This study presents the numerical method in determining the structural strength of reinforced concrete (RC) deep beams using ANSYS, a commercial finite element analysis software. An investigated RC deep beam with a cross-section of 10 × 30 cm and a standard length according to the IS 456-2000 was employed to analyze the structural behavior. The nonlinear stress–strain relationship of concrete and reinforcement was considered in the numerical models. In this study, concrete and reinforcing bars elements were modeled using the SOLID65 and LINK180 models, respectively. The results of finite element models were then compared with those of experimental results. A trivial difference between those results highlighted the capability of the numerical model in analyzing the structural behavior as well as damage patterns of the RC deep beams. A parametric study was also performed to quantify the effects of different parameters including geometry and material on the variation of the strength of the deep beam. The results of this study showed quite accurately the strength of RC deep beams. The simulation method by ANSYS software helps in predicting the structural strength faster, and saving money compared to testing methods.
