural integrity in the event of a fire. The bond strength of Sprayed Fire-Resistive Material (SFRM) is a crucial factor, as it must adhere properly to the structural elements to provide the necessary fire resistance.

For buildings of significant height, such as those over 400 feet, the requirement for bond strength is elevated due to the increased demand for safety and the greater potential consequences of a fire event. The specified bond strength of 430 psf aligns with industry standards that take into account the effects of thermal expansion and contraction, potential impact, and other stressors that can affect the performance of fireproofing materials in high-rise applications.

This standard ensures that in the event of a fire, the fireproofing material remains securely attached to the structural components, thus maintaining the integrity of the building and providing critical time for occupants to evacuate and for firefighters to respond effectively.
