Abstract

An equivalent static method is employed in calculating the impact response of vessel-bridge collisions, in which the dynamic characteristics of vessel-bridge collisions are ignored. An impact response spectrum for vessel-bridge design is proposed according to the principle of the earthquake response spectrum. The impact force time-histories are obtained through a numerical simulation method using finite element software. The relationship between the displacement amplification factor of the single-degree-of-freedom, period, and damping ratio under the excitation of impact force-time histories is obtained. The regularity of the displacement amplification is summarized. The characteristics of the vessel-bridge collision are given. The three-stage expression and specific application steps of the impact response spectrum for the design of vessel-bridge collision are provided.
