SummaryThis course engages students with the fundamental principles of Structural Mechanics relevant to civil and mechanical engineers. Specific topics including: equilibrium, stress, strain, axial load, torsion, bending, shear, and deflections in structural elements including beams, columns, struts, ties, and trusses.
Course description T1 Introduction and Overview: Course structure and organisation. What is structural mechanics?┐┐

T2 Structural forms: Structural elements and examples. Strength and stiffness. Loads.

T3 Global Equilibrium: Forces and moments, point and distributed loads. Support conditions. Global equilibrium of structures. Concept of structural determinacy and indeterminacy.

T4 Free Body Diagrams and Stress Resultants
Truss equilibrium. Stress resultants in struts (axial load), shafts (torsion), beams (shear and bending) and pressure vessels (membrane forces).

T5 Members carrying Axial Load

T15 Shear Stresses in Beams (1)
Complimentary shear. Derivation of shear stress formulae.

T16 Shear Stresses in Beams (2)

Learning Outcomes
On completion of this course, the student will be able to:
  1. Describe and manipulate fundamental concepts of stress, strain, and deformation in members carrying axial, bending, shear, and torsional loads;
  2. Determine how statically determinate trusses and beams carry load; for beams using diagrams of bending moment and shear force, and evaluate the resulting elastic deflections of the beams;
  3. Analyse structural cross sections, so as to determine the elastic stress and strain distributions, as well as the deformations, resulting from axial, bending and torsional actions; and
  4. Describe and manipulate relevant concepts of combined loadings and stress and strain transformation.
