“…Several researchers developed numerous strategies for enhancing and assessing several significant aspects of the behavior of RC beams [4]. However, most of these methods are centered on additives [8][9][10][11][12], partial or complete replacement of basic concrete materials [6], [13][14][15][16][17][18][19][20][21], recycling materials [22][23][24], or research on the size impact of RC beams [5]. On the other hand, modifying the configurations of the typical shear reinforcement of RC beams in terms of inclination and geometry is a new challenge and promising technique for improving RC beam strength [14][15][16][17][18][19][20].…”

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.
