CIVIL-449 / 6 crédits

Enseignant(s): Beyer Katrin, Lignos Dimitrios, Saloustros Savvas

Langue: Anglais


Summary

This course provides an introduction to the nonlinear modelling of civil engineering structures.

Content

The course is based on assignments in which students either implement the nonlinear analysis from scratch (for models with truss elements) or use an open-source software (for models with beam elements). The topics that are covered are the following:

  • Truss models: Hand calculations and finite element calculations of truss models with material and geometric nonlinearity; Nonlinear material laws: Plasticity
  • Beam element formulations: Total and incremental compatibility and equilibrium relations of beams, accounting for large displacements. Differential equations for Euler-Bernoulli and Timoshenko beams. Sectional analysis of RC sections. Beam formulations with concentrated and distributed plasticity approaches (force-based and displacement-based).
  • Nonlinear analyses: Solution methods for nonlinear static and dynamic analysis. Damping models.
  • Review of past blind prediction tests and comparison between numerical and experimental results.
  • Use of nonlinear simulations in civil engineering practice.
