Synopsis:

Subject YSMK covers two parts. The first one deals with stability and strength of steel plates, the second one with stability and strengths of steel frame structures.

In the first part the historic collapses of steel structures are analysed including the importance of imperfections for a design of thin plated structures. Presented are principles of theory of buckling, linear and nonlinear theory of buckling of thin plates. The results are applied to the 4th class cross sections in harmony with Eurocode. Buckling due to normal, shear and local loadings including their combination is analysed in a detail. In the end the application of the results is shown together with design of necessary stiffeners.

The second part is focused on member and structure stability. Possible global analysis methods are presented together with methods for compression and bending interaction for slender members. In detail, specific cases of lateral torsional buckling are explained including also tapered members.

Requirements:

No prerequisities.

Syllabus of lectures:

1. Introduction, lessons from collapses of structures. Classification of cross sections. 2. Principles of buckling theory. Linear buckling theory. Differences in behaviour of struts and plates. Imperfection of panels and stiffeners. 3. Nonlinear buckling theory of imperfect plates. 4. Application of results to 4 class cross sections. Stiffened plates. Task. 5. Flanges of girders in compression. Webs loaded in shear. Buckling in shear. 6. Strengths in shear. Local loading of girder webs. 7. Application of results, interaction of buckling in shear and moment. Design of web and flange stiffeners. 8. Stability and load capacity of slender members and structures. 9. Resistance of beams subjected to lateral torsional buckling. 10. Compression and bending interaction for slender members. 11. Global analysis methods. 12. Global analysis methods and resistance calculation according to the Eurocode. 13. General method.

Syllabus of tutorials:

1. Assessment of a bridge box girder with the 4 class cross section.

2. Design of a portal frame members considering different methods for global analysis.
