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

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