Abstract: Most of diagnostic techniques used within the class of beam‐like structures are based on the requirement that the damage location closely matches with the calculated and the observed frequency changes. Since these variations ...

Abstract: Nondestructive dynamic methods are a useful tool in structural engineering. Their purpose is twofold. First, they provide guidance on the validation of a mathematical model of the structure under investigation. Second, ...

Abstract: Structural identification via modal analysis in structural mechanics is gaining popularity in recent years, despite conceptual difficulties connected with its use. This paper is devoted to illustrating the advantages and ...

Abstract: This paper deals with a dynamic method for damage detection in beams. Under the assumption that the damaged beam is a perturbation of the undamaged one, it is shown that natural frequency and antiresonant frequency shifts ...

Abstract: This paper continues a line of research aimed at the development of a dynamically based health condition monitoring of bridge structures in the area of Friuli Venezia Giulia, Italy. One subject of this research program has ...

Abstract: The Hypo Bank headquarters complex, a structure formed by two adjacent seven-story buildings, was subjected to a series of harmonic forced vibration tests in August 2005. In Part I of this research, the natural frequencies, ...

Abstract: This paper concerns with the identification of multiple open cracks in a beam by measurements of the damage-induced variations in the static deflection of the beam under a prescribed load condition. Each crack is simulated ...
