Abstract
The number of corrugated steel web bridge has steadily increased in terms of its structural rationality and labor-saving. On the other hand, the shearing behavior of corrugated steel web which is fixed all edge by concrete cannot be said that it has been already clarified. Thus, experimental research using full scale model and half size model of actual box girder was carried out to solve it. That research showed that the contribution of corrugated steel for shear increases accompanying with progress of cracking in concrete member and after reaching to yield shear stress, that contribution decreases gradually. And shear buckling behavior of the corrugated steel which is restrained by concrete progresses slowly, not suddenly.
