In order to study the behavior of inelastic deformation and hysteresis characteristics of prestressed concrete flexural beams, 66 prestressed concrete beams of rectangular sections were tested under reversed loading. The experimental variables in the test series included : a shear span ratio ; a tensile reinforcement index ; a ratio of tensile inforcement index for prestressing steels and for reinforcing bars ; the amount and spacing of confining reinforcement ; and the location of prestressing steels. On the basis of the test results, the conventional restoring force characteristics model, of prestressed concrete flexural beams, was proposed. With respect to the deformation at flexural yield and the hysteretic damping ratio, agreement between the calculated values predicted by the model and the measured values were considerably good. Furthermore using this model, an earthquake response analysis for reinforced concrete column was made, and the analytical results were compared with the pseudo-dynamic test results. The analvtical results agreed well with the test results.
