With the increasing awareness on the topic of earthquake resistance, efficient, cost-effective, and environmentally friendly solutions in the structural field are on the rise. The purpose of this report is to investigate the Timber Buckling Restrained Brace (TBRB), a new lateral-resisting element made of steel and lumber, applicable in residential and small commercial units. In addition to the TBRBs’ materials being readily available, the braces are easy to manufacture, reducing overall costs of production and transportation. The brace, made partly of wood, has also a low environmental impact when compared to other lateral force resisting elements like concrete shearwalls or steel moment frames. Members made of timber lack experimentations in new applications other than timber shearwalls, which are cost-effective solution only under low lateral force demands and when enough wall length is provided. The TBRB, exploring the combination of steel and a lumber casing, can achieve deformations and load demands in the ductile region of the steel that the timber shearwall can’t.
