Establishing a truss design process that progresses seamlessly from start to finish serves as a critical backbone for efficiency and ensures essential quality control measures. While individual processes might vary from designer to designer, here is a sample step-by-step process. Resist the...

An attic truss with 7 feet room height – should it be designed for 20 psf (pounds per square foot), 30 psf, or 40 psf room live load? Per International Residential Code (IRC) Table R301.5, the minimum uniformly distributed live load for uninhabitable attics with limited storage is 20...

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...

In last month’s article, Designing for Resiliency, I present some of my thoughts on how changing the design approach for wood trusses could aid in making future homes more resilient to the types of climate extremes that seem to be ahead of us. Whether you think that climate change is a...

Alpine visits BEDC’s Manila Campus Alpine and Building Engineering and Design Co. (BEDC) have entered into a strategic partnership to provide high-quality, cost-effective, and scalable design services to the component manufacturing industry. BEDC employs degreed civil engineers who must...

Everyone who uses lumber in trusses understands that defects in lumber can impact truss performance in different ways. Some defects are not important but others will affect truss performance and can even cause truss failure. [For all photos, See PDF or View in Full Issue.] In the first photo,...
