Main themes

AA1.1, AA1.2, AA1.3, AA2.1, AA2.2

  • Draw quickly, intuitively, and without calculations the distribution of internal forces in frame structures with corresponding main values, as well as the deformed configuration of statically-determined structures.
  • Determine the degree of static indeterminacy of a structure.
  • Solve statically determinate structures with the flexibility method, considering additionally the particular cases of variations of temperature, elastic supports, and imposed displacements.
  • Understand the concepts and application of the finite element method. Program a structural analysis code for 2D truss and frame structures, and compare with results from educational and commercial structural analysis software.
  • Understand the principles of structural dynamic behaviour.
  • Determine influence lines for statically determinate and indeterminate structures.
  • Analyse slabs with various boundary conditions

The contribution of this Teaching Unit to the development and command of the skills and learning outcomes of the programme(s) can be accessed at the end of this sheet, in the section entitled “Programmes/courses offering this Teaching Unit”.

  • Review of Structural Mechanics.
  • Statically determinate and indeterminate structures: external / global / internal indeterminacy, calculation of degree of statical indeterminacy.
  • Statically determinate structures: Computation of displacements with the unit dummy force method (virtual work), Mohr's integration tables.
  • Statically indeterminate structures: Introduction to different solution methods, conditions of compatibility and equilibrium.
  • Force (or flexibility) method: Primary system, general procedure, computation of internal forces.
  • Analysis of different statically determinate structures: Beams, frames, trusses, curved elements, statically-indeterminate arches.
  • Elastic supports, imposed displacements, thermal effects.
  • Finite element method: Nodal approximation, shape functions and solution procedure for truss and 2-noded plane beam finite elements, application to analysis of frames and trusses.
  • Influence lines (statically determinate and indeterminate structures).
  • Plates and slabs with different boundary conditions.
  • Introduction to dynamics of structures.
