Engineering & Testing

The QC Committee met last week at the SBCA OQM to discuss progress in the Digital Quality Control program and the testing programs underway that will provide data to support the assessment of plated joint quality per ANSI/TPI 1 Chapter 3. 

Whether it’s trusses left in the yard for too long, or trusses left on the jobsite, weathering is a topic that all component manufacturers encounter in their line of work.

If you are designing to the 2015 International Building Code (IBC) or later, it’s important to take a close look at the allowable load ratings you are referencing for some companies’ connectors and hangers.

As a designer, you may prefer to create a flat "seat cut" at a bottom chord peak joint.

The weathering testing that is taking place and is covered through this series of articles is critical to answer the questions that component manufacturers have about trusses that have been left outside.

Aegis Metal Framing is proud and excited to announce that it has successfully completed the development of an ATFP, blast force CFS truss design tool.

To determine the effects of weather on a truss, SBCRI is working with CMs from around the country to provide data, leading to an improved understanding of trusses exposed to weather.

While there is value in following a good set of best practices like those contained in BCSI, SBCRI is looking to improve the knowledge behind BCSI’s guidelines in a way that only data gathered through testing can do.

Question: What are some challenges when insulating a basement or crawl space with spray foam? Answer: Basements and crawl spaces can benefit greatly from the application of spray polyurethane foam (SPF).

In 2000 and 2004 Alpine undertook a weathering study entitled Durability of Plates, R&D #90-07 dated January 3, 2000 and January 22, 2004. Mr. Stu Lewis provided this report to SBCA to aid SBCA with background information regarding the common notion that truss plates back away from lumber.
