Design

This presentation provides information on and requirements for truss repairs.

This presentation provides information on and requirements for sprinkler loads on metal plate connected wood trusses.

For Cascade, gambrel trusses were just one unique aspect of an entirely unusual project

Truss placement diagrams (TPDs) may be one of the more misunderstood documents in our industry. 

What will happen if the plies of a multi-ply girder truss are not fastened together properly? Overloading and, potentially, chord fractures can occur.  

ALSC’s PS 20-15 has fundamentally changed what this grade stamp represents.

Few issues have demanded the attention of the SBCA Board of Directors more over the past five years than the variability of lumber design values. SBCA Legal Counsel Kent Pagel provided guidance to component manufacturers (CMs) on ways to mitigate the potential risk and liability that have arisen in the market as a result of how the lumber industry has chosen to deal with the issue of variable design properties.

  • A quarter of a million people left the housing construction industry from 2002-2012, and many of them have found employment elsewhere.
  • Framers are feeling the effects of this exodus more acutely than most, prompting them to look for creative ways to do more with fewer people.
  • CMs can play a pivotal role in switching framers from sticks to components by offering installation training and expertise to new framing employees.

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.

To what lengths can a truss go? Well, a truss can be designed to span as long as a project requires. Just take a look at the Four Winds Arena, a 20,000 sq. ft. practice riding arena with 90 ft. span trusses designed by A-1 Roof Trusses of Fort Pierce, FL.
  • By conducting its own ASTM E119 floor assembly fire testing, SBCA has the data it needs to effectively fight the controversial IRC Section R501.3 code provision and help preserve CMs’ market share.
  • SBCA has drafted template best practice language CMs should consider using in their TDDs, customer contracts and submittal documents to counter the efforts of the lumber industry to shift liability onto end users.
  • Through Framing the American Dream and WorkForce Development efforts, SBCA is actively engaged in helping CMs successfully navigate today’s labor challenges and grow their businesses.
