Secondary Loading and Stresses

Abstract

This chapter gives a full analysis of the secondary loadings and stresses induced in the strength members of cargo ships and conventional oil tankers. Strength members sustaining secondary loadings and stresses of transversely and longitudinally stiffened bottom and deck ship structure assemblies are specified. The secondary stresses induced by the bending of double and single bottom structures are presented for hogging and sagging conditions. The loadings and stresses induced in deck and bottom girders, longitudinals and plating are highlighted. Secondary loading and stresses induced in bottom girders, longitudinals and plating as well as tank top longitudinals and plating are defined. Secondary loading and stresses in bottom structure assemblies of oil tankers are identified.
