摘 要：
The torsional experiment of the variable cross-section box-girder bridge with corrugated steel webs was carried out to research its torsional properties;and the model of the boxgirder bridge was established and analyzed by the finite element software.The practical analytical formula of the torsional stiffness of variable cross-section box-girder bridge with the corrugated steel webs was proposed on the basis of the mechanical features of the composite girder bridge.The validity of analytical formulas of the torsional stiffness was proved by the study on the real-bridge test and the finite element analysis;and the related study of the the practical analytical formula of the torsional stiffness of variable cross-section box-girder bridge with the corrugated steel webs will provide data reference for the design of the variable cross-section composite box-girder bridge.
