Analysis the Behavior of Deep Beam by ABAQUS

Reinforced concrete (RC) deep beams are one of the most common types in civil buildings in Vietnam, especially in high-rise buildings for the transfer beams. For the deep beam, the assumption of a flat cross-section, the related equation for calculation are not suitable and the stress diagram is not linear. This leads to differences in calculation and design compared to regular beams. Making clearly the behavior of deep beams and the differences with the regular beams is necessary. Nowadays, the analysis of deep beam is conducted based on two cases: (1) span-to-beam depth ratio L/h; (2) shear span-to-beam depth ratio a/h. However, these values differ according to different standards. This paper investigated many different cases of span/beam depth ratio corresponding to two cases of load position. The results show that the definition of deep beam using the span-to-beam depth ratio according to Eurocode standard and the shear span-to-beam depth ratio according to ACI 318 is suitable.
