ABSTRACT

The Deep beam is defined that members with clear spans to depth ratio equal or less than four times the overall member depth. Reinforced concrete (RC) deep beams are used as load distributing structural elements such as transfer girders, pile caps, foundation walls, and offshore structures. To overcome this load transfer difficulties deep beams are applied in construction. The provision of the web openings in the concrete beams are provided for the pipelines and cable laying in the high rise commercial buildings. The present study is to determine the shear carrying capacity of deep beams with multiple circular web openings. The deep beams were casted of size 1100x150x450 mm. The reinforcements were provided as 0.49% on bottom and 0.83% on top side. The total of six beams was casted three for each reinforcement ratios. The significant results were arrived are provided in this research article.
