LEARNING OUTCOMES  

The students attending this course gain the basic knowledge of the Design and Analysis of Steel Structures and Limit State Design. This knowledge is necessary as interpreting the current EC3 Code, students will be capable of examining data of simple or composite structures, combining and composing the necessary adequate means and design criteria. Furthermore, students will be able to classify steel cross-sections according to EC3, to identify different loadings such as axial, flexural, shear, torsion, as well as their combinations in order to determine strength, deformations and displacements of steel joints and elements. During the course, there will be held lectures of: General introductory elements in the steel structures. Static analysis of indeterminate structures – Exercises. Stress analysis of determinate and indeterminate steel structures. Introduction to Eurocode 3 and steel structures. Classification of cross sections, Load classification, Connections (Welded Connections – Bolted Connections). UIT technology, Design of connections, braces and structures, Design Criteria, Behavior of steel X-braces in buildings. Fire protection and corrosion protection. Examples of structural analysis using professional codes. Plastic Load Capacity, Plastic Analysis, Failure Mechanisms of steel frames and Applications.

The learning outcomes of this course correspond to the descriptive indicator 8, according to the European Qualifications Framework.
