CE249 Students Conduct Bridge Test to Evaluate Structural Integrity

Last Friday, students from CE 249, an "Experimental Methods in Structural Engineering Class" taught by Professor Khalid M. Mosalam, conducted a test on the sixth-floor outdoor bridge of Davis Hall to investigate the behavior of the structure. They evaluated the bridge's condition at different intervals using a computer to get the frequency data points and other measures. Students recorded several data points to measure the force exerted by jumping simultaneously together in the middle of the bridge, using a rubber hammer to strike the bridge at focal areas of the bridge, and walking simultaneously across the bridge.

This course covers the following topics:

  • Similitude laws, design of structural models, instrumentation, and measurement techniques.
  • Use of computers to acquire data and control tests.
  • Pseudo-dynamic testing method.
  • Standard proof-testing for capacity assessment.
  • Non-destructive testing for condition assessment and virtual experimentation.
CE 249 students are practicing walking in sync together to collect frequency data points from the bridge.

Students are waiting in between a trial to see what collected data points are from the computer.
