Behavior of Beam-Column Joint Self-Compacting Concrete (SCC) Using Steel Fiber 5D under Lateral Cyclic Loading

Steel fiber reinforced self-compacting concrete is a composite material that combines the properties of self-compacting concrete and steel fibers. Self-compacting concrete has the ability to fill any voids in the intended casting location by leveraging the gravitational force exerted by the concrete (Fethi et al., 2020). The concrete mixture employed in this study comprises cement, water, fine aggregate, coarse aggregate, and steel fiber. The steel fiber utilised is 5D hooked-end. This research focuses on the mechanical properties and behavior of interior beam-column joint self-compacting concrete using steel fiber-reinforced 5D (SFRSCC). The modeling was analyzed to determine the main parameters of the connection behavior, including hysteresis curves, ductility values, stiffness values, crack patterns, and stress-strain. By including steel fiber, the properties of self-compacting concrete are intended to enhance the properties of concrete. The results obtained in this research are that the stiffness value for the SCC model is 3.2%, and for the SFRSCC model, it is 4%. The ultimate load for the SCC model is 10.94 KN during the compression phase and 11.2 during the tension phase, while for the SFRSCC model it is 14.769 KN during the compression phase and 15.634 during the tension phase.
