Hybrid braced frame with buckling-restrained and strong braces to mitigate soft story

Experimental Study of Maintenance-Free Steel-Composite Buckling Restrained Braces

“…Under the same displacement loading, the compressive load is slightly higher than the tensile load. The main reasons can be concluded as follows: 1 First, it is influenced by the transverse expansion of the steel core due to compression, the extrusion of the unbonded silica gel and GFRP, and the friction when relative sliding occurs. 2 Second, when the specimen is under pressure, the lateral expansion of the steel core is limited by the GFRP restraint mechanism, so that the steel core is in a three-dimensional stress state, resulting in a slightly higher compressive load than the tensile load under the same level of loading.…”

“…The application of BRBs to high-rise buildings can effectively control the displacement, and can achieve a good vibration reduction effect. The application of BRBs to the vibration reduction design of bridge structures can provide a new way to solve the vibration reduction design of high-rise buildings under rare earthquakes [1][2][3][4][5].…”

Evaluating the effect of Buckling-Restrained Braces in Steel Buildings against Progressive failure using Different Simulation Strategies

“…Extensive studies have been conducted on progressive failure [1][2][3][4][5][6] and BRBs [7][8][9][10]. Each of them examines a part of this event.…”
