Development and experimental validation of self-centering buckling-restrained braces with shape memory alloy
… behavior and performance of self-centering buckling-restrained braces (SC-BRBs) using shape memory alloys (SMAs) is investigated. The SC-BRBs consist of a typical BRB component, which provides energy dissipation, and pre-tensioned superelastic NiTi shape memory alloy rods, which provide …

Nonlinear Finite Element Modelling of Reinforced Concrete Frames Retrofitted with Shape Memory Alloy Buckling Restrained Braces
… research aims to investigate the benefits of Buckling-Restrained Braces (BRBs) as a retrofit technique for accommodating seismic demands in seismically deficient reinforced concrete frames, the dominant structural system of pre-1970s construction. The efficiency of Superelastic-Shape Memory …

A performance based approach for seismic design with hysteretic dampers
… damage due to strong ground motion is the use of buckling restrained braces that dissipate energy by hysteretic behavior. Research conducted in the past reveals that devices such as The Unbonded Brace (TM) provide stiffness and damping to the structure, two key parameters that characterize a …

Buckling-Restrained Braced Frame Connection Design and Testing
… designed, the beam-column-brace connections of buckling-restrained braced steel frames have undesirable failure modes that compromise the integrity and performance of the frames and are costly to repair. To decrease the time and resources needed to repair the frames following an earthquake, a …

Performance Assessment of Seismic Resistant Steel Structures
… study, two innovative systems, which are hybrid buckling restrained braces and collapse prevention systems, are compared to their traditional counterparts using a combination of the FEMA P-695 and FEMA P-58 methodologies. Additionally, an innovative modeling assumption is investigated, where …
