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



HistoryProposed at 1998 Trilateral Earthquake Center Education Meeting MAE Project ED-9: Instruc. Shake Tables NSF – DUE/CCLI Funding Obtained (DUE Grant No. 9950340 – Aug 1999)Consortium became operational summer 2000 under direction of Shirley Dyke
