3.2 Structural Application

In shell structures (e.g., free-form concrete roofs), IGA avoids the curvature errors of faceted meshes. A study by Cottrell et al. (2009) showed that IGA achieves comparable accuracy to quadratic FEA with 80% fewer DOFs.

  • From micro-mechanics (e.g., fiber-reinforced composites) to macro-elements
  • Coupled thermal-structural and fluid-structure interaction (FSI)

Advanced modeling techniques have transformed structural design from a series of conservative approximations into a precise science. By leveraging nonlinear analysis, FEA, and parametric optimization, engineers can create safer, more sustainable, and more ambitious structures. As computational power continues to increase, these "advanced" methods will soon become the standard for every modern engineering firm.

4. Computational Fluid Dynamics (FSI) – Fluid-Structure Interaction

Wind engineering has moved beyond static equivalent wind loads. Using CFD, engineers model the actual wind field around a building. From micro-mechanics (e

4. Time-dependent and dynamic modelling

  • Transient dynamic analysis: explicit vs implicit integrators; explicit suited for highly nonlinear, short-duration events (impact, blast); implicit for longer-duration, quasi-static or moderate-rate dynamics.
  • Modal and response-spectrum analysis: linear modal decomposition for seismic design; caution: modes may change in nonlinear range.
  • Time-history (nonlinear dynamic) analysis: realistic seismic response, including soil-structure interaction and near/far-field ground motion scaling.
  • Creep, shrinkage, and long-term behavior: viscoelastic/viscoplastic models for concrete and other materials; incorporate age-dependent stiffness and time-stepping schemes.
  • Fatigue and fracture mechanics: cycle-dependent damage accumulation models, cohesive-zone modelling for crack propagation.
