Damage localization and quanti cation in simply supported beams using static test data

A novel simple method using static test data for damage detection, localization, and quanti cation in beams is presented in this paper. The method is based on the change of the de ections of the beam between a reference and a damaged state. For simply supported beams with a single damage, the maximu...
