Version 2.4.0 of the OpenSees binary
available for download. Here is the change log
The next seminar in the web-based Discovering OpenSees: Surfing the
waves of OpenSees
learning series will occur March7.
The session will be broadcast twice at times that will allow users
in all time zones around the world to participate.
This session is titled: Conducting Hybrid Simulations with OpenSees/OpenFresco
and will occur on March 7'th at 9.00 AM and again at 5.00 PM Pacific Time.
The material for OpenSees Days 2012 workshop can be found here
. Videos of the workshop are being prepared and will be posted when finished.
This year we will be awarding two prizes:
Rules & conditions
- an iPod to the developer of the best OpenSees powered tool
added to NEEShub between the OpenSeesDays 2012 and the OpenSees Days 2013 events.
- an iPod to the developer of the best new code development
submitted to OpenSees between the OpenSeesDays 2012 and the OpenSees Days 2013 events.
OpenSees team members presented at
OpenSeesDays, Rome, Italy
on May 24-25 2012.
OpenSees is now available for use to all on
through the OpenSeesLab
tool. For those of you with large models or many runs to perform, the machines on which this tool runs is very very very fast
I have posted a YouTube video showing how to perform an OpenSees simulation using this tool. An improved version will be available soon.
The OpenSees GUI applications, BuildingTcl and OS Navigator, are also available to run.
Try them out, registration and use of the machines are free!
Welcome to the website for OpenSees, a software framework for
developing applications to simulate the performance of structural
and geotechnical systems subjected to earthquakes.
The goal of the OpenSees development is to improve the modeling
and computational simulation in earthquake engineering through
OpenSees is under continual development, so users and
developers should expect changes and updates on a regular basis.
In this sense, all users are developers so it is important to

The development and application of OpenSees
is sponsored by the
Pacific Earthquake Engineering
Research Center through the
National Science Foundation
engineering and education centers program.
OpenSees has been selected as the simulation component for the George E.
Brown, Jr. Network for Earthquake Engineering Simulation
and is being sponsored by NEEScomm . NEEScomm provides support
for the ongoing maintenace of OpenSees and support to integrate OpenSees with the IT and EOT resources that NEEScomm makes available to the earthquake engineering community.
