SUSPENSION BRIDGE STIFFENING GIRDER AND CONSTRUCTION METHOD FOR SUSPENSION BRIDGE STIFFENING GIRDER

摘要

Disclosed is a suspension bridge stiffening girder equipped with a plurality of main girders that are disposed, with a space therebetween, in an orthogonal direction to the axis direction of the suspension bridge in a manner following the aforementioned bridge axis direction, a plurality of crossbeams that are disposed between the aforementioned adjacent main girders in a manner following an orthogonal direction to the aforementioned bridge axis direction, and a highly-durable concrete deck slab that is disposed on the top of the aforementioned main girders.
