Steel Structures II

Abstract

Theoretical foundation and constructional features of the design and construction of steel and steel-concrete composite structures. Multi-storey buildings and bridges. Structural analysis for steel-concrete composite structures. Plate buckling of unstiffened and stiffened panels. Fatigue resistance and safe life assessment. Detailling, drafting, fabrication and erection, cost estimation.

Objective

Students will expand the knowledge acquired during "Steel Structures I" and learn how to apply these skills to the design of more complex building and bridge steel and composite structures. They will acquire the fundamental background for the phenomena of plate buckling and fatigue and learn how to apply it to practical design tasks. In addition, students will learn to appreciate the importance of questions of detailling, fabrication, erection and cost calculation for the effective design of steel and composite structures. After completion of the year-long course in Steel Structures I+II, students will have at their disposal a wide and detailled set of skills concerning the modern practice for steel and composite structures design and have a deep understanding of its theoretical & scientific background. The examples of scientific and standardisation work provided in the lectures give the students the opportunity to learn about the most current developments and see how these are used to shape the future practice in the structural engineering field.

Content

The lecture Steel Structures II complements the knowledge acquired in part I by providing students with additional theoretical and practical knowledge, e.g. on the design of steel and composite structures against fatigue, plate buckling, as well as on the structural modelling and analysis of more complex building and bridge structures. These more theoretical topics will be exemplified and illustrated by applications to real problems in the design of bridges and multi-storey building structures. Finally, the course will provide detailled insight into aspects pertaining to structural detailling, fabrication, erection and cost estimation for constructional steelwork. Content overview: - Structural forms, analysis techniques and modelling of multi-storey buildings and bridges. - Structural analysis (deformations, internal forces, stresses and strains) in steel-concrete composite girders considering the effects of creep, shrinkage and shear deformations. - Elastic and plastic longitudinal shear transfer mechanisms and effects - Plate buckling of unstiffened and stiffened panels - Fatigue resistance and safe life assessment: phenomenon and design approaches - Special topics of steel connection design - Detailling, drafting, fabrication and erection, cost determination in constructional steelwork
