Fire Codes

Information On Frt Roof Trusses

Question: 

I need to obtain some information on fire-retardant-treated roof trusses.

Information On Truss Fire Issues

Question: 

I am trying to develop a guideline for my firefighters regarding initial fire attack in buildings with light-weight trusses. My concern is truss failure, especially when exposed to fire. Is there any information on failure time related to flame impingement? Any information about truss failure – especially in a fire condition would be helpful.

Wood Three Hour Fire Assembly

Question: 

Is it possible to construct an assembly for ceiling between first and second floors using 2x with few layers of gypsum to obtain a 3-hour fire rating?

Fire Endurance Calculation for Wood Truss Structural Framing Systems: 2-Hour Assembly

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.

Sprinkler Loads on Trusses - Educational Program

This presentation provides information on and requirements for sprinkler loads on metal plate connected wood trusses.

Sprinkler Systems and Wood Trusses

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.

Fire Resistance Rated Truss Assemblies

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.
