The sandwich deep beam are used to reduce the self-weight, deflection and shear by inclusion of thermocol and weld mesh. The outcome of recent research undertaken on concrete deep beams with and without reinforcement In this project study with experimental studies which have been conducted to understand the various modes of failure that could occur due to possible combination of shear and bending moment acting at a given section. The main obstacle to the shear problem is the large number of parameters involved Reinforced concrete deep beams are used as load distributing structural elements such as transfer girders, pile caps, foundation walls, and offshore structures. The shear strength evaluation of reinforced concrete beams has been the subject of several studies devoted to determine the influence of the main parameters. Due to the small value of span-depth ratio, the strength of deep beams usually controlled by shear strength rather than flexural strength, if normal amounts of longitudinal reinforcement are used. Shear force presents in beams at sections where there are a change in bending moment along the span, it is equal to the rate of change of bending moment. Apart from highlighting the experimental set-up, typical crack patterns, failure modes, and load-deflection behaviour are also reported.
