| Abstract | ||
| Twelve SCC I-Beams were designed to investigate the shear behavior under two concentrated loads. All beams have the same longitudinal steel ratio of (0.0145) and gross section area of (29000 mm2). The tested beams were divided into two groups with and without stirrups. The first group consist of three beams without stirrup having different values of compressive strength (fc`) but same value of clear span to effective depth ratio (ln/d), while the second group consist of nine beams with stirrups. It shall divided into three series according to the compressive strength (fc`) each series continued three beams at different value of clear span to effective depth ratio(ln/d).it was found that The ultimate shear strength predicted from A CI 318-08 is lesser than the experimental values, the ultimate shear strength of SCC I-beams increased about 46.728%,46.55%and 41.462% when the clear span to the effective depth (ln/d) decreased from (5.84 to 5.05) at compressive strength (fc) 29.36, 41.42 and 49.2 MPa respectively ,the ultimate shear strength for SCC I- beams with stirrups increase about 22.536%.15.27%and 10.828% when the compressive strength(fc) increased from (29.36 to 49.2 MPa) at clear span to effective ratio (ln/d) 5.84, 5.5 and 5.05 respectively, ,the ultimate shear strength of SCC Ibeams with stirrups increased about 42.66%, 38.09% and 39.77% as compared with ultimate shear strength without stirrups at compressive strength 29.36,41.42 and 49.2 MPa respectively. | ||
