AB  - The shear behavior of reinforced concrete deep beams is one of the most influential factors on the
total behavior of the structure. The arrangement of stirrups in concrete members, especially in beams has a
considerable effect on ductility and hysteresis behavior of the structure. The shear behavior plays a great role
in gravity loads of the structure and its failure mechanism. Due to their different behavior in compare to flexural
members, studying the cracking pattern in concrete deep beams seems necessary. In this study the cracking
pattern of concrete deep beams with web openings is considered. To do this, finite element models of six
concrete deep beams with web openings and without shear reinforcement were built by ANSYS Software and
verified using experimental results. The modeled beams had the same properties, except for the size and place
of the opening. The analysis results showed that both shear capacity and stiffness reduced by the increase in
the opening area. Collapse of the concrete beam was due to expansion of cracks on corners of the opening,
parallel to compression member of truss.
