Abstract An economical approach was developed to examine the effect of radiation damping on earthquake response of pilesupported offshore platforms. Parameteric studies were conducted to evaluate the effects of radiation damping on response. Various features of this effect were found for pile head stiffnesses, and responses of platforms subjected to harmonic and earthquake excitations.
