Maximum displacement response of 1 DOF system subjected to 1 cycle sine wave is calculated in order to estimate the maximum displacement response of structures in any earthquake. As results, the maximum velocity responses of linear system based on this proposed method have the constant maximum velocity. The period of sin wave that makes the structure most deformed is 0.85 times of the natural period of that structure. In order to prevent structures from large deformation, there is a threshold base shear coefficient in each restoring force characteristic case. The estimated maximum displacement response displacement is less than 1.2 times of the displacement based on this proposed method.
