Abstract

Abstract

The equivalent bending rigidity of steel-concrete composite beam was derived, it was found that the rigidity was composed of two parts: one is the bending rigidities of the slab and the steel section about their own centroid axes, the other was the truss stiffness whose upper chord was the slab and lower chord was the steel section and the studs were the web members, and a simple calculated formula was proposed. The deflection due to the shear strain of the steel web and the interfacial shear-slip stiffness of the stud are also presented.
