Abstract

The stiffness of PC box girder bridge with steel web reduces as compared with the stiffness of normal PC box girder bridge with concrete web. Therefore, beam section must be reinforced by cross beams in order to maintain sectional form. This paper shows a calculation method for sectional deformation of box girder with steel web. This method is based on foldet plate theory. An definite example is shown due to examine a behaviour of box girder with corrugated steel web.<br>Finally the symplified calculation method for corrugated steel web is proposed.
