Abstract: The deformation calculation formulas under long-term and different loading of prestressed steel reinforced concrete beams are built up by using age adjusted effective modulus method according to internal force equilibrium and strain harmony of section. Based on that, numerical methods are applied to calculate and analyze stress redistribution of steel and concrete, deformation of beam in different time slice, as well as the curves about how concrete strength, axial force, moment, volumetric percentage of steel and volumetric percentage of tendon affects mid-span deformation of long-term loading beam.
