Experimental Modal Test of Civil Concrete Bridges
Concrete bridges are one of the most important civil infrastructures in the new metropolises. Experimental vibration measurement is one of the most widely used approaches for tension and damage analysis of these concrete bridges. The key to success of this technique is the accuracy of identified fundamental frequency of each bridge. In this paper experimental modal analysis of concrete bridges is carried out using output only acceleration records of a concrete bridge. A data analysis approach to determine fundamental frequency is used for case study of Chamran bridge in Isfahan city where the test carried out using ambient vibration measurement showed high identification accuracy and confidence of this method. As the bridge is one of the most important connecting links in the city, and while its building quality was always remained controversial, the output information of this test will be highly valuable for city authority figures to decide for retrofitting or even rebuilding the bridge.
