Abstract
Modelling and Analysis was carried out using Finite Element to study the behaviour of composite beams according to Euro code 4 with respect to bending, shear and deflection under varying loads, and the ultimate loadings and section capacities corresponding to failure modes was evaluated. In bending the section capacity was found to increase with an increase in both concrete and steel strength however increase in flexural resistance with increase in compressive strength is very small that is 3.2% 3.1% and 3.0% when the concrete strength was increase from 25 N/mm2 to 30, 35 and 40 N/mm2 respectively, compare to the way it increase with increase in the steel strength by 27% and 21% when the strength was increase from 275 to 355 and 460N/mm2 respectively, but the ultimate flexural load capacity of the beams decreases with increase in the beam span for both the three steel strength. However, shear capacity of the sections remain unchanged at constant steel strength and varying length, but increases with increase in ultimate yield strength of the steel sections by 29%, and 67% when the ultimate yield strength was increase from 275 N/mm2 to 355 N/mm2 and 460 N/mm2 respectively, while allowable deflection increases with an increase in the beams span and the ultimate loadings with respect to deflection also decrease with increase in the beams span.
