An evaluation method for the earthquake resistant performance of reinforced concrete columns and beams are developed for the performance based design. This paper describes the evaluation method of shear force- deformation relationships of reinforced concrete members. The main features are, 1) shear stress - strain relationships of R/C members are modeled as inelastic after cracking and flexural yielding, 2) shear stiffness after cracking are calculated based on the truss theory and 3) R/C member is separated into five regions to consider inelasticity of reinforcements and concrete. The shear force - deformation relationships of R/C columns and beams calculated by the proposed method shows good accordance with their experimental ones.
