An elastic beam bending theory for analysis of prestressed concrete girders with corrugated steel web is derived by the application of the variational principle. The theory is a shear deformable beam theory which is based on three displacement elds and is similar to the classical Timoshenko beam theory. A two-node linear nite element with full and reduced integration of the theory is provided. It is then used to analyze simply supported and continuous I-and box-girders. Their predicted results are found in good agreement with those by the 3D nite element analysis. A simpli ed theory which is similar to the proposed theory by Kato et al. (2002) is also discussed and included in appendix.

A developed form of the PC box girders using corrugated steel web are flourishingly under construction. The form has been used for the continuous girders and the usage to be developed even for the cable stayed bridges. Since the corrugated web does not possess rigidity along the span axis, the influence due to shear deformation strongly appears. The authors have developed an elastic equation extending beam-bending theory considering shear deformation. The dual three-moment method and the CWB (Corrugated Web Beam) matrix displacements-method are formularized. The obtained knowledge is so important that the practical bridge engineers should take it into their consideration.

Utilization of corrugated steel plate as web in PC girder markedly separates functionality of flanges and web in resisting external force. The web responses mainly to resist for shearing force. However, by such separation, transferring of shearing force at the point of loading into the web seems to be retarded. The so-called shear lag phenomenon in the web is thought to occur. In this study, an extended beam theory is developed by considering that the web is shear deformable and satisfies Timoshenko beam theory. The governing equations and boundary conditions are derived by the variational principle. The calculated results based on the extended theory are then verified with those by the finite element analysis on a number of girder where a good agreement is found and the shear lag phenomenon in corrugated web is revealed.
