Abstract

Abstract:

A torsional theoretical model （PCA-STM） applicable to composite box girders with corrugated steel webs （CSW） is proposed based on the combined action softened truss model （CA-STM）， and an optimized algorithm is given. This model takes into account the prestressing effect and introduces a deformation coordination relationship between the CSW and the concrete slabs based on the yield state of the CSW. The accuracy of the theoretical model is verified by experiments and the results show that PCA-STM can well predict the full torsional behavior of the composite box girders with CSW， including the torque-twist curve， shear strain curves of concrete and CSW.

Key words: bridge and tuunel engineering, combined action softened truss model, corrugated steel webs, optimized algorithm, pure torsion
