The course covers the more advanced common topics in steel design. These are elastic bending of plates, theory for elastic buckling of axially loaded and shear loaded plates, cross-sectional classes, capacity of plates and plated structures, stiffeners in beams and at supports and at concentrated loads, advanced cross-sections, modeling and stiffness and capacity of joints in building frames, lateral torsional buckling of beams, torsional buckling and torsional-flexural buckling of columns. Further topics are behaviour of steel structures exposed to fire and design for fatigue loading. The course gives examples of structures and components and practices how to design large steel beams, thin walled sections, stiffened plate elements, bridge box cross-sections, joints and structural frames.
Steel Structures 2 continues steel design topics dealt with in Steel Structures 1, covering more advanced structural elements and applications, and aiming for a wider field of application. The course presents the theory for elastic bending of plane plates and for plate buckling, capacity models for plates and plated components, lateral torsional buckling of beams and design of bracing systems. Further topics are design for fire resistance of steel structures and design for fatigue loads. Steel Structures 2 has these learning objectives: Knowledge about: - Calculation of capacity and load resisting mechanisms for cross-sections and structural elements. - The theory for elastic plate bending and plate buckling, for in-plane axial force and shear force. - Effect of stiffeners on plate buckling behaviour, effect of elastic restraints, and buckling for concentrated loads on plate edge. - Torsional effects for members and cross-sections. Torsional buckling and torsional flexural buckling for columns - Elastic lateral-torsional buckling for beams , with effect of load case and moment distribution, load application height and mono-symmetry of cross-section. - Behaviour of steel at elevated temperature in fire, fire conditions and fire design. Design for fatigue. - Capacity for joints in buildings, bolted and welded solutions, frame corners, strengthening with stiffeners, classifications of joints for structural analysis, and how to choose structural model. Skills: - Calculate capacity for sections and members with standard cross-sections or thin walled sections made from plate parts, included stiffeners, following the rules of Eurocode 3 and accepted design formats. - Calculate lateral torsional buckling resistance of beams, and capacity of slender beams with elastic restraints from connected elements. - Calculate capacity and behavior of simple joints, bolted or welded, and classify and model these for structural analysis. - apply computer programs for plate buckling and lateral torsional buckling General competence: - The theoretical basis for analysis and design of components as beams and columns in steel, for all cross-sectional shapes and components used in steel structures, and for all relevant instability and failure- modes. - Understand and apply the provisions and formulas for design, as given for instance in Eurocode 3, and to know the scope of the rules. - Design advanced steel components and structures, and verify capacity.
Learning methods and activities
Lectures and weekly exercises, laboratory building project with design, construction and testing of a truss structure made from aluminium profiles. 2/3 of the assignments must be approved prior to the examination. The lectures and exercises are in English when students who do not speak Norwegian take the course. If the teaching is given in English the Examination papers will be given in English only. Students are free to choose Norwegian or English for written assessments.
- Exercises, laboratory activities
Further on evaluation
If there is a re-sit examination, the examination form may be changed from written to oral.
