Floor Trusses

Long Span Truss Installation - Educational Program

This program provides information on the installation of long span trusses. 

Floor Vibration Causes and Control Methods - Educational Program

This program provides information on metal plate connected wood truss floor systems and managing vibrations. 

Sound Transmission in Wood Floor and Roof Trusses

Controlling sound transmission in buildings through wall, floor and ceiling assemblies is important for the comfort level and enjoyment of building occupants as they live, work and play in these buildings. This report aims to explore the methods one can use to reduce sound transmission in assemblies constructed with wood trusses.

Single Membrane Floor Protection - Educational Program

This presentation provides information on the use of gypsum wallboard in single membrane floor protection.

Floor Truss Ribbon Board Load Path

The capacity of a ribbon board and its system through the composite of the ribbon board, floor sheathing and bottom plate of the wall has not been ascertained. In order to provide better guidance, a series of tests were conducted in order to determine the capacity of the ribbon board system.

Fast Foundations Start with Floor Systems

Floor systems are as key to making framing better, faster and more cost effective as wall panels and roof trusses. 

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

Truss Submittal Packages and Jobsite Packages - Educational Program

This presentation provides information on truss submittal packages.

Floor Vibrations Causes and Control Methods

While the perception of floor vibrations is subjective from one person to the next, overall floor systems which exhibit lower deflections and less acceleration from vibration sources tend to be perceived better than other designs. To accomplish this, the designer may elect to do one or a combination of things, covered in this report.

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.
