3. NEES Resources Field Equipment Laboratory Equipment Remote Users Remote Users: ( K-12 Faculty and Students) Instrumented Structures and Sites Leading Edge Computation Curated Data Repository Laboratory Equipment Global Connections ( Faculty, Students, Practitioners) Simulation Tools Repository

4. Existing state-of-the-art cyberinfrastructure tools developed by NEESit, the technical support and development component of NEES, have been developed recently for teleparticipation and teleoperation. We plan to take advantage of these capabilities to educate the next generation of civil engineers! Introduction

5. Outline Objectives of the Collaboratory Lab Station Components –Equipment –NEES Implementation Instructional Materials Available –Freshman Level Undergraduate Module –Evaluation Plan Closing

6. Objectives of the Collaboratory To provide engineering students –an understanding of structural dynamics –experience with modern laboratory equipment and instrumentation –exposure to NEES and the latest capabilities regarding remote testing teleparticipation tools –provide a mechanism for training students to perform experiments –opportunities for K-12 outreach

7. Objectives of the Collaboratory 2 Lead Institutions –develop 2 initial exercises –evaluation & adapt 5 Deployment Sites –implement 2 exercise –develop new exercises Available to users

8. Lab Station: Overview

9. Lab Station: Activities University of California, Berkeley Model Shake--Aftermath

10. NEES: Teleparticipation Viewing and analysis of streaming data and video over the internet Enable researchers to remotely participate experiments Allow for classroom demonstrations and hands-on experimentation on physical structures

11. NEES: Teleoperation Remotely controlling the UCIST shake table using the NEES cyberinfrastructure tools Facilitate new testing methods such as distributed hybrid testing To allow remote user (students) to control hands-on experimentation on physical structures

14. Introduction to Earthquake Engineering: Spring 2007 Freshman Engineering module developed at the University of Connecticut

15. Instructional Materials Students learn necessary mathematics to study the forced and free vibration of a single-degree-of-freedom structure A 1-story seismically excited shear frame is used to apply their new knowledge

16. Instructional Materials Overview (Freshman Level 3 weeks) –Earthquake Engineering Introduction –SDOF Equations of Motion –Programming in Matlab –NEES Introduction –Teleparticipation & Teleoperation of Actual Experiment Each student is required to submit weekly homeworks and a final lab report including a discussion of observations and results

17. Instructional Materials Evaluation & Feedback –On-line surveys conducted to obtain student input –Evaluation expert is part of the project Comments –“[It] Was very hands on, and many people learn better by doing and seeing than just calculations” –“It was a very interesting experience. The fact that you could manipulate a structure in an-other building across campus from you room is amazing.”
