Abstract
Barges generally have an even distribution of load weight on the deck. The tendency of barges to experience hull fractures is at 0.2 ~ 0.7 L during material loading mode.The pupose of the research is to determine the ultimate strength of barge construction during loading mode. The method used is a numerical simulation. The research results show that the maximum stress value under hogging conditions for loadcase 1 and loadcase 2 with intact plate thickness is 221.204 Mpa and 223.207 MPa, the maximum stress value in hogging conditions for loadcase 1 and loadcase 2 with 20% reduction in plate thickness is 188.973 MPa and 196.303 MPa, and the maximum stress value in hogging conditions for loadcase 1 and loadcase 2 with a plate thickness reduction of 25% is 170.054 MPa and 164.861 MPa. The largest ultimate moment value was obtained in loadcase 2 hogging conditions with intact plate thickness, namely 1.92 x 1011 Nmm. The thinner the construction plate, the lower its ultimate strength will be. The addition of sideboards to the barge deck can also affect the ultimate strength value he construction safety factor is rated 1.064 ~ 1.425.
