Development and Verification of Simplified Collision Model for Pile Protective Structures

摘要

In this study,a simplified collision model of pile protective structures against a navigation vessel was proposed and verified.The model of pile protective structure were composed by two plastic hinges at below of cap slab and the inside of ground.A nonlinear equation of motions was developed in consideration of the kinematic energy,potential energy and deformation energy in collision event.The developed simplified model were verified by the precise finite element collision analysis of the vessel and the protective structure.
