OPENSEES: Open System for Earthquake Engineering Simulation

University of California, Berkeley,

The Open System for Earthquake Engineering Simulation (OpenSees) is a PEER sponsored project to develop a software framework for simulating the seismic response of structural and geotechnical systems. OpenSees is intended to serve as the computational platform for research in performance-based earthquake engineering at PEER. The OpenSees website includes source code, user manuals, examples, links to projects using the software, and resources for developers.
