Considering the behaviors of unbonded prestressed concrete beams and steel reinforced concrete columns, a kind of nonconforming beam-column element was constructed and the analysis precision was improved. Loading and reloading paths were introduced into the constitutive relationship of concrete. It is helpful to the analysis program to trace the full-range mechanical behavior of structures including the descending part and the hysterisis characteristic under cyclic loading.
