Analytical investigation of buckling restrained braced frame subjected to non-linear static analysis

Abstract

�Abstract— Buckling-Restrained Braces (BRB) is the advanced methods of seismic force-resisting system used in latest building design. The lateral displacement of the structure is minimized by the efficient seismic vibration control system. In Present research, Pushover analysis was done for a six storey 2D frame for unbraced frame, diagonal bracing and the buckling restrained bracing frame using sap2000. The behavior of various constraints used to appraise structural response are lateral displacement, Interstory drift and base shear. The length and the area of yielding core for modeling the exact behavior of BRB are evaluated. Based on the analytical investigation, the results and graphs shows BRB controls the lateral displacement over the unbraced and diagonal braced.
