Timber Buckling Restrained Brace, Faith Sharp, Armando Castaneda Jr
Architectural Engineering
The timber buckling-restrained brace (TBRB) experiment at California Polytechnic State University, San Luis Obispo (Cal Poly), began in 2018 with the goal of finding whether timber may provide proper restraint against buckling of a steel brace. The TBRB was motivated by the limited lateral force resisting systems (LFRS) available for low-to-mid-rise, type V construction; this system would provide strength and ductility at a scale and level of cost appropriate to timber construction.
Early research consisted of uniaxial component testing, where researchers played with the balance between the core brace design and utilization of timber casings for buckling restraint, with minimal …
