| Abstract: | Based on a shear experiment of 10 SRHSHPC(steel reinforced high-strength and high-performance concrete) simply supported beam specimens,this paper reveals the main factors which affect the beam's shear behaviors and obtains the relationship between the shear bearing capacity and the shear span ratio,concrete strength,steel ratio,stirrup ratio,flange width ratio(the ratio of steel flange width and beam width) and loading modes.According to the existing shear calculation methods of SRC beams,and adopting a tr... |
