Resum
The paper deals with a methodology for the use of dynamic response as an inspection and surveillance tool for concrete structures (mainly bridges). The method is based upon a finite-element analysis for identification of stiffness characteristics (related to cracking) starting from modal dynamic parameters (natural frequencies and mode shapes) derived from dynamic tests. The use of dynamic data is convenient because acceleration transducers can be easily mounted in the structure instead of displ...
