Structural peak relative displacement when  = 0.001, K = 100 kN/m,  m, and  m (DS1, DS2, DS3, and DS4 are defined by the structural peak relative displacement in Table 2). (a)  = 0.001 m⁻¹ and C = 0 kN·s/m. (b)  = 0.002 m⁻¹ and C = 0 kN·s/m. (c)  = 0.003 m⁻¹ and C = 0 kN·s/m. (d)  = 0.003 m⁻¹ and C = 10 kN·s/m.
