Nonlinear displacement response of reinforced concrete structure is investigated by a parametric study of SDOF system with appropriate hysteresis properties and ground motions used commonly in the design. The result shows that the maximum value of the nonlinear displacement response can be divided into two regions by a set of dimensionless parameters defined by strength, initial period and the type of ground motion. The maximum value of the nonlinear displacement response of the system in region I would be less than the smoothed displacement spectral value with 2 % damping. The nonlinear displacement responses for typical buildings are shown for historical ground motion records using this result.
