In recent years there has been constant concern in the scientific community to identify techniques for damage detection in structures. Such apprehension has contributed to the progressive development of Structural Health Monitoring. This paper proposes a methodology using Continuous Wavelet Transform associated with interpolation and regularization techniques applied to the experimental and numerical mode shapes of the Dogna Bridge using only the damaged bridge responses. Dogna Bridge is a four-span, single-lane concrete bridge, 64m long and 4m wide . The results of the analyses are presented and discussed in this paper. K EYWORDS .

I NTRODUCTION n recent years researchers have dedicated considerable attention to the structural safety and reliability of bridges. A substantial number of bridge failures has occurred around the world resulting in economic loss and social consequences. Thus, there is real potential for the application of Structural Health Monitoring (SHM) of bridges to detect and quantify damage. SHM can be used to verify the need for repairs, maintenance, replacement, or even demolition of these structures, thereby protecting the lives of potential users. I
