Ambient Vibration Monitoring
Chapter One
Introduction
The increasing number of civil engineering structures in the field of traffic
infrastructure entails the increasing significance of maintenance problems of
such engineering structures. Bridges are monitored by periodic supervision
measures with the aim of minimizing the safety risk for the user, on the one
hand, and of keeping the costs for the maintenance as low as possible by the
execution of rehabilitation measures at the right time, on the other hand.
Potential Impact
Civil engineers concerned with supervision of structures for safety and maintenance
reasons are aware of the limitations of their current practice of condition
assessment based on visual inspections. Typical routine applications of
condition assessment are carried out on structures applying rating systems. The
consequence would be unbearable costs on society for replacement and retrofit
tightened up by shrinking budgets. The expressed intention of the bridge owners
globally is to reduce the number of bridges rated deficient by 30% within a short
time through the appl ... read full excerpt from Ambient Vibration Monitoring ebook
