The response of doubly reinforced concrete beams to variable repeated and reversed loading is predicted on the basis of technical beam theory and stress-strain relationsof steel and concrete under cyclic loading. A series of tests was performed to verify the theory. It is concluded that the response to repeated loading may be considered elastic-plastic for engineering purposes, but the behavior under ternating plastic city is highly nonlinear which can be predicted only by considering the Bauschinger effect in the steel.
