The course is an introduction to structural mechanics and acoustics. It also gives the student fundamental knowledge and experience of importance to most other courses in the civil engineering programme.
Structural mechanics: Stress and strain. Section forces in statically determinate trusses and beams. Tension, compression, bending, shear and torsion. Elastic and elasto-plastic material behaviour. Two-dimensional state of stress. Yield criteria. Deflection of elastic beams. Statically indeterminate and beams. Second-order theory and buckling. Limit state theory. Acoustics: Noise and its effect on human beings. Recommendations and guidelines, description of sound, sound progration, sound insulation, absorption and room acoustics.
