Project DescriptionProject Description
Need for introduction to dynamic behavior and earthquake engineering at the undergraduate level
Large scale shake tables require significant resources and are not widely available.
Development of experiments takes time and expertise

ConclusionsConclusions
UCIST is a lab station for “hands on” experimentation in earthquake engineering
Many experiments are already available
Also, used for outreach and research
