Longitudinal stresses are created since the vessel generally grounds aft first and this creates longitudinal bending stress on the ship.Resistance to the stresses will be by all longitudinally continuous material,particularly those items furthest from the neutral axis.E.g.,upper deck,bottom shell,and tank top together with associated longitudinals,girders,etc.(as for resistance to Some results are removed in response to a notice of local law requirement.For more information,please see here.12345NextStress Analysis of Cylindrical Steel Storage Liquid Tanks Proceedings of the 3rd World Congress on Civil,Structural,and Environmental Engineering (CSEE18) Budapest,Hungary April 8 - 10,2018 Paper No.ICSENM 128 DOI 10.11159/icsenm18.128 ICSENM 128-1 Stress Analysis of Cylindrical Steel Storage Liquid Tanks During theSTRUCTURAL ANALYSIS AND DESIGN OF A REINFORCEDA cylindrical tank is an axisymmetric structure.If the load is also axisymmetric,then the same stresses will be generated along any meridian section of the tank.
