Abstract

This paper presents two bridge design methods that model the dynamic interaction between the individual barges in a multiple barge flotilla and the bridge pier during a collision. The methods use either a single inertia! or multiple mertial mode response coupled with a pseudo-static response The modal mertial and pseudo-static response to the impact is determined from the impact spectrums and peak impact load equation developed by the authors The design procedures are called the Pseudo-Dynamic Analysis Procedure (single mertial mode method) and the Impact Spectrum Analysis Procedure (multiple inertial mode method). 1 Introduction The current method of analysis of bridge piers subje
