A method of calculating the creep deflections and stresses of a beam-column is shown. The differential equation of equilibrium in terms of creep strain is solved by the method of integrating factors with Green’s function. For restrained and built-in ends, the end moments are found from the end conditions. An illustrative example is given for a beam-column of an ideal H-section with built-in ends and subjected to uniform lateral load. The deflection-time curve and flange stresses at different instants are shown.
