In this paper, bending analysis of simply supported composite beam is carried out by using refined beam theories. The theory accounts for the parabolic variation of shear strain through the depth of beam, hence avoid need of shear correction factor. The governing differential equations and boundary conditions are obtained by using the principle of virtual work. A simply supported composite beam subjected to central concentrated load is considered for detail numerical study. The results of displacements and stresses are obtained and found agree well with those obtain by other higher order and lower order theories.
