Fire Resistance

Depending on the type of fire-retardant treatment (FRT) used, materials may require a change in design values and reduction in connector capacity. This report intends on providing a clear perspective of interiror FRT wood used in Truss designs.

Fire endurance ratings may be mandated by code for many assemblies in both floor and roof framing systems. This Research Report discusses methodologies to calculate 2-hour fire endurances of a given assembly.

The goal of this Research Report is to assist in designing safe buildings economically, especially when sprinkler systems are required or desired in the design.

A fire endurance rating may be mandated by code for many of the applications where trusses could be used in floor/ceiling, roof/ceiling or in attic separation applications. This Research Report discusses 5 different methods for determining fire resistance.
