What is OpenSees?
• A open-source software framework for building structural and
geotechnical (numerical) simulation applications in earthquake
engineering using finite element methods.
• A communication mechanism for exchanging and building upon
research accomplishments.
• OpenSees as been supported by the Pacific Earthquake Engineering
Research Center (PEER) since 1997 and George E. Brown Network
for Earthquake Engineering Simulation (NEES) since 2003.
Parallel&Distributed
Used Worldwide
Usage of OpenSees on NEEShub
shows similar pattern
Outline
• What is OpenSees
• OpenSees Training and Outreach
• OpenSees Code Developments
Discovering OpenSees
• Each presentation done twice: once to facilitate those in US and European countries and
the other for researchers in China and Asian countries.
• Links to these recordings are provided on the Discovering OpenSees series on NEEShub.
