Buckling-restrained brace (BRB) is a dual-function device that improves the seismic resistance and energy-dissipation capacity of structures in earthquake engineering. To achieve expected performance under severe ground motions, BRB usually designed to remain elastic mild earthquakes, leading increased forces insignificant vibration-reduction effect on at this stage. This study extends concept ...

In this paper, tests on flexural buckling ( Lateral – Torsional ) of cold-formed steel(CFS) lipped Channel beams under restrained boundary conditions are described Two point loading for flexural tests have been established for 3.0m span to obtain uniform bending moment. The section sizes selected for testing are 100x50x10 mm, 100x50x15 mm and 100x50x20 mm with 1.6mm and 2.0mm thickness for the ...

A buckling-restrained brace (BRB) serves as a typical load-bearing and energy-dissipative device for the passive control of structures under seismic loading. BRB is generally designed to not yield frequently occurring earthquake (FOE) wind loads, resulting in it having less effectiveness vibration reduction compared with post-yielding performance. To address this dilemma, study proposed concept...
