Damage Localization of Structures Based on Modal Characteristic Changes

Popis výsledku v původním jazyce

In practice, various kinds of damage on reinforced concrete structures can be found. Undetected damage can lead to the failure of structural members or the structure at all. The need for methods for damage detection that can be applied to complex structures led to the development of methods that examine changes in modal characteristics of the structure. Methods and procedures, which use results of an experimental modal analysis for estimation of a degradation degree of a structure, is suitable to verifyon simple structural elements or complex structures, when we know their damage state. This paper presents damage localization of two types of structural elements and one bridge based on modal characteristic changes. For localization of damaged places during experimental and theoretical studies on structural elements the CAMOSUC(j),x, the change of a modal flexibility matrix and especially the curvature of change of a modal flexibility matrix seems to be most appropriate.
