Abstract

The influence of seven factors, including shear span ratio, reinforcement grade, reinforcement diameter, reinforcement spacing, section width, section height, and concrete strength, on the shear bearing capacity of Ultra high performance concrete with coarse aggregate (UHPC-CA) beams containing high-strength steel bars was analyzed using orthogonal experimental method. The results show that the influence of various factors on the shear bearing capacity of high-strength steel reinforced UHPC-CA beams, from large to small, is in the order of section width>concrete strength>shear span ratio>section height>hoop diameter>hoop spacing>hoop grade. The shear capacity of high-strength reinforced UHPC-CA beams decreases with the increase of shear span ratio and hoop spacing, and increases with the increase of hoop grade, hoop diameter, section width, section height, and strength of ultra-high performance concrete containing coarse aggregates.
