This project experimentally investigated some of the most common timber bracing systems used in the Australian residential construction market and was one of the world’s largest studies of its kind. The objective of the study was to verify the design capacities of these bracing systems. The study found that plasterboard substantially improves the capacity of timber-framed shear walls and that design values for most systems are conservative; however, some adverse findings of the study relate to systems with sheathing on both sides of the wall, short length walls and cross-braced walls with stud straps.
