Reinforced concrete (RC) deep beams are critical structural elements used in offshore pile caps, rectangular crosssection water tanks, silo structures, transfer beams in high-rise buildings, and bent caps. As a result of the low shear span ratio to
effective depth (a/d) in deep beams, arch action occurs, which leads to shear failure. Several studies have been carried out to
improve the shear resistance of RC deep beams and avoid brittle fracture behavior in recent years. This study was performed to
investigate the behavior of RC deep beams numerically and experimentally with different reinforcement arrangements. Deep
beams with four different reinforcement arrangements were produced and tested under monotonic static loading in the study's
scope. The horizontal and vertical shear reinforcement members were changed in the test specimens to obtain the effects of
different reinforcement arrangements. However, the rebars used for tension and the vertical shear reinforcement ratio were
constant. In addition, the behavior of each deep beam was obtained numerically with commercial finite element analysis (FEA)
software ABAQUS, and the findings were compared with the experimental results. The results showed that the reinforcements
placed diagonally significantly increased the load-carrying and energy absorption capacities of RC deep beams. Moreover, an
apparent plastic plateau was seen in the load-displacement curves of these test specimens in question (DE-2 and DE-3). This
finding also indicated that diagonally located reinforcements improve displacement ductility. Also, the numerical results showed
that the FEM method could be used to accurately predict RC deep beams' behavior with different reinforcement arrangements.
