Course Description

Hybrid simulation is a set of methods for examining the seismic response of structures using a hybrid model comprised of both physical and numerical sub-structures. This workshop on hybrid simulation is for NEES researchers, both current and future. Attendees will: 

  1. Learn the basics of hybrid simulation methods.
  2. Learn about OpenSees and OpenFresco.
  3. Conduct a hybrid simulation at the nees@berkeley Equipment Site.
  4. Be able to use hybrid simulation in their NEES and non-NEES projects.
  5. Prepare to develop new hybrid simulation tests and algorithms.

We will review the basics of hybrid simulation, including similitude requirements for model design, model implementation including integration methods, and simulation result interpretation. Then, we will demonstrate how hybrid simulation is implemented at nees@berkeley using our hardware and OpenSees and OpenFresco software. The attendees will have a unique opportunity to develop a hybrid model and, with the help of our staff, implement and run a hybrid simulation at nees@berkeley. Throughout the workshop we will demonstrate how to use the nees@berkeley Equipment Site hardware and software portfolio and how to process and archive hybrid simulation data. In addition, an overview of nees@berkeley's capability in conventional (non-hybrid) testing with sophisticated multi-axial control will be presented.

See the workshop agenda for additional information about content and activities.

Application Procedure

Please apply using the online registration form by February 15, 2011. A $50 workshop fee is required to attend the workshop.

You may pay with a credit card when you register, or pay with check or cash on the first day of the workshop. No credit cards will be accepted on the day of the workshop. If paying by check, make the check payable to “The Regents of the University of California” and bring it on the first day of the workshop.

Please provide your email address so we may contact you about any updates or changes.

Travel Support

Pending NEEScomm approval, limited travel support may be available for graduate students, young post-doctoral researchers, or tenure-track faculty at US schools. To receive reimbursement for airline travel, you must comply with the Fly America Act (use a US flag carrier). See our travel support policy webpage for detailed requirements to qualify for reimbursment of travel expenses.


The workshop will be held at the nees@berkeley Equipment Site located at UC Berkeley's Richmond Field Station (RFS). On both days, the workshop will provide two meals (continental breakfast and light lunch) and refreshments at two coffee breaks (one morning and one afternoon). In the evening of the first day, Thursday, February 24, there will be a workshop dinner on or near the Berkeley campus.

For information on getting to RFS, see the transportation section below.

Workshop Location

The workshop will be held at the nees@berkeley Equipment Site located at UC Berkeley's Richmond Field Station (RFS).

UC Berkeley — Richmond Field Station
1301 South 46th Street
Richmond CA 94804

Building 484 nees@berkeley Equipment Site (Lab)
Building 451, Room 19 “Conference Room” (Lectures)


For accommodations, we suggest you consult the UC Berkeley list of local accommodations to find information about hotels and motels in the area.

Unlike past years, we were not able to arrange any group rate discounts at nearby hotels. In addition, we discovered that hotels near campus are sold out on Friday night (Friday is the last day of the workshop). So if you planned to stay Friday night, you might need to change hotels or to stay someplace other than Berkeley.

Local Transportation

For transportation from the Berkeley campus and adjacent downtown area (where many hotels are located) to the Richmond Field Station, your best bets are drive, take a taxi, or take the UC Berkeley “RFS Line” shuttle.

  • Driving. Maps and directions to the Richmond Field Station are available from the website.
    Parking at the Richmond Field Station costs $0.50 per day.

  • Taxi. Take a taxi and NEES will reimburse the taxi fare.

  • “RFS Line” Shuttle. The UC Berkeley Parking and Transportation unit operates the “RFS Line” shuttle between the main campus in Berkeley and the field station in Richmond. For more information, check the schedule and route of “RFS Line” in the shuttle webpages.
