Abstract

Abstract

In order to improve the mechanical properties of the negative bending moment zone of steel UHPC waffle bridge decks, a staggered joint was proposed against the background of Wenchang Bridge, and four groups of steel UHPC waffle bridge deck joint specimens were designed and manufactured for bending tests. The effects of different factors, such as steel fiber type and joint type, on the failure mode, bearing capacity, reinforcement strain, crack extension and other properties of the specimens were compared and analyzed. The mechanical properties of the steel UHPC wiffle bridge deck undered the normal service limit state and bearing capacity limit state were evaluated and analyzed. The results showed that the specimens showed typical ductile bending failure, and the cracks were concentrated below the loading point and in the joint area; both staggered joints and end hook fibers could effectively improve the bearing capacity and deformation capacity of specimens; there were two stages in the crack development curve of each specimen: crack holding and force holding. When the crack width was 3 mm, the load borne by butted joint specimen DD was 14.8% higher than that of DZ, while the staggered joint specimen CD was only 5.3% higher than that of CZ; in the serviceability limit state and bearing capacity limit state, UHPC waffle bridge deck had excellent bearing performance, and met the design requirements of "strong joints, weak members".
