The consequences of such differences in behavior is two-fold: the braces selected for some stories are often far stronger than required, while braces in other stories have capacities very close to design targets, and the distribution of design forces in beams and columns are often far different ...
The BRB design upgrades the post-buckling member behavior by restraining the deformation of energy dissipation plate. The high strength of BRB makes the design competitive when applied to engineering practices. However, the extensive procedures to replace the energy dissipation plate is a concern in ...

The seismic behaviors of inverted V-braced frames is that ...
Under earthquake loading, conventional CBFs dissipate energy by yielding and buckling of braces and yielding of gusset plates. This behavior results in significant damage to the CBF after the earthquake and residual lateral drift. A new seismic lateral force resisting system, known as a self-...
Three finite element models of two buckling-restrained braced reinforced concrete frames with the new and traditional gusset connections and a common reinforced concrete frame, were constructed to investigate the effect of different configurations on the structural behavior of the gusset plates and frames...
The gusset plates were evaluated to ensure that any ductile behavior was limited to the members themselves and not the connections. The project incorporated the use of large buckling restrained braces (BRBs) to improve the performance of the bridge during large seismic events. BRBs are simple, ...

However, the complex BRB-to-...
Five concentrically braced frames are tested under displacement-based cyclic loading to evaluate their behavior, lateral drift, load capacity, hysteresis responses, ductility, and stiffness degradation. Connections details include gusset plates welded to the outside shell of steel columns with and without...
