Introduction
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!
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
Lab Station: Overview
Lab Station: Activities

Model Shake--Aftermath
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
NEES Implementation
At the University of Connecticut

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.”
