Seismic Retrofitting of Existing Steel Frames with External BRBs: Pseudo-Dynamic Hybrid Testing and Numerical Parametric Analysis [PDF]

Earthquake Engineering and Structural Dynamics
The use of buckling‐restrained braces (BRBs) is an effective strategy for improving the seismic performance of existing structures. BRBs can be included within existing frames, creating an additional load path and contributing to their strength ...

Seismic Retrofit of Steel Truss Bridge Using Buckling Restrained Damper

Applied Sciences, 2019
Buckling Restrained Bracings (BRBs) are widely used to improve the seismic behavior of buildings. They are employed for bridges as well, but their application in this respect is limited. BRBs can also be used as a function of the individual damper rather

Performance of the Cold-Bending Channel-Angle Buckling-Restrained Brace under Cyclic Loading

Advances in Civil Engineering, 2019
In this study, three restricted cold-bending channel-angle buckling-restrained brace (CCA-BRB) specimens were experimentally characterised by a low-reversed cyclic loading test. Three specimens had steel cores with cruciform cross section.
