Seismic performance of steel structure is based on the energy absorption capacity of structural members. Energy absorption capacity of steel member is determined by cumulative plastic strain. Therefore, it is important to evaluate how the steel member and material are related respectively on the plastic deformation capacity. In this study, the numerical analysis on beams and beam-columns was carried out. The analytical parameters were the lengths of members, material properties, axial force ratios, and cyclic loading types. The stress-strain relationship on the node of member was evaluated by plastic deformation capacity, accompanied with hysteretic behavior of member. The results showed that the reasonable relation between material and member on plastic deformation capacity under hysteretic behavior could be explained by the energy absorption capacity.
