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 year's hybrid simulation workshop at nees@berkeley emphasizes real-time loading, including demonstrations of our new “smart” dynamic platform. The workshop is aimed 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 several real-time hybrid simulation demonstrations 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.
  6. Learn about pros and cons (accuracy, limits, ease of use, field applications in damage assessment) of modern non-conventional monitoring and measuring techniques.

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 including several state-of-the-art measurement and data acquisition techniques. In addition, an overview of nees@berkeley's capability in conventional (non-hybrid) testing with sophisticated multiaxial control will be presented.

Case studies of modern non-conventional monitoring and measuring techniques will be presented. These cases will cover a Krypton position monitoring system, high-definition laser scanners, and image correlation techniques and their comparison to conventional instrumentation. The main goal of this discussion will be to provide a detailed background on the techniques, share success stories, and help researchers in selecting the right technique that suits their experimental needs.

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

Application Procedure

The workshop is now full. No more applications are being accepted at this time.

This workshop session is offered at no cost.

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

Travel Support

Limited travel support will 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 reimbursement of travel expenses.

The amount of travel support provided per person cannot be determined until after the Hybrid Simulation Workshop has occurred and everyone has turned in their supporting travel documents. The amount of travel support given to each person will depend on how many people need travel support and the amount that each person needs. Either partial or full travel support may be given to each person requiring travel support.

Logistics

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 coffee breaks (one morning and one afternoon). Note that the workshop ends after lunch on the second day.

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

Richmond CA 94804

Building 451, Room 19 “Conference Room” (Lectures)

Building 484 nees@berkeley Equipment Site (Lab)

Accommodations

Arrangements have been made with the Hotel Shattuck Plaza (http://www.hotelshattuckplaza.com/) at 2086 Allston Way in downtown Berkeley to provide rooms for workshop participants at a discounted rate (in collaboration with the PEER Center). You can book a room in two ways:

  1. Call the Hotel Shattuck at 510-845-7300 (or toll free 866-466-9199) and ask for the PEER (Pacific Earthquake Engineering Research Ctr, UCB) group rate.

  2. Book online at: https://booking.ihotelier.com/istay/istay.jsp?hotelid=17233

    IMPORTANT: To get the group rate you will need to click on the Corporate/Preferred Accounts option at the top left hand side of the page. This will prompt you to enter the courtesy rate code (PEER10). Once the code is entered, the discounted rates and the available room types for the selected dates will be displayed.

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

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 PEER 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. Hotel Shattuck is conveniently located 1/2 block away from the Downtown Berkeley Bart Station and 1 block away from the RFS Line stop at Oxford and Center Street. The RFS Line shuttle will take you directly to where the Hybrid Simulation Workshop will be held.

    • The RFS Line fare is $1.50 each way.

    • For its first run of the day, the RFS Line shuttle departs from the Oxford Street and Center Street stop at 7:42am. Workshop participants should aim to catch that run. Thereafter the shuttle departs that stop every 17 after the hour starting at 9:17am.

    • UC Berkeley's Parking and Transporation unit has webpages with full RFS Line schedule and other information at this URL “http://pt.berkeley.edu/around/transit/routes#day”

We suggest for participants to meet in the hotel lobby of the Shattuck Hotel with other participants and group yourselves into carpools with individuals who have rented cars or taxipools in order to get to the Richmond Field Station.
