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.
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.
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.
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.

Addressing Product Innovation, Code Approval and Professional Engineering
The “alternative materials, designs or methods of construction,” found in the building code are often misunderstood, leading to the statement: “I need an ICC report.”
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.
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).

Code compliant use of Metal Plate Connected Wood Trusses (MPCWT) to support brick veneer can be accomplished by both individual designs and by adhering to the recommendations that follow within this report. This discussion focuses on a common use of MPCWT’s; the gable end at the transition from a wider section of a building to a narrower section.

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
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.
Component manufacturers who dedicate time and effort into developing a systematic, ongoing process for outreach and recruitment insist it’s more than worth the investment! While there isn’t one right way to find, assess, and grow new talent, read about approaches to workforce development.
Investing in continuing education can be a powerful way to communicate to your existing employees their value to your organization, as well as improve their existing skills.
Learn about component manufacturers taking a proactive approach to their workforce development needs in past SBC Magazine articles and SBCA webinars.
This presentation provides information on recent fire testing of floor systems in an effort to discuss 2012 IRC Section R501.3 and 2015 IRC Section R302.13 and the use of gypsum wallboard in single membrane floor protection.

The truss industry is currently employing ASCE as its source for the loading of live loads to the bottom chord of trusses for uninhabitable attics, in accordance with the International Residential Code and the International Building Code. However, there currently is a discrepancy between ASCE 7, the IBC and the IRC. This report examines the discrepancy and the correct loading for proper truss design.

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.
