# Steel Structures

## Code

CE-STU1

## Version

4.0

## Offered by

Civil Engineering

## ECTS

5### Prerequisites

Basic knowledge about structural design and steel design, which includes as minimum

• Global stability in buildings.

• Statical analysis and the connection between structures and static calculations.

• Determine loads on buildings and structures according to Eurocodes

• Basic static for beams, columns and frames.

• Basic principles and methods of the elastic strength of materials and deformation calculations

• Stress analysis of structural elements

• Have knowledge about cross-sectional capacity checks for steel according to Eurocode 3

### Main purpose

### Knowledge

– Have knowledge about different types of steel structures (e.g. industrial buildings, hangars).

– Have knowledge about the principles for calculation of plate elements with stiffeners and be able to calculate a chosen few.

– Have knowledge about the resistance of transverse forces (design resistance of webs in plate girders).

– Have knowledge about flange induced web buckling.

– Have basic knowledge of fire design for structural steel.

– Have knowledge of various steel connection types.

– Have a basic understanding of load transfer in steel connections.

### Skills

– Be able to model globally stable structural steel systems.

– Be able to calculate buckling of plates, eg. in welded plate girders.

– Be able to calculate cross sections in class 4 using the effective cross section in the ultimate limit state.

– Be able to calculate a plate girder with respect to lateral torsional buckling.

– Analysis of bracing systems which are required to provide lateral stability of beams and compression members (eg. columns).

– Be able to calculate restraint in structural parts subject to compression.

– Be able to analyse/calculate some chosen structural steel connections (eg. welded connections in portal frames, design tension resistance of a T-stub flanges in plate girders).

### Competences

### Topics

### Teaching methods and study activities

Activities vary between theoretical lectures, self-studies, consultation periods in connection to the work with assignments and students presentation of assignments.
