The University of Padua is conducting a theoretical-experimental research project aimed at evaluating the possibility of using dynamic testing to identify manufacturing defects or structural damage in precast reinforced concrete elements. Experimentally, the research involves the dynamic characterization of a set of hollow panels, 1.20m × 5.80m wide, both undamaged and cracked. As part of this project, two new localization techniques based on damping measurements are proposed: one based on the variation of an energetically equivalent modal damping ratio; and one that consists in distinguishing the contribution of a viscous and friction component in damping, and identifying the damage through friction detection and characterization.
