Bridges, being concrete structures, oscillate from excitation with impulsive forces. The details of these oscillations such as amplitudes, frequencies, and their decay coefficients bear information about the structural health of the bridge. Each tire of a passing vehicle excites the bridge with a short impulse of force, which contains a broad frequency spectrum. We developed a mathematical model to describe the resulting oscillations and compared the time response of the model with measurements taken at the deck of a bridge.
