  • Earthquake simulator tables, or shake tables, are used for experimental research in earthquake engineering.

  • This equipment is capable of reproducing the motion of the ground during an earthquake, allowing for controlled testing of structures subjected to earthquakes.

  • New concepts and techniques are often tested on scaled structures using shake tables before implementation.

  • Bench-scale shake tables offer an ideal mechanism to provide students access to such “hands-on” experiments.

Evaluation program1
Evaluation Program

  • Goals

    • Describe classroom implementation of virtual laboratory

    • Estimate the impact of virtual experiments on student learning

    • Describe associations between gender and patterns in learning

  • 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 another building across campus from you room is amazing.”

Benefits to the students
Benefits to the Students

  • More flexible and complex experiments using multiple sites

  • Experience with cyberinfrastructure

  • Flexible scheduling of experiments

  • Access for students at a larger number of universities to participate in advanced experiments

Implications for engineering educators
Implications for Engineering Educators

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

  • Review resources at NEES and UCIST

  • Think creatively about student experiences in your classroom, especially the extent to which men and women may perceive differences in their abilities that may contribute to differential rates of pursuit of further engineering education.
