Advanced Analysis and Design of Steel Structures

This is the study programme for 2020/2021.

The course mainly provides an advanced knowledge, principles and computer aided tools for analyzing, designing and maintaining of civil and offshore steel structures. The course covers analysis and design philosophies in all the structural design limits states/situations such as ultimate, serviceability, fatigue and accidental.

Learning outcome

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.


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.
  • Design of tubular members and tubular joints for ultimate loads according to NORSOK N-004. Introduction to steel shell structures and design guidelines to the Eurocode.
  • 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. Case examples for non-linear multi-story buildings/offshore jacket structures. (Computer aided case study assignment)
  • Elastic analysis of complex joints and design of joint components according to Eurocode.

Analysis and design for accidental actions
  • Overview of accidental loads to civil and marine structures.
  • Accidental actions from ship collisions with fixed and floating bridges, offshore platforms and other ships. Structural design against accidental loads according to codes and guidelines including NORSOK N-004, DNV RP and Eurocode.
  • Structural response analysis of dropping objects impact and explosions. Design philosophy and method with reference to various design standards are presented.
  • Case examples for collision and impact loads using LS-DYNA. (Computer aided case study assignment)
  • Nonlinear, time-domain simulation of fixed and floating structures subjected to earthquake and tsunami loads using Abaqus or USFOS.

Analysis and design for fatigue (Group project and presentation)
  • 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.

Structural health monitoring of steel structures (Group project and presentation)
  • General concepts in structural health monitoring of structures including fields of applications
  • Structural health monitoring methods, data acquisition, structural properties extraction, structural condition evaluation, and damage detection.
