It can be often misunderstood whether a Truss Design Engineer has the responsibility to seal a Truss Placement Diagram (TPD). The purpose of this Research Report is to provide the relevant code sections from the latest editions of the International Residential Code (IRC) for thorough analysis and interpretation. 

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.

The goal of this Research Report is to assist in designing safe buildings economically, especially when sprinkler systems are required or desired in the design.

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.
