ABSTRACT
The replaceable link concept, first suggested by Balut & Gioncu (2003), specifically addresses these drawbacks. Similar to RBS connections, this concept also employs the weakening strategy. Instead of weakening the beam flanges, however, nonlinear links are introduced at the locations of expected inelastic action, resulting in a number of advantages. It allows for independent control of beam stiffness and required strength, resulting in more efficient structures; it allows welding of critical elements to be done in the shop, considerably improving construction quality and reducing erection time; and it allows for quick inspection and replacement of damaged links following a major earthquake, significantly minimizing the disruption time of the structure.
