Analytical techniques for damage detection and localization for assessing and monitoring civil infrastructures

D. Bernal,    Northeastern University, USA

Abstract:

The chapter contains a review of some aspects of structural dynamics and includes a section on damage detection and damage localization from vibration signals. Novelty detection is treated in detail, with special attention given to the situation where the environmental variables are not measured. Two techniques that can detect damage without the need for repeated identifications are presented (one based on a subspace approach and one on the Kalman filter) and a discussion of change detection using a cumulative sum chart from process control is included. The techniques presented are ...
