Introduction

• Experiments are especially valuable for learning fundamental concepts

• Shake tables are excellent learning tools for earthquake engineering

Goals

• To provide opportunities for students worldwide to use tele-operated shake tables for learning

• To support faculty interested in utilizing these learning tools with instructional and technical assistance

Additional Opportunities

• Any class, any size, anywhere!

• Experience with modern laboratory equipment and instrumentation

• Exposure to NEES

• A mechanism for training students to perform experiments

• Opportunities for K-12 outreach

Shake Table Lab Station

Technical Support

• Remote experimentation capabilities using existing cyberinfrastructure tools to – Operate the shake table over the internet – View video and streaming data

Instructional Support

• Provide for remote experiments – Lab manuals– Associated learning materials– Scheduling support – Assessment tools

• Experiments available now – SDOF earthquake engineering module (freshman)– SDOF exercise in frequency domain analysis (senior)– MDOF exercise to design a vibration absorber (senior)

• Facilitating – More versatile learning opportunities– Broadened participation

Instructional Support (Demo)

• Exercise: Design of a Vibration Absorber– Two DOF building model– Passive device to reduce responses– Design length of pendulum and additional mass– Verify performance using teleoperation
