The purpose of the subject is to establish methodology for finite element modelling and analysis of structures, with respect to design according to limit state principles, with due account of relevant loads due to waves, wind, earthquakes, ice and accidental loads such as actions from ship collisions, grounding, falling objects, explosions, and fires. Analysis of damaged structures is an important aspect of modern design practice and is included. Topics: Introduction to nonlinear static and dynamic analysis with the finite element method of structures with geometric nonlinear and elasto-plastic behaviour as well as analysis based on simplified plastic methods. Modelling and analysis of beams, frames, stiffened panels and shells as structural components as well as structural systems in the form of ships, platforms and offshore wind turbines. Assessment of error sources in the structural analysis, dependent upon the mathematical modelling of loads and structure as well as discretization and round-off errors in the finite element model.
