C ONCLUSION

ased on the obtained results the following conclusions could be drawn:  In all cross-sections, the obtained beta index for the combination of bending-shear is between shear and bending state such that the beta index is higher than the bending state and lower than the torsion state.  The beta index for a combination of bending-torsion is between torsion and bending state such that the beta index is higher than the bending state and lower than the torsion state. This surface is close to the bending state which means bending equations have a significant effect on the combination surface. B
