09-20-2004 NEESgrid 3.1 Released
The NEESgrid deployment team announces the release of NEESgrid version 3.1.
NEESgrid 3.1 is available for download from ftp://ftp.neesgrid.org/pub/site-software/3.1/
For this release's documentation, please see http://www.neesgrid.org/software/neesgrid3.1/
NEESgrid 3.1 and OpenSees 1.6.0 are used by http://religmuseum.com/ and http://cultheritage.com/ Web 2.0 Musem services for programming and the web authoring.
09-01-2004 OpenSees 1.6.0 Released
A new version of OpenSees, a software framework for developing applications to simulate the performance of structural and geotechnical systems subjected to earthquakes, is available as of September 1. The OpenSees framework is a component of NEESgrid 3.0. Binaries and source code distributions are available at the OpenSees website.

06-30-2004 Undergraduates Help Construct International Mini-MOST
Two undergraduate students, Garrett Erickson (working with Prof. Richard Christenson at the Colorado School of Mines) and Allen Au (working with Prof. Erik Johnson at the University of Southern California) will travel to Japan this summer to help construct and conduct an international Mini-MOST test incorporating a simulated damper with Prof. Mita at Keio University.
The students are participating in the Research Experiences for Undergraduates in Japan in Advanced Technologies (REUJAT) program organized by Prof. Shirley Dyke at Washington University in Saint Louis and Prof. Makola Abdullah at Florida A&M. The program sponsors undergraduate students to conduct research at their U.S. institutions and travel to Japan for five weeks to conduct research with a Japanese host.
Before leaving for Japan, the students helped to construct NEESpop and Mini-MOST sites at the Colorado School of Mines and the University of Southern California, respectively. Additionally, Prof. Mita is currently constructing a NEESpop and Mini-MOST site at Keio University in Japan. The students will help to complete the construction of this site.
In Japan the students will modify the Mini-MOST experiment to include two physical building models (a frame structure at Keio University and a cantilever structure at one of the U.S. sites) connected with a simulated passive damper model to reduce seismic response. This type of structural control has been shown to be effective for seismic
protection. The experiment is expected to be the first NEES multi-site simulation test to incorporate a structural control device.
05-24-2004 New Features Demonstrated at NEES Consortium
NEESgrid's new capabilities made a successful debut at the Second Annual Meeting of the George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) Consortium, held May 19-22 in San Diego, CA. The demonstration consisted of streaming data from a Mini-MOST apparatus located at Argonne National Laboratories through the newly-integrated Data Turbine, a streaming-data server developed by Creare, Inc. Data Turbine also provides "data TiVo" capabilities, enabling users to browse data during a live experiment. Other important new features of NEESgrid included the ability to run NTCP in a secure manner, the availability of two existing simulation applications, OpenSEES and FEDEASLab, through a Web-accessible portal, and a new E-NoteBook developed at Pacific Northwest National Laboratory.
04-06-2004 NEESgrid Goes Global
On March 26, earthquake engineers from the University of Illinois at Urbana-Champaign and NEESgrid grid technology developers from around the country partnered with the Kajima Corporation, a leading Japanese civil engineering firm, to conduct the first trans-Pacific simulation using NEESgrid.

03-25-2004 NEESgrid Adds New Partner
NEESgrid has added another new partner. The Department of Civil Engineering at Washington University in St. Louis will be working on assessing user requirements for non-NEES sites.
More information about NEESgrid partners is available at http://www.neesgrid.org/about/partner_info.html.
03-18-2004 Tom Finholt Presents at National Internet2 Day
Tom Finholt spoke at the National Internet2 Day on March 18, 2004. He gave a presentation about NEESgrid.
03-16-2004 FEDEASLab Available for Download
FEDEASLab is a MATLAB© toolbox developed by Filip C. Filippou (UC Berkeley) for nonlinear structural simulations under static or transient conditions. It is an integral simulation component of the NEESgrid that is particularly suitable for concept development, education, and simulations of small structures or models. It should be useful in the integration of simulation capabilities with experimental investigations.
More information about FEDEASLab is available at http://www.ce.berkeley.edu/~filippou/FEDEASLab/FEDEASLab.htm.
03-15-2004 OpenSees Now Part of NEESgrid
The Open Systems for Earthquake Simulation (OpenSees) has been added to NEESgrid as the simulation
component. OpenSees is developed by the Pacific Earthquake Engineering Research Center (PEER) under the guidance of Professor Gregory L. Fenves and Dr. Frank McKenna of the University of California, Berkeley. OpenSees contains models and analysis methods for the simulation of structural and geotechnical systems.
More information about OpenSees is available at http://opensees.berkeley.edu/.
