Barge Train Maximum Impact Forces Using Limit States for the Lashings Between Barges

Abstract

In 1993, Headquarters, U.S. Army Corps of Engineers issued the first formal Corps-wide analysis procedure providing guidance for analyzing the effects of barge impact loading on navigation structures. According to the ETL 1110-2-338 engineering procedure, the magnitude of the impact forces generated by a particular collision event is dependent on: the mass including hydrodynamic added mass of the barge train, the approach velocity, the approach angle, the barge train moment of inertia, damage sustained by the barge structure, and friction between the barge and the wall. There have been two significant concerns raised since the ETL 1110-2-338 procedure had been released. Mainly, several engineers who have used the ETL 1110-2-338 engineering procedure have questioned the accuracy of the computed results. In 2003, the U.S. Army Corps of Engineers issued a Technical Report that addresses the interpretation of eight of the 44 December 1998 full-scale, low-velocity controlled impact, barge train impact experiments conducted at the decommissioned Gallipolis Lock at Robert C. Byrd Lock and Dam. According to the ERDC/ITL TR-03-3, an easy to use empirical correlation is derived that reports the maximum impact force (normal to the wall) as a function of the linear momentum normal to the wall (immediately prior to impact), using the results from the impact forces measured during these full-scale impact experiments. This new empirical correlation will be used for impacts that do not involve damage during impact to either the corner barge of a barge train or to the wall. An alternate empirical correlation is given for the maximum impact force (normal to the wall) as a function of the kinetic energy normal to the wall (immediately prior to impact).
