The spatial distributions of dynamic response of an artificial large-scaled floating island subjected to wind-induced waves and seaquakes are obtained by using both long-term and short-term descriptions of loadings and stochastic response analyses of the linearized dynamic model. The long-term descriptions of external loading are represented by the probabilistic density functions of load intensity. The short-term descriptions of external loading are represented by the spectral density functions of excitation in terms of each load intensity level. The short-term response distribution of the island is evaluated by a stationary random vibration analysis. Then the long-term response distribution of the island is evaluated by summing the contribution of short-term response distribution due to each load intensity level. Numerical examples are presented to discuss the short-term and long-term response distributions of the floating island against both wind-waves and seaquakes.
