A parametric analysis on load-deformation relationship of unbonded prestressed concrete beams, which had varied sections and were subjected to antisymmetric moment distributions, was carried out. The method of the analysis was the same one described in part 1 of this paper. The main parameters were prestressing and reinforcing steel ratio, shear-span ratio, and the compressive strength of concrete. As a results, it was confirmed that q_0 (= P_0/bDσ_B) is an essential value to characterize the structural behavior of unbonded prestressed concrete beams, and a method for predicting the load-deformation relationship of unbonded prestressed concrete beams subjected to antisymmetric moment distributions is presented.
