Behavior of Curved Box Beam Bridges. The Design of Curved Viaducts.

摘要

The behavior of single span curved box beam bridges,has been predicted by the stiffness method. The bridges consist of box sections,which are composed of steel web and flange plates,in componte action with a concrete deck. The box sections are single units with individual webs. Variations in girder spacing,number of lanes,number of girders,span length and radius were considered in the parametric study,resulting in a total of ninety bridge configurations. These bridges were then loaded with the AASHO Truck,and the resulting deformations and forces evaluated. (Author)
