Engineering & Testing

With all aspects of previous data, location planning and weather monitoring decided upon, the final decision to make was how the trusses were going to be set out.The trusses needed to be stored in a way that closely replicates real world conditions.

Heavy rains, high humidity, and large temperature drops at night create a perfect place to store trusses if the goal is to potentially damage trusses from weather exposure. This was the thought process SBCRI followed in order to select locations for the weathering testing program.

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.
