Abstract:
Bracing Systems are usually a set of inclined members that are embedded in structures to resist lateral forces and control lateral displacements. There are different types and behaviors for Bracing Systems depending on the way of assembling and locating them in the structure. Braced Frames, such as Concentrically Braced Frames (CBFs), generally have high stiffness and low ductility. Another Type of Braced Frames is Eccentrically Braced Frames (EBFs) which improves CBFs by establishing suitable ductility as well as stiffness. Inelastic behavior of Links involved with EBFs caused this in EBFs. Nevertheless, these systems have no efficiency in next earthquake, because links are parts of beams and inelastic behavior of them harms beams which are a main part of the structure. So researches are always being in progress to improve this disadvantage of Bracing Systems. In this study, at first we introduce a new kind of Bracing System named Broken Beam Bracing System (BBBS) which may has suitable ductility and high energy absorption capacity. After that we arrange some experiments to obtain how this new System behaves against cyclic loading
