Fire Resistance

Use of “L” Type Partition Intersections in Fire-Rated Assemblies

This research report evaluates the use of L-shaped partition intersections as an equivalent alternative to the Ushaped intersections typically shown in fire-resistive assembly evaluation reports.

Put Out the Design Fire Before it Starts

Getting information up front on sprinkler systems can ease the design process.

Determining Fire Resistance

Remember: when you calculate the fire resistance of component assemblies, you have options!
 

Wood Walls Framed for Fire

Since FRTW studs are allowed in wall assemblies that are otherwise defined as non-combustible, building and truss designers often confront the question does a joint between the wall and the roof or floor assembly mean that those elements of the building also require noncombustible material, like FRTW? To answer this, we need to study the IBC

Bottom Chord Live Load Concurrency and Truss Design - Educational Program

This presentation seeks to explain how to correctly apply live loads to the bottom chord of trusses for uninhabitable attics in accordance with IRC Table R301.5 and IBC Table 1607.1 and ASCE 7-10 Table 4-1.

Fire-Retardant Treated Lumber Use: Ceiling Assemblies in Type III Buildings

This report focuses on building code requirements for using fire retardant treated wood (FRTW) in floor/ceiling and roof/ceiling assemblies in Type III building construction. 

Deflection Limits for Floor Trusses - Educational Program

This research report will focus on manufacturer or trade association deflection requirements for a number of floor topping/covering related products where deflection requirements may impact serviceability.

Fire Assemblies: Performance and Application Using Wood Trusses - Educational Program

This presentation provides an overview of fire-rated assemblies that include wood trusses. Topics covered include assembly testing, Harmathy’s rules, and an examination of fire performance in the field.

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.
