Aim
This course will give knowledge about the structural analysis of simple elements subject to axial forces, bending, shear and torsion. The result can be expressed as a stress variation along a span and over a cross section.

Knowledge and understanding
For a passing grade the student must

• Explain and make use of terms like force, load, moment and shear.

• Explain and make use of the mathematical relations between load, shear and moment stress and deformation.

• Explain and make use of Hook´s law with extensions.

Skills and abilities
For a passing grade the student must

• Analyse trusses

• Analyse statically determined beams and vaults

• Analyse statically indetermined beams and frames

• Determine moment and shear variation

• Determine moment of inertia and bending stiffness

• Determine normal, bending and shear stresses

• Determine the Euler buckling load

• Appraise the reasonability of a result

Judgement and approach
For a passing grade the student must

• Present the result of an experiment in a report.

Contents
The course include fundamental parts of classical non-deformable, deformable structural elements and classical strength theory of materials.

Classical non-deformable structural elements include trusses, beams and vaults. Fundamental is the formulation of equilibrium between external and internal forces.

For deformable structural elements deformation relations are added. This makes a general analysis of structurally indeterminate structures possible. This will be applied on simple beams and frames.

The strength theory of materials include applications based on Hook´s law to determine stresses and strains for members subject to tension and compression. Extensions include members subject to bending, shear and torsion. The theory will be applied to simple elements in wood.
