In this paper, inelastic seismic behaviors of "stiffness and strength" asymmetric frame structures are investigated. The effectiveness and importance of "high ductility" design for asymmetric structures are emphasized to reduce dispersion of structural response caused by eccentricity. Comparative studies by using various kinds of asymmetric frame models which make different values of "maximum ductility factor response" are executed through numerical simulations. Analytical procedures are operated by extraction of each hysteretic model according to each value of maximum ductility factor response which is targeted on the frame model. Various cases of maximum ductility factor response are evaluated. As a result, it is assured that high performance of energy absorption is operated by introducing high ductility efficiency to asymmetric frame model.
