Performance assessment of novel parallel double-stage yield buckling-restrained braces for seismic hazard mitigation
Original language description
A novel parallel double-stage yield buckling restrained brace (PDY-BRB) is introduced within this investigation. The proposed BRB is characterized by unique detailing that facilitates rapid assembly and reliable mechanical performance while exhibiting substantial adaptability in load resistance, deformability, and energy dissipation capacity to accommodate diverse design criteria. A critical evaluation of high-performance materials is initially undertaken. Subsequently, a detailed configuration of the PDY-BRB and hysteretic behavior is presented. The cyclic performance of the PDY-BRB is subsequently investigated through finite element analysis, encompassing hysteretic response, energy dissipation capacity, re-centering capability, and mechanical indexes. A comprehensive parametric study is then conducted to assess the influence of geometrical characteristics on the cyclic behavior of the PDY-BRB, leading to the development of an improved PDY-BRB (IPDY-BRB). The research is extended to a system-level analysis to evaluate PDY-BRB's and IPDY-BRB's efficacy in seismic control. Findings indicate that the rational design of the PDY-BRB effectively mitigates the structure's peak and residual inter-story drift ratio. A salient advantage of the proposed BRBs over conventional BRBs is their superior control of residual story drift ratios. © 2025 Elsevier Ltd
