Abstract:This report provides information on a study of the Arrigoni Bridge in Middletown, Connecticut,
where vibration measurements are used to determine the tension among various suspender
cables in the structure. Actual vibration data on 134 cables under ambient, traffic-induced
excitation is used to determine the corresponding natural frequencies and, along with cable
parameters, calculate the tension in each cable.
