Abstract

The precise analysis of reinforced concrete beams is a sophisticated problem, with several opening the problem becomes more complicated. With this in mind, it is essential to provide an intensive experimental information for the analysis of the reinforced slender beams designed with openings. The present study aims to investigate the impact of reinforcement of concrete beam with openings on its flexural behavior in terms of load and deflection. To achieve this goal, set of experimental tests have been conducted on three casted concrete cubes with and without different w/c and plastizer ratios. One layer of steel mesh was used for reinforcement. A concrete mix was designed with a compression strength of 43.6 MPa. The key variables in the present work were shape, location, number and dimension of the openings. The reinforced concrete beams samples were shaped with 400mm height, 1000mm length and 100mm width. The objective functions were mode of failure, the failure load, and the shear strength. The deflection tests revealed that fabrication of a one-layer reinforced concrete with different shapes and locations of the openings provides a better load capacity of the composite and presents a good matrix candidate for the structural applications with openings.
