Uncertainty in damage assessment of structures and its numerical simulation

Supporting structures are subject to damage processes during their service lifetime. Damage may occur in the form of material or structural damage dur ing the loading process. The parameters for describing damage are modeled a s fuzzy values in the computational model. Damage is modeled by means of a fuzzy damage indicator, which assesses changes in stiff-ness as a result of damage. The damage indicator is applied for assessing damage development i n plane reinforced concrete framework structures, Damage assessment with th e aid of the introduced fizzy damage indicator is demonstrated by way of tw o examples.
