This study investigates the structural behavior of indirectly loaded deep reinforced concrete (RC) T-beams. A total of 21deep RC T-beams were divided into three groups according tothe ratio of shear span to effective depth. Beams without web reinforcement were tested under indirect point loading applied via central intersecting members until shear failure. Experimental results indicate that indirectly loaded deep beams can carry additional load after diagonal cracking is initiated. The performance of these beams is associated with 3Dnon-linear finite element analysis that involves discrete reinforcement modeling. This modeling process isperformed using ANSYS 12.1. Appropriate numerical modeling approaches are recommended, experimental load-deflection responses are compared in relation with FEA. The behavior of beams was observed under loading. Ultimate loads, deflection responses, and crack patternsare recorded as well. The numerical modeling results agreed with the test results for the beams.
