Experimental damage detection using observability grammian matrix
Experimental damage detection using observability grammian matrix
Structural Health Monitoring (SHM) has diverse potential applications, and many groups work in the development
of tools and techniques for monitoring structural performance. These systems use arrays of sensors
and can be integrated with remote or local computers. There are several different approaches that can be
used to obtain information about the existence, location and extension of faults by non destructive tests. In
this paper an experimental technique is proposed for damage location based on an observability grammian
matrix. The dynamic properties of the structure are identified through experimental data using the eigensystem
realization algorithm (ERA). Experimental tests were carried out in a structure through varying the mass
of some elements. Output signals were obtained using accelerometers.

Abstract
Structural Health Monitoring (SHM) has diverse potential applications, and many groups work in the development
of tools and techniques for monitoring structural performance. These systems use arrays of sensors
and can be integrated with remote or local computers. There are several different approaches that can be
used to obtain information about the existence, location and extension of faults by non destructive tests. In
this paper an experimental technique is proposed for damage location based on an observability grammian
matrix. The dynamic properties of the structure are identified through experimental data using the eigensystem
realization algorithm (ERA). Experimental tests were carried out in a structure through varying the mass
of some elements. Output signals were obtained using accelerometers.
