Aim
The course Structural Design shall give

• basic knowledge on structural design.

• practice in solving engineering problems.

• give a comprehensive view of the interaction between mechanics, structural mechanics and structural engineering.

• practice in reporting results.

• understanding that the design of buildings, in addition to structural aspects, shall take into consideration a number of aspects such as economy, aesthetics, indoor environment and enviroment.

The Structural Mechanics part shall give

• knowledge about concepts, models and analysis methods within the field.

• practice in reasoning about the relation between physical object and model.

• ability to solve engineering problems within the field.

• knowledge and skill in analysing and designing components and structures.

• knowledge about actions and how they are treated in practice.

• knowledge about how the choice of material affects the behaviour of components and structures.

Contents
Structural Mechanics:

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. Transformation of stress and strain, principal stresses, yield criteria. Dynamics; free vibrations and response to harmonic loading for simple structural elements.

Structural Engineering:

Principles of design, safety principles, actions on structures. Elements in the structure. Stabilisation of structures. Structural materials: steel, wood, concrete and masonry. Design for bending moment, axial force, simultaneous moment and axial force, shear, deformations and vibrations. Structural design of details, connections and joints. Fire safety.
