Fire Codes

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

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.

Quality marks are not substitutes for grade marks—FRTW will include both!

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. 

This presentation provides information and analysis of fire retardant-treated wood and metal plate connected wood truss designs.

This Research Report aims to enhance fire performance and fire safety characteristics through the application of a gypsum wallboard membrane.

A CM in Pennsylvania is taking a proactive approach to dealing with exception four of IRC provision R501.3.

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.

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