In this paper, the authers have dealed with the energy response of steel structures subjected to a severe earthquake and have proposed a consept of instantaneous damage energy w_d. It is shown that the w_d value is advantageous in evaluating the nonstationary energy input of intense earthquake, and has a good correlation with parameters such as the maximum velocity and the maximum ductility.
