Important Quality Checks During Each Stage of Truss Manufacturing

Alpine Team

Quality control starts before the first piece of lumber is set into motion. Every employee at each phase of component design and manufacturing plays a critical role to help avoid costly repairs, potential frustration, and additional workload. As an engineer that has seen many repairs, here are a...

Design Connections: Reducing the Risk of Truss Collapse

Geordie Secord

Last month’s article, Preventing Truss Collapses, talks about some of the job site mistakes that can lead to truss collapses. I have no scientific data to back this up, but it is my belief that all truss collapses could be prevented by following proper lifting methods and bracing of the...

Glenn Traylor

Recently, when a building owner started getting leaks in the roof and noticed unusual variations in the ceiling, I was asked to do an inspection to determine the best way to correct a deflection problem. Upon inspection, it was very evident that the roof trusses had not been installed correctly...

Geordie Secord

Over the many years I’ve worked in the truss business, I’ve had the unfortunate experience of visiting numerous job sites where the trusses have collapsed. Without fail, every one of those collapses has been the direct result of improper bracing, improper hoisting, or a combination...

Bracing on Truss Design Drawings

MiTek Staff

Trusses are designed as individual components to resist the in-plane stresses resulting from the loads applied in the same in-plane direction. To resist out of plane forces, adequate bracing/restraint is required. In absence of designed temporary and permanent bracing plans, BCSI (Building...

All Things Wood: The Enduring Problem of Truss Partition Separation

Frank Woeste

For more than 40 years, truss partition separation, often loosely referred to as “truss uplift,” has been a practical (and annoying) issue for homeowners and homebuilders. While it was first investigated at the field level and researched in the laboratory in the 1970s, an October...
