When a ship hit the Francis Scott Key Bridge in Baltimore, MD, its fate was never in doubt. But that was not the case when a barge hit the Eads Bridge near St. Louis, MO, another steel arched truss bridge. The Key Bridge lost one of its main supports, while the Eads Bridge lost one of its truss...

You’ve likely been inundated with resumes and applications from independent offshore truss designers boasting software proficiency, estimating, takeoff, and design skills. Many highlight their experience with US and Canadian employers, often presenting themselves as part of a team of...

As I write this, I am sitting inside a warm office in Northern Ontario, looking out the window at near blizzard conditions, with heavy snow falling and –35° wind chill. Although it is very unpleasant outside, this isn’t necessarily unusual weather for this location, but what is...

Originally intended as an improvement in lumber manufacturing, most dimensional lumber used for framing has a radius corner created during the planing process. The rounded corner radius is intended to make the lumber easier to handle and can improve the lumber’s performance because sharp...

Over the course of 38+ years in the truss and component business, I’ve had the opportunity to see many unusual approaches to designing single family homes. Some I’ve thought were interesting, some were puzzling, and some were just odd – at least to my eye. Here are some that...

Applying special load conditions to trusses is a tedious, repetitive, and time-consuming task for designers. Without a visual representation of the load in relation to the trusses on a plan, it can be a challenge to position the loads and determine the load magnitudes required for each truss. As...

In “Cost-Saving Measures and Memorable Debacles,” I discussed the problems encountered on a site where the owner was acting as general contractor for his new house build and problems that ensued when an inexperienced framer was tasked with installing a complex truss roof. In that...
