dc.descriptionAbstract: In 1993, Headquarters, U.S. Army Corps of Engineers issued Engineer Technical Letter (ETL) 1110-2-338, the first formal Corps-wide analysis procedure providing guidance for analyzing the effects of barge impact loading on navigation structures. The ETL 1110-2-338 engineering procedure calculates the magnitude of the impact forces generated by a particular collision event 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. This ETL 1110-2-338 Corps guidance was rescinded in 2001 due to concerns regarding the accuracy of computed results. Later research hypothesized that the limit value of the force normal to the wall is based on the yield of the lashing. This work presents a parametric analysis of the limit states of the lashing and an analysis of the tendencies. The models used to perform the parametric analysis are the corner (glancing blow) and longitudinal (head-on) failure mechanisms and their empirical correlations. The analyses used the Limit_LASHING computer program to estimate the maximum force normal to the wall based on the limit states of the lashing between barges.-
