Portfolio: Structural Analysis, Design and Checking

Scope of Services

Modern numerical simulation techniques allow for a realistic analysis of structural behaviour even for highly complex structures such as long-span bridges. We specialise in the development and application of simulation, validation and visualisation tools for advanced structural analysis.

Employing cutting-edge technology we are able to deliver optimised and reliable structural designs as well as robust assessment of existing structures.

Our firm has extensive experience in simulations of a wide range of structural systems and loading scenarios, with particular specialisation in bridges and dynamic response phenomena. The scope includes:

  • Physically nonlinear analysis of concrete, composite and steel structures
  • Geometrically nonlinear systems, including tensile structures and form finding techniques
  • Linear and nonlinear dynamic analysis, e.g. pedestrian-induced vibration of footbridges, seismic analysis, wind-induced vibrations, cable oscillations
  • Analysis of structural damping devices, e.g. Tuned Mass Dampers, cable dampers, active control
  • Stage-by-stage construction analysis, specifically of long-span bridges
  • Soil-structure interaction analysis
  • Analysis of fire resistance of structural members
  • Heating and ventilation simulations.
