ABSTRACT Concentrically Braced Frame (CBF) is one of the commonly used seismic-resisting systems because it can effectively resist lateral forces. However, this system has a weakness, which is the risk of buckling under compressive forces that can reduce the structural capacity. Buckling Restrained Braced Frame (BRBF) is a development of CBF with restrainers that prevent buckling. This fin…
