Abstract: A Deep beam is defined as a structural member having aspect ratio (L/D) less than 2.0 for simply supported beam, less than 5.0 for continuous beam and dominated by shear deformation. In the experimental investigation six deep beams are casted, out of which two are conventional beams, two are chlorinated and remaining two are added by bolts and nuts. The main objective of this paper is to investigate the behavior of RC deep beams under different exposure conditions. Parameters under consideration are shear behavior of RC deep beams, modes of failure, load deflection response, factors affecting strength, crack pattern. Emphasis is also given to study the behavior of deep beams in resisting deflection and cracking along with serviceability conditions like fatigue, vibration and durability. As the serviceability performance checks are mandatory for structural members exposed to environmental conditions which ultimately effects strength, performance of RC deep beams are quantified and tested to check the width of diagonal spacing cracks that form under the application of service loads.
