Approach to reduce the limitations of modal identification in damage detection using limited field data for nondestructive structural health monitoring of a cable-stayed concrete bridge

The objective of the study was to propose a technique to reduce the limitations of modal identification in damage detection using reduced field data for nondestructive structural health monitoring of a cable-stayed concrete bridge. Simply supported bridge models were constructed with predetermined d...
