Shake Things Up!
25 Nov 2014 | Learning Objects | Contributor(s): Sandra Seale, Joe Paul Trudeau, Hanna Vincent, NEES EOT
This activity will educate students about earthquakes and vibrations using a shake table and the Quake Catcher Network (QCN) device. This experiment asks students to graph data for the interpretation and study of earthquakes. Shake tables are useful tools for testing structures. By simulating...
NEES@RPI Sensor Videos
25 Nov 2014 | Multimedia | Contributor(s): NEES EOT
Sensors are a critical component of physical modeling. They produce information that is used to quantify and understand physical phenomena. The centrifuge facility at Rensselaer Polytechnic Institute uses many types of sensors and instrumentation. The following videos introduce two types of sensors.
Photogrammetry As A Non-Contact Measurement System In Large Scale Structural Testing
25 Nov 2014 | Publications | Contributor(s): Anahid Behrouzi, Daniel Kuchma
Photogrammetry is a non-contact measurement method that is being used in large scale structural experimentation to extract information about the overall geometry of the specimen as well as the XYZ motion of select points on the structure during testing. This is possible through the use of...
