| Description
| - U reálných betonových konstrukcí se projevuje mnoho typů poškození. Poškození, které nebylo včas zjištěno, může vést až k selhání konstrukce. Potřeba metod, které by mohly být využity na konstrukci jako celku, vedla k vývoji metod detekce poškození založených na změně modálních charakteristik. Metody a postupy, které využívají výsledky modální analýzy pro zjištění úrovně degradace konstrukce, je vhodné ověřovat na jednoduchých stavebních prvcích nebo na celých konstrukcích, kde známe aktuální stav poškození. V článku je prezentována lokalizace poškození dvou typů konstrukčních prvků a jednoho mostu na základě změn modálních charakteristik. Pro detekci míst s poškozením byl využit zejména koeficient CAMOSUC, změna matice modální poddajnosti a druhá derivace změny diagonálních členů matice modální poddajnosti. (cs)
- 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 verify on 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.
