【Abstract】 In this paper,the relation between instantaneous energy of earthquake actions and maximum displacement of the structure for both the elastic and bilinear SDF systems of different period was studied.The study also took the influence that the system parameter acted on the relation into account.And the equivalent input velocity and its changing rule were discussed in the article.The way to estimate the maximum displacement from the instantaneous energy was also discussed.更多还原
