Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Engineering - Department of Civil Engineering Summary: An experimental program was carried out to investigate shear behavior of recycled reinforced concrete beams with openings. Nine specimens were tested with different parameters, such as recycled concrete aggregates ratio, openings in beams, opening height, opening position and reinforcement around the openings. Specimens consisted of two beams with NCA, another two beams with 100% RCA ratio and five beams with 50% RCA ratio. The results showed that using recycled concrete aggregates in beams decreases shear strength and increases the deflection of beams. Openings in beams with NCA and RCA decreases shear strength of beams. Increasing opening height from 10cm to 15 cm slightly decreases shear strength. Opening position was significantly affected on shear strength when approaching the maximum shear zone.Increase steel reinforcement around the openings improve the shear strength.
