We propose tuned mass dampers with initial displacement that are possible to control impulsive seismic responses effectively. In our previous study, we focused on the considerably high modal damping ratio of the second mode compared to the first mode and proposed the design formulas for high control performance under impulse loading. The proposed design formulas are based on the principle that by giving the specific TMD initial displacement under the specific structural initial condition the structural response of the first mode can be eliminated. In this paper, we introduce a formula for initial conditions to release initial displacement by the theoretical solution and study about TMD initial displacement and structural conditions by using the complex plane. Next, we propose a design method that can change initial structural conditions.
