Abstract
One of the main requirements of the mechanical behavior of the BRBs under severe earthquake loads is to prevent buckling around until a curved piece of plastic is sufficiently shaped and ductile. This paper presents the results of the finite element analysis of all steel barbed wire bolts that have been proposed. Proposed BRBs have a central section similar to that of the Unbreakable Mechanisms (BRMs). The purpose of this analysis is to perform a parametric investigation of BRBs with different gaps (between core 1 and BRM) and initial defects in order to investigate the overall buckling behavior of braiding. The results of this analysis showed that the bending strength of the BRM can have a significant effect on the buckling behavior of the bracket regardless of the size of the gap. In addition, the lowest Euler buckling ratio of the clamping device to the core tolerance resistance () was proposed for design. This ratio is the main controller of the overall buckling of the BRBs
