in this study, we concentrate on global health monitoring issues. Global health monitoring has been the traditional tool used to determine the safety of bridges. This technique is based on changed in frequencies and other modal parameters. However, there are several drawbacks of this technique like insensitiveness for initial damage and different frequency changes at same damage level for different location in the structure. In present search work, these drawbacks of global dynamic technique have been improved. For insensitiveness, PZT sensors were used on place of traditional sensors like accelerometer and strain gauge to real data that collected from the site. This real data was compared with analytical data that have been gotten by modelling the bridge with real dimension in analytical software like ANSYS. It was observed that numerical results are in close agreement with the experimental (real) results.
