This paper defines the conditions required for a composite beam to exhibit ductile sagging behavior. The variations in the elastic and inelastic response of a composite beam in sagging bending are studied. The effects of material properties, geometry, residual stresses and interface slip are all examined. From a wide range of cross-sections, the form of a standard moment-curvature curve is determined. Simple analytical expressions are derived which give an approximate prediction of the form of the complete curve throughout the elastic and inelastic range.
