Abstract
Transfer beams in coastal projects and foundations, bunker walls, and load-bearing walls in buildings are all popular applications for reinforced concrete deep beams. Openings in such beams are required to enable doors and windows, as well as equipment such as ventilation ducts and air conditioning systems. The deep beams with openings would reduce its shear capacity, posing a major safety issue. Only a few investigations onbehavioral aspects and capacity of deep RC beams with openings have been published. Because such openings are unavoidable, adequate reinforcing measures must be adopted to compensate for the loss of strength. The purpose of this experiment is to investigate deep beams with various types of openings. Casting and testing of three deep beams with openings under a two-point load. The sample has a 150mm x 500mm cross section and an overall length of 1.2 m. There are two openings in each beam and they are symmetrically placed around the mid span of the beam, one in each shear span.The percentage decrease in the ultimate load of thelong square-opening girder is 4,032% compared to the long round-opening girder. Deep beams with square and circular openings failed due to shear and exhibited shear cracks.
