Description: Technical Report
Abstract: In 2003, the U.S. Army Corps of Engineers issued ERDC/ITL TR-03-3, which interpreted eight of the 44 full-scale, low-velocity, controlled-impact barge train experiments conducted at the decommissioned Gallipolis Lock at Robert C. Byrd Lock and Dam. An easy-to-use “empirical correlation” was derived, reporting the maximum impact force (normal to the wall) as a function of the linear momentum normal to the wall (immediately before impact). This empirical correlation was cited in ETL 1110-2-563 (April 2004) for impacts with stiff-to-rigid walls that do not involve damage to either the corner barge or the wall; a limiting impact force of 800 kips (capping the empirical correlation) was cited. In this technical report, we provide a basis for revising the “capping force” cited in ETL 1110-2-563, based on the computation of the “crushing” force imparted during a glancing blow of the impact corner at the bow with a lock approach wall. A second limiting force due to the limit state of lashing forces during a glancing blow impact is addressed in the USACE technical report ERDC/ITL TR-05-1. The lower of the two limiting forces - due to the crushing of the barge impact corner or to the failure of the lashings - “caps” the empirical correlation.
