Deflection Limits for Floor Trusses

There are circumstances when the deflection requirements for a specific structure that utilizes floor trusses as structural members are questioned. The current residential and commercial building codes provide minimum design requirements for loads and for deflection of structural floor members, which also apply to floor trusses. The building designer may specify more stringent requirements. This research report will focus on manufacturer or trade association deflection requirements for a number of floor topping/covering related products

Ahead of the Curve

When a homeowner asked for the contemporary look of a curved roof without the expense of beam or steel construction, the designer knew the answer was trusses.

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.

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.

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.
