It has been pointed out from tests, analyses and earthquake damages that column shear forces in beam-yielding reinforced concrete frames could be higher than calculated from an analysis neglecting inelastic axial elongation of beams, which is caused by the material properties of reinforced concrete including crack opening behavior. However, the effect of the beam elongation has been neglected in practical design analysis, even by the most sophisticated nonlinear analytical method. The purposes of this study are to investigate experimentally the behavior of beams under axial restraint, and to establish a simple analytical model in order to evaluate the axial elongation and the restraint force in beams.
