Content
NB! This is an elective course and may be cancelled if fewer than 10 students are enrolled by August 20th for the autumn semester.
Analysis and design for ultimate actions/limit states
- Overview of theories of plate bending, local buckling, torsional buckling, lateral torsional buckling and torsional flexural buckling.
- Design of plated structures, thin-walled sections, stiffened plates, plate girders, bridge cross sections and bracing systems.
- Nonlinear modelling and analysis of structures for quasi-static and dynamic loadings. Plastic push over analysis, 2nd order analysis, P- Δ analysis, large displacement analysis and time-domain analysis.
- Elastic analysis of complex joints and design of joint components according to Eurocode.
Analysis and design for accidental actions
- Overview of design and analysis methods for accidental loads to civil and marine structures.
- Blast and explosion design and analysis. Design philosophy and method with reference to various design standards are presented.
- Accidental actions from ship collisions with bridges, offshore platforms, wind turbines, and other ships. Structural design against accidental loads according to codes and guidelines including NORSOK, DNV RP, and Eurocode.
- Design and analysis of dropped object impact.
- Case examples of collision and impact analysis using LS-DYNA. (Computer-aided case study assignment)
Analysis and design for fatigue
- Basic fatigue theories and application of civil and offshore steel structures
- Fatigue load models, fatigue strength curve of structural details and design methods according to Eurocode and DNV GL.
- General concepts in health monitoring and integrity assement of structures including fields of applications (i.e. Introduction to structural health monitoring methods and damage detection)
