Abstract

The bridge over the Arno River built in the late 1980s, located at the boundary of a seismic zone, has been instrumented with a large number of transducers of different types, for a total of 354 measuring points. The variables monitored are: vertical load on the bedrock, stresses and temperatures in the concrete, inclinations of the piers, vertical load on the bearings, and displacements in the expansion joints. The installation of the transducers was carried out simultaneously with the different phases of the erection of the structure and the values of the monitored variables were measured throughout the period of construction and the following two years of service. Measurement data, analyzed and compared to design data, permitted the acquisition of important information on the actual process of concrete curing and the settling in of the structure, both under the influence of job site operations and the ensuing normal service loads.
