“…It is undesirable for engineers due to its abrupt occurrence with a brittle failure approach [6]. As a result, a significant urge has been made to improve RC beams' strength, which is led by the demand for structural safety [7].…”

“…According to the reviewed literature [7], changing conventional shear reinforcement to spiral and truss systems improves the shear and flexural strengths of RC beams. However, the present designs mostly use continuous rectangular spiral and truss systems, emphasizing the significance of exploring various configurations, inclinations, and spacings to establish the most effective design.…”

This paper uses the finite element simulation to examine the effects of modified stirrups on RC beams. There are seventeen (17) FE models, including various stirrup configurations such as traditional, spiral, and truss systems, as well as advanced modifications, were thoroughly analyzed using Abaqus software to evaluate parameters such as loaddeflection relationship, ductility, strength, failure modes, and crack patterns. Among these models, the BT-X design with a 125 mm spacing inclination of 72.10° demonstrated a remarkable load capacity of 110.856 kN, outperforming BN by 7.637%. Notably, throughout the simulation, the BT-R and BT-X designs were shown to be effective at increasing load-carrying capacity. Stirrup spacing and inclination angles are essential influences on RC beam performance. Specifically, the BT-X 125 design significantly improved flexural capacity and ductility. Furthermore, a uniform failure mode was identified across all models, highlighting the positive effect of modified stirrups on RC beam behavior. These findings highlight the importance of changing the stirrup design and selecting spacing and inclinations to improve RC beam performance.
