Abstract
Many studies have shown that the ductility of joints can be increased by transverse reinforcement, whereas the increase in ductility can also be done by the constituent material. The use of steel fiber reinforced concrete (SFRC) began to develop, and SFRC became one of the material developments to overcome the weaknesses of conventional concrete. However, fiber concrete has the disadvantage of reducing workability and setting time. In this research, SFRC is combined with self-compacting concrete (SCC) to become Steel fiber reinforced self-compacting concrete (SFRSCC). SCC is expected to improve the workability of SFRC. This research focuses on the behavior of beam-column connections using steel fiber reinforced self-compacting concrete (SFRSCC). The modeling was analyzed to determine the main parameters of the connection behavior including hysteretic curves, ductility values, stiffness values, crack patters and stress-strain. Modeling was performed using SFRSCC characteristic data, and then validated with secondary data obtained from the literature. Structural modeling refers to research conducted by Alkhatib (2015) and Abusafaga (2022). The structural form analyzed is the exterior column beam connection. The results of the analysis are used to confirm the comparison of the ability and performance of SFRSCC and SCC beam-column connections to see the optimum strength required. Substitution of SCC concrete into SFRSCC was shown to improve ductility and stiffness degradation. The ultimate load on the SCC model during the push phase was 151.29 kN with a displacement of 9.96 mm and in the pull phase the ultimate load was 145.73 kN with a displacement of 9.79 mm. While the ultimate load on the SFRSCC model during the push phase was 221.27 kN with a displacement of 14.79 mm and in the pull phase the ultimate load was 213.8 kN with a displacement of 9.79 mm. ? 2024 by authors, all rights reserved.
