This article originally appeared in STRUCTURE Magazine and is reprinted with permission. One of the more hotly debated topics in the multi-story wood community is whether wall stud and truss or joist alignment is required over the full height of a building, or whether it is beneficial to...

Many buildings place mechanical equipment—such as air conditioning units, heaters, or ventilation systems—on the roof. These are known as Roof Top Units (RTUs). Installing this equipment on the roof helps save valuable floor space inside the building. RTUs come in a wide range of...

Have you heard the big news? In December, TechWood unveiled two new fire-rated wall assemblies that not only meet IBC/IRC code-compliant fire protection for residential and commercial construction, but exceed code, adding exclusive protections against mold, rot, and termites while stabilizing...

As you’re building your 2026 calendar, be sure to block in time for our next wood construction course sponsored by the Virginia Tech Continuing and Professional Education program. Co-sponsored by the International Code Council, this spring we’re offering “Wood Design, Loads,...

For the first time in U.S. model building code history, tornado design provisions for Risk Category III and IV buildings are given in the 2024 IBC. In fact, John ‘Buddy’ Showalter and Sandra Hyde have an excellent article on this, “2024 IBC Significant Structural Changes...
