STRUCTURAL MECHANICS | FME602 |

**Aim**

The aim of the course is to give an introduction to structural mechanics with application to types of structures that are common in buildings and infrastructure.

The course is intended as basic general knowledge for a BSc in Civil Engineering and to give necessary prerequisites for further studies in structural engineering and geotechnical engineering.

*Knowledge and understanding*

For a passing grade the student must

- Be able to explain basic concepts and relations within the area.
- Be able to describe the fundamental shape of the stress distribution caused by axial load, bending or torsion in a beam.

*Skills and abilities*

For a passing grade the student must

- Be able to calculate section forces, stresses and deformations for bars, trusses, beams, simple frames, shafts and simple composite structures.
- Be able to analyse columns with respect to buckling and second order theory.
- Be able to present a clear written solution to a problem (given data, assumptions, calculations, results, conclusions).

*Judgement and approach*

For a passing grade the student must

- Be able to assess the reasonableness in an obtained result.

**Contents**

The course starts with a discussion of the concepts of force, moment, free-body diagrams and equilibrium, with application to trusses, and introduction of the concepts stress and strain.

- Free-body diagrams and equilibrium. Trusses. Stress, strain and stress-strain relationships.

- Section forces in beams. Normal stress and shear stress for elastic bending of beams. Plastic bending of beams. Deflection of beams. Statically indeterminate beams.

- Columns; buckling and second order theory. Torsion of circular cross sections.
