The way to substitute corrugated steel webs for concrete webs of a box girder bridge will result in no restraint among the upper deck slab, lower deck slab and webs of the bridge, alleviate influences due to concrete creep, drying shrinkage and temperature differences, and consequently achieve the purpose of an active control design. On the basis of the massive data of the observed bridges, this paper describes in details the design method for the box girder bridge composited with corrugated steel webs, inc...
