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.
After the two homes were fully framed and dried-in, the thousands of images collected were analyzed to determine the man-hours it took to complete each discreet framing task and how much waste was generated in the process. The results of the Framing the American Dream study are conclusive: The component-framed house required 152.1 man-hours to complete, whereas the stick-framed house required 373.5 hours. It took two and half-times longer to construct the stick-framed version of the floorplan.
Background:
R501.3 (IRC-12) or R302.13 (IRC-15) states the following – “Floor assemblies….shall be provided with a 1/2-inch (12.7 mm) gypsum wallboard membrane…… or equivalent…….
SBCA has compiled the articles below to provide a comprehensive guide to the information it has published on R501.3 (from the 2012 IRC) and R302.12 (the same language incorporated in the 2015 IRC). The goal in organizing the information in this way is to enable the reader to fully understand this issue and SBCA’s position.
Question: Why was the IRC changed to provide a 2x10 exclusion from the requirement in R501.3/R302.13 that states, “Floor assemblies….shall be provided with a 1/2-inch (12.7 mm) gypsum wallboard membrane”?

At the recent July SBCA Open Quarterly Meeting (OQM) in Madison, WI, the membership discussed the importance of raw material design values and their impact on component manufacturers (CM).
As noted in the following three articles:
The SBCA Truss Plate Council, Executive Committee and Board of Directors have been working on individual sample best practice language for component manufacturers. They are as follows:
SBCA's Design Software policy makes it clear the software and intellectual property should reside in the hands of the CM. Originally passed in 2002, the plate suppliers in attendance (Eagle, Alpine, MiTek and Simpson) all reiterated their unequivocal support for this policy and pledged to continue monitoring the use of its software and resolving instances where the software may be used contrary to this policy.

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