Geordie Secord 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... Read More January 2024 Issue #16294 Page 80
Developing High-Capacity Tension Straps for Mass Timber Engineering Paul McEntee Mass timber buildings use cross-laminated timber (CLT) or mass plywood panels to create horizontal diaphragms to transfer wind and seismic forces into the vertical elements of the lateral-force-resisting system. Spline connections resist shear forces at the panel joints, which I discussed in... Read More January 2024 Issue #16294 Page 100
Floor Truss Technology, Part VII: The Devil is in Those Details Joe Kannapell Building intricate floor truss details may bedevil a robot, but they provide the inherent advantage of floor trusses over I-joists. There are also things that floor trusses can do that I-joists cannot. And they facilitate the most efficient use of materials. Visiting an I-joist cut-off yard...
