The Influence of Key Design Parameters on the Cyclic Axial Behavior of Innovative Replaceable Buckling Restrained Fuses (RBRFs)

Abstract

ABSTRACT behaviorA detailed parametric study was conducted to determine the influence of the key parameters affecting the cyclic axial of replaceable buckling restrained fuses (RBRFs). These RBRFs are developed for use in damage-resistant moment-resisting connections. A sufficiently low ratio of maximum compressive force to maximum tensile force () at the RBRFs needs to be achieved so that the force transferred to other elements is not excessive. The parameters having a significant influence on this ratio were identified as the ratio of external diameter to fuse diameter and the thickness of the unbonded layer and its shape at the transition zone.
