Fire-Retardant Treated Lumber Use: Type III-A Buildings

Many factors go into classifying buildings. Each type will have different allowable height, allowable number of stories and allowable area limitations based on the classification. This report will focus on Type III-A building construction using fire retardant treated wood (FRTW).

Fire Retardants and Truss Design - Educational Program

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

Submittal Packages and Jobsite Packages: What Should Be Included?

In order to promote the safe installation of building components including trusses, manufacturers send out a Jobsite Package to the construction site with the truss delivery. These Jobsite Packages include the Truss Submittal Package. The Truss Submittal Package includes the information that if required will be submitted to the Contractor/Building Designer, who if required will submit it to the local building official.

Fire Retardants and Truss Design

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.

Resilient Channel or Hat Channel: Use to Meet the Lateral Restraint/Bracing Requirements of the Bottom Chords of Wood Truss Floor Systems

Minimum top and bottom chord permanent lateral restraint/bracing of structural roof or floor trusses is assumed to be adequate when using code-compliant roof and/or ceiling diaphragms. This lateral restraint/bracing is typically accomplished with code-compliant roof /floor sheathing and fastener spacing and/or code-compliant gypsum ceiling material and fastener spacing or purlins at a given on-center spacing.

Truss Heel Heights and the Energy Code

This report discusses ways of increasing the energy efficiency requirements of the building envelope within the context of the requirements of the 2009, 2012 and 2015 International Residential Code (IRC) and IECC for ceiling insulation and truss heel heights.

Single Membrane Floor Protection Requirements of 2012 IRC Section R501.3 & 2015 IRC Section R302.13

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