چکیده مقاله:

Different methods are used to estimate the location and intensity of damage in structures and these methods use different staticand dynamic responses. Even though many methods have been proposed for damage detection in the last two decades, sensitivitybasedanalyses are still popular. In this research, the effects of different responses in sensitivity-based methods, for two cases ofadditive and multiplicative noises in a truss and a two layers dramatic dome are studied. First, by imposing noise in variousresponses and implementing Monte Carlo sampling, an index was devised to evaluate the sensitivity of each response to sensorlocation. Then, different responses are used to detect damage in structures, but since it is an ill-posed problem, Tikhonovregularization scheme is used to evaluate exact results of each response, through an updating problem. By comparing the results, itis concluded that sensitivity of static responses to sensors location is less and static response is the most effective response withfewer errors in damage detection of the cases.
