Abstract

This study deals with shear behavior between normal and self-compacted concrete beams. The experimental work includes the design and testing of twelve reinforced concrete rectangular beams to study the effect of using self-compacted concrete (SCC) and normal concrete (NC) on the shear behavior under two concentrated load. All beams have the same longitudinal and vertical steel ratio and cross-sectional area of (17000) mm2. The tested beams were divided into two groups; SCC and NC beams. Each group was divided into three series according to clear span to effective depth ratio (ln/d), each. series consists of two compressive strength of concrete (f'c). It was found that the beams which made from SCC was stiffer as compared. with the beam made from NCC with the same clear span. to effective depth ratio, longitudinal steel ratio, vertical steel ratio, and relative compressive. strength. This equation is conservative. as compared with. for NC beams. tested while the ACI 318 equation is more conservative as compared with the SCC beams tested. It was found that the ultimate shear strength of SCCb increased about 16.66%, 20.33%,20.88% when the compressive strength (f'c) increased from (29.39) to (42.1)MPa while the shear strength of NC increased about 9.3%,12.9%,14.9% when the compressive strength (f'c) increased from (27.8) to (39.1)MPa at clear span to. effective depth ratio (ln/d) (7.534),(6.164),(5.584) respectively. It was found that the shear strength of SCC increased about 12.5%, 18.75% ...
