Displacement Monitoring of I-35W Bridge With Current Vibration-Based System

Status:  Complete
Report Date:  02/01/2019

Summary:

Researchers developed a new method for estimating vertical displacements on bridges using accelerometers installed on the I-35W St. Anthony Falls Bridge in Minneapolis. The dual-model approach shows potential for using these sensors to measure vertical displacement on steel, cable-stayed and other less-stiff bridges where traffic generates higher vibration frequencies. The method expands the industry's knowledge of how to use smart sensors in new ways.
