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 final project aims
to analyze and compare the structural performance using CBF and BRBF systems
with X-type bracing configuration. This final project is conducted on a 10-story
steel building located in Palu city. The analysis is carried out linearly using the
response spectrum method, and nonlinearly using pushover and time history
methods. The response spectrum analysis shows that BRBF has a shorter natural
period and lower base shear compared to CBF, and is able to reduce the maximum
displacement by up to 59.1% and the inter-story drift by 32.3%. In the pushover
analysis, the performance point displacement of BRBF is slightly lower than that
of CBF. BRBF also has a higher ultimate capacity, with an increase in base shear
of 53.1% and roof displacement of 27.1%. In the time history analysis, BRBF shows
greater maximum base shear and smaller maximum displacement compared to
CBF. The performance level of both models is life safety. In terms of efficiency,
BRBF results in a lighter structure with material savings of around 7,903.65 kg.
Overall, the use of the BRBF system is proven to be superior in seismic performance
and material efficiency compared to the CBF system.
