The torsional behaviors of composite box girders with corrugated steel webs are more obvious than traditional concrete girders due to the lower torsional rigidity.
In this paper, the torsion and distortion of this kind of composite girder are studied.
The formulas for warping normal stress and shear stress were put forward according to the second theory of Umanskii, considering the accordion effect of corrugated steel webs.
Then, the influences of different dimensional parameters on the torsional and distortional stress are investigated.
Results show that the effect of parameters on stress is different and implicit in composite box girders with corrugated steel webs.
Under eccentric loads, the warping torsional and distortional stress in this kind of girder should not be neglected.
Compared with girders under corresponding symmetric loads, the total warping stress may be as big as flexural normal stress, and the total shear stress usually reaches 30 to 50 percentage of flexural shear stress.
So the warping stress and additional shear stress due to warping torsion and distortion are suggested to be calculated by the proposed equations in structural analysis, which are usually not taken into account in conventional concrete box girders.
