Concrete-encased composite girder with corrugated steel web is proposed to improve the
mechanical performance of continuous girder under hogging moment, avoiding the buckling of the
corrugated web and compressive flange caused by large combined shear force and bending moment.
The structural behavior under combined shear force and bending moment was investigated
experimentally and analytically, the load-carrying capacity and failure mode of composite girders
with different length of concrete encasement were investigated. Analytical results show that the
failure modes of composite girders depend on the length of concrete encasement, and the ratio of
shear to bending affects the shear stiffness after concrete cracking and ductility at ultimate load
state. Based on experimental results, the analytical evolution of shear strength and bending strength
were investigated, also interaction equation with respect to shear and bending strength was
proposed to evaluate loading capacity of such composite girders.
