EVALUATION OF THE SHEAR CAPACITY FOR STEEL REINFORCED CONCRETE SHORT BEAMS UNDER FIXED BOTH ENDS

Abstract

 The experimental equations under the simply supported condition has been used as the shear capacity of steel reinforced concrete (SRC) beams in Standard Specifications for Hybrid Structures. On the other hands, the support condition of members of the rigid frame viaduct is different from the simply supported because both ends are fixed. The study has evaluated the shear mechanism and shear capacity of SRC short beams under fixed both ends based on results of experiment and finite element analysis. The results indicated that the shear capacity was affected by support condition and increased with the decrease of the flange width of steel-frame. In addition, the effect of stirrup on the shear capacity was limited. Finally, the paper proposed calculation equation of shear capacity for SRC short beams under fixed both ends.
