ABSTRACT:

Curved continuous composite girder bridge accompanies with bending-torsional coupling effect when subjected to vertical load, and there is also a concern on the buckling of steel bottom flange in the negative moment region. A structural type of curved continuous girder bridge with a double composite section in the negative moment region is proposed, consisting of a steel tub with a concrete top slab and a concrete bottom slab, which are connected to each other by shear connectors to carry load together. In order to investigate the mechanical properties of this structure, a parametric analysis was carried out on the effect of concrete bottom slab dimension and connector arrangement. Under the action of eccentric load, the longitudinal distortion stress and the distortion angle of the curved continuous double composite girder bridge was compared. Results show that the double composite action can reduce the longitudinal distortion stress and the distortion angle of the section, and only vertical studs are needed.
