The purpose of this study is to establish a simple method for estimating differential displacement based on the vibration characteristics of a single structure in consideration of structural nonlinearity during earthquake. A simplified method for estimating differential displacement considering nonlinearity is proposed. The validity of the proposed method was confirmed based on the numerical simulations .
