and robust approaches for detecting and identifying damage in civil and mechanical engineering
systems. A salient characteristic of a well...
Early damage detection in structural health monitoring by a sensitivity method and DBSCAN clustering
Early damage detection is an important and initial step in structural health monitoring (SHM)
that aims to evaluate the global state of a structure and finds whether damage is available
throughout the structure. To do this, a new...
Comparative study on flexibility based methods for damage diagnosis of bridge structures
This paper presents a comparative study to identify damage in bridge structures based on the modal flexibility matrices. In the study, the classical Pandey and Biswas method and the Ritz vectors extracted from flexibility ...
