Context for Simulation in Earthquake Engineering
- Research and practice is moving towards Performance-Based Seismic Engineering, which depends on high-fidelity models and simulation to assess performance.
- Simulation models capture knowledge from tests to leverage investment in limited experimentation.
- Community-based, open-source software for simulation promotes innovation in research and advanced applications for practice.
- NEES infrastructure is supporting OpenSees to provide simulation capability and integration with NEESit services for NEES research.
What is OpenSees?
- A software framework for simulation applications in earthquake engineering using finite element methods. OpenSees is not a code.
- A communication mechanism for exchanging and building upon research accomplishments.
- As open-source software, it has the potential for a community code for earthquake engineering.
