OpenFresco (the Open-source Framework for Experimental Setup and Control) is an environment-independent software framework, based on modern object-oriented software design and programming methodologies. The software connects finite element models with control and data acquisition systems in an extensible manner to facilitate conducting local and geographically distributed hybrid simulations of structural systems.

This seminar is the continuation of an earlier seminar on OpenFrescoExpress. This second seminar will provide a short introduction to the hybrid simulation testing technique and the architecture of OpenFresco. It will then illustrate how OpenSees/OpenFresco can be used to setup and execute more complicated hybrid models than what can be done with OpenFrescoExpress. The following topics will be covered:

  • Introduction to hybrid simulation
  • OpenFresco architecture and TCL commands
  • Downloading and installing OpenFresco
  • Building a hybrid model in OpenSees/OpenFresco
  • Simulated versus real controllers
  • How to use other computational drivers
  • Summary and conclusions
