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

Why Fire-Rated Hangers Are Required in Type III Wood-Frame Buildings Paul McEntee One of the first mixed-use designs I worked on as a consulting structural engineer was a four-story wood-frame building over two levels of parking. Designing the main lateral-force-resisting system with plywood shearwalls was a challenge for this project that required new details to meet the... Read More August 2023 Issue #15289 Page 108

The Development of the Truss Plate, Part III: The Ingenuity of Carol Sanford and Cal Jureit Joe Kannapell Carol Sanford’s invention didn’t equal Cal Jureit’s, but he made up for it with his head start and his aggressive marketing. Sanford had filed for his patent in March 1954, two years ahead of Jureit’s September 1956 filing, and had a plate design that was relatively... Read More October 2022 Issue #14279 Page 10
The Development of the Truss Plate, Part II: Cal Jureit’s Invention Joe Kannapell Civil engineer Cal Jureit had moved on from wood structures to concrete foundations, but not completely. While he was engaged with the problem of building houses on Miami’s marshes near the Everglades, he had left the problem of wood connections unresolved. Perhaps his ongoing work on Dade...
