This paper describes estimation of load-deformation characteristics concerning precast prestressed concrete flexural members, in which a combination of unbonded post-tensioned (PT) reinforcements and bonded deformed bar reinforcements are used. The unbonded PT reinforcements are designed not to yield during seismic excitations, so as not to decrease a self-centering force. On the other hand, the bonded deformed bar reinforcements are intentionally designed to yield for energy dissipation. In order to estimate the load-deformation characteristics and material strains of the members simultaneously, a newly developed macro model that reflects behavior of the plastic hinge zone of the members is applied and compared with test results. By the comparison, the macro model is verified to have enough accuracy for practical use.
