Abstract

In this paper, an experimental study on the real stress state of the hinge joint is carried out for the prefabricated hollow girder bridge. The tests were divided into three working conditions: 1) center cloth loading, 2) symmetrical cloth loading on both sides and 3) cloth loading on one side. From the test results, the measured transverse distribution values of the boards under three working conditions are all lower than that of the value calculated by Hinged Plate theory, and the distribution curve is more flat. In addition, under the three conditions, there is positive strain in the transverse direction of the concrete joints, and the strain distribution is uneven with tensile and compressive strain coexisting along the cross-sectional height of the joint. Judging from the bridge design theory and test results, the concrete joints of hollow slabs has the function of internal force transmission between the slabs, and the concrete joints are under the action of shear force and bending moment.
