Don Allen, P.E., S.E.
In light-framed construction, diagonal X-braced walls can provide excellent lateral resistance in both high-wind and high seismic conditions. This presentation will discuss the mechanics of x-braced systems, why they are different from code-defined shear walls, what special detailing is required in high seismic areas, How to calculate x-brace deflection, and how important it is (or isn’t) to have tight straps. Pictures of field examples will be included, as well as design examples for wind, seismic, and deflection calculations. As of the end of 2023, AISI will no longer be writing standards! This is fine for the recently released 2024 codes, but there will be ramifications for future code years. Things are still in flux, but by November 30 I should have some updated information.
