Abstract: Evaluation of strain energy from the tests of reinforced concrete beams subjected to a moving load is presented in this paper. The effect of a moving load on the deformations was investigated on 3 reinforced and 4 partially prestressed concrete beams. The moving load was simulated by activating and deactivating- a set of hydraulic jacks placed along the beam resulting in a force similar to the moving load. The arrangement of measurements enabled the separation of the effect of bending moments from that of shear forces. The run of a loading force along the beam enabled the evaluation of the elastic and inelastic part of the strain energy. The results show that the effect of the shear force, on the irreversible part of the deflections, is higher than that due to the bending moment.
