Vibrations in Structures

Greg McLaskey

Assistant Professor
Cornell University
School of Civil and
Environmental Engineering

In this lab session, students were introduced to vibrations in structures ranging from the Earth to buildings and bridges to electric guitars. Students learned about resonant frequencies of vibration, modal shapes, and how to measure those vibrations with sensors, and visualize the vibration measurements with computer software. Students participated in a field test involving the vibrations of the Duffield Hall stairs on the engineering quadrangle.
