Abstract

The water supply net in Friuli Venezia Giulia - Italy, is based on a certain numbers of reservoirs mainly constructed using r.c. elements. In the area of Udine the net is based on differently shaped tanks. The paper is concerned with the analysis of the structural conditions of six of such tanks in the ambit of a strategic project aimed to evaluate their seismic performances in a highly seismic area as the Friuli Venezia Giulia region and, among other aspects, with the identification in operational conditions of their modal characteristics. In fact, the possibility to construct reliable and precise FE models of the analysed structures based on the results of in situ dynamical tests is the main way to carry out the task. For such reasons, the principal purpose of the paper is to obtain a reliable dynamic characterization needed to calibrate the FE models of the structures and to collect reference modal models for possible future damage assessment campaigns.
