Due to characteristic small ratio between shear span and depth, deep beams behave different from shallow ones. The response is characterized by non-linear strain distribution (even in the elastic stage), and a significant direct load transfer from the point of load to supports. Reinforced concrete continuous deep beams are fairly common used in structures. The behavior of continuous deep beam is significantly different than that of simply supported one. The coexistence of high shear and high moment within the interior shear span in continuous beams has a considerable effect on the development of cracks, leading to a significant reduction in the effective strength of concrete strut, which is the main load transfer element in deep beams. The objective of this research was to understand the structural behavior of continuous reinforced concrete deep beams. Numerical non-linear analysis, of six continuous (two-spans) reinforced concrete beam models, was carried out using a 3-D FE program; ABAQUS. All the analyzed beam models were loaded to failure under the effect of two concentrated loads, one being placed at mid-span of each span through a steel plate. Behavior of beam models is discussed and the ultimate strength was compared with those obtained either from a Strut-and-Tie model analysis or from suggested code equations. The non-linear analysis predicted well the behavior of beams up to the ultimate strength. The ultimate loads obtained from the numerical analysis overestimated the strength calculated by STM by 9- 34%. However, close values of strength were obtained from STM compared to the Egyptian Code recommendations for flexural strength.
