Noise control is a common concern for homeowners and construction industry professionals alike. Similar to fire, sound follows the path of least resistance, and proper installation plays a significant role in the effectiveness of an assembly's sound transmission rating and/or fire endurance ratings. The following resources provide more information on fire rated and sound transmission assemblies.
One type of connection used in the manufacture of wood structural building components is the glued finger-joint. The relative newness of structural building components, and of the finger-joints which are used in them, has raised questions about their performance from the perspective of fire safety. This page provides documents and resources which address these questions.

In looking to the future, the SBC Industry Testing Task Group has identified the following areas to consider for the development of test plans:
Repair Types & Methods
Specifically, what are the true capacities or effects of holes in truss members; scabs including nails, screws and nails or screws with glue; gussets (single and double shear) with nails (clinched and non-clinched), screws and nails or screws with glue.
Ply-to-Ply Girder Connections
The National Framers Council will develop standards for framing field operations and management to be used as industry best practices, nationally.
Learn more about the National Framers Council (NFC), Cold-Formed Steel Council (CFSC), Truss Industry Business Council (TIBC) and the Equipment Council.
SBCA offers a number of resources to help draft a truss collapse response plan.

Investing in a standardized, comprehensive safety program minimizes the risks faced by both your employees and your company. SBCA’s customizable template materials, developed specifically for the component industry, can help you implement a consistent, measurable in-plant safety program through education, training and certification.
Floor trusses are the solution to many floor framing challenges presented in today's complex and sophisticated building designs. In addition to the space allowed for mechanical and plumbing runs, floor trusses can reduce framing time, material waste and callbacks.
See the resources below for more information on how to specify, install and brace floor trusses.
BCSI Canada includes Canadian references, installation tolerances aligned with local practices, and design related tables consistent with the Canadian design standard.
Building Designers need to account for the dead and live loads of fire sprinkler systems, in addition to the other load requirements imposed under the model building codes. Truss Designers are responsible for incorporating the additional load from the fire sprinkler systems into the truss design. The information in this Research Report is applicable to both floor and roof systems. Only vertical loads from fire sprinkler systems are discussed; lateral loads, where required, should be evaluated separately by a Registered Design Professional.
This Research Report provides construction details for residential deck ledger attachment to metal plate connected wood truss floor systems. Proper attachment of the deck ledger to the house is critical for ensuring that an “attached” deck is safely and securely supported at this location.

The repair and modification of metal plate connected wood trusses can be a very complicated subject, because each situation must be analyzed individually. This Research Report will give an overview of the fundamental principles behind truss repair that inform the truss designer’s approach in all truss scenarios.
The prescriptive residential energy code requirements found in the 2009, 2012 and 2015 International Residential Code (IRC) include requirements for continuous insulation at foundations in several climate zones. This Research Report discusses the issue of cantilevered sill plates supporting metal plate connected wood trusses installed parallel and perpendicular to the foundation walls where there is a potential for discontinuous planes between the exterior wall above the sill plate and the foundation insulation planes.
This Research Report provides a clear perspective on truss plant quality assurance and third party inspections as they relate to the requirements developed by the International Code Council (ICC) within the International Building Code (IBC) and the International Residential Code (IRC). The same perspective outlined in this Research Report should be applied when discussing how all structural building component third party inspections relate to Chapter 17 special inspection requirements.
A lay-on gable frame is typically connected from the top during truss placement, but after sheathing is installed, this connection is no longer visible for the building inspector to verify. This creates a need for an alternate connection that is visible from below. The goal of this Research Report is to analyze a simple, cost-effective, toe nail connection between the lay-on gable frames and supporting truss system that is visible after sheathing is installed.
Use this handy new resource to quickly find more information about your state's building codes.
How long does it take to frame a house? It depends. The 2015 BCMC Build project is making it possible to answer that question by framing two identical houses side by side. Watch the project's progress via live webcams on the jobsite.
A fire endurance rating may be mandated by code for many of the applications where trusses could be used in floor/ceiling, roof/ceiling or in attic separation applications. This Research Report discusses 5 different methods for determining fire resistance.
ASCE/SEI 7-10, Minimum Design Loads of Buildings and Other Structures, lists two methods for calculating wind pressures: Main Wind Force Resisting System (MWFRS) and Components & Cladding (C&C). This report will provide information to assist the building designer in deciding upon the appropriate analysis method for uplift due to wind loading.
