In order to control maximum response displacement of a structure under earthquake ground motions, the structure is required to have proper strength and cyclic deterioration capacity. In the previous paper, EIV which was defined as energy input velocity under stationary vibration was formulated. EIV was represented as a function of strength(Py) and maximum response displacement (δ max). In this paper, a procedure to determine the strength(Py) and the cyclic deterioration capacity which were required to control maximum response displacement was presented based on the concept of EIV. It was confirmed that EIV was almost equal to actual energy input velocity (ΔE /Te)max of inelastic response. Strength(Py) required to control maximum displacement was obtained by solving the relationship, EIV=(ΔE /Te)max. The strength(Py) was represented as a function of design maximum displacement (δ_D), total input energy(E_D) and actual energy input velocity (ΔE /Te)max. The procedure to determine the strength(Py) was validated from inelastic response analysis. In order to control maximum displacement, it is necessary to secure not only proper strength but also enough cyclic deterioration capacity. The capacity was defined based on EIV and its characteristics were discussed.
