Abstract

![CDATA[Fuses or sacrificial elements are the weakest part of a structural member that are designed to localize potential failure within themselves. These elements are used to dissipate the energy of a severe lateral load while preserving the integrity of other components of the structure. This paper presents an innovative Composite Buckling Restrained Fuse (CBRF) as a segment of a bracing element. CBRF is an improvement on the Buckling Restrained Braces (BRBs) with shorter length and different performance in tension and compression. Utilizing tensile-only elements in this fuse with a new configuration improves the efficiency of the energy dissipation and eliminates the limitations of the tensile strength that exist in bracing elements which contain traditional BRB fuses. Two CBRF specimens are designed and tested experimentally under cyclic load. Moreover, a numerical model is developed to provide better insight into the core and encasing performance. The results indicate that the proposed fuse has a ductile behaviour with high energy absorption capability along with a reasonably steady stable hysteretic response.]]
