Semester tution start
Language of instruction
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.
- Introduction to earthquake design.
- 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 objects 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 intefrity assement of structures including fields of applications (i.e. Introduction to structural health monitoring methods and damage detection)
Upon completion of the course, the students shall have a fundamental knowledge of the advanced non-linear analysis and design principles of steel structures. The students will also be able to understand the behavior of structures under ultimate and accidental loadings. The students can apply existing theories, methods and scientific insight in the structural engineering field and work independently. The students may develop advanced skills in structural analysis and design, critical evaluation and solving critical issues of steel structures such as multi-story buildings, long-span bridges and marine/offshore structures. In addition, the students should be able to recognize various types of collapse mechanisms, fracture models, caused by structural damages, deterioration, and fatigue. The students should also obtain knowledge in monitoring, maintaining and repairing of the damaged steel structure.
Required prerequisite knowledge
BYG530 Plastic Analysis of Structures, BYG550 Structural Dynamics, MSK540 Finite Element Methods, Advanced Course
75% av obligatoriske regneøvelser
A course project and 75% of the compulsory assignments must be approved in order to take the exam.
Method of work
6 hours of lectures and 2 hours tutorials per week. Compulsory assignments.
Exchange programme at Faculty of Science and Technology
There must be an early dialogue between the course coordinator, the student representative and the students. The purpose is feedback from the students for changes and adjustments in the course for the current semester.In addition, a digital course evaluation must be carried out at least every three years. Its purpose is to gather the students experiences with the course.
