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
MSRLPC Streamlines Design Values Comparison with New Online Tool MSR Lumber Producers Council The MSR Lumber Producer Council’s new Design Values Comparison Tool makes it possible for component manufacturers and other lumber buyers to easily build a comparison table based on species, size, and grade that includes design values for both visually graded and machine-graded dimensional...
