Damage Detection by Dynamic Analysis of Steel Bridges
Dynamic analysis and full-scale experiments of existing bridges; system identification and damage detection exploring sensor technology and modal analysis.
Many bridge structures today are approaching or have exceeded their initial design life. These structures are used despite aging and the associated damage accumulation. Being able to detect damage at the earliest possible time and monitor the health of bridge structures is becoming increasingly important. This is motivated by significant economic and life-safety benefits.
It is often limited information about the existence, location, type or extent of the damage in bridges. Hence, performing inspections to detect damage is a challenging task. Being able to 1) further develop bridge inspection methods by using structural monitoring and 2) move towards a condition-based maintenance philosophy where a sensing system on the structure monitors the system and notifies if damage is detected, is important. Ultimately, the goal is to ensure safe use, prevent failure and control further degradation of existing bridges.
Objectives
The overall research objective is to develop methods for damage detection of bridge structures by dynamic analysis and full-scale experiments. This includes methods by system identification and operational modal analysis using different sensor technology to improve bridge inspection. The research is divided in the following objectives:
- Study Structural Health Monitoring (SHM) with emphasis on damage detection algorithms.
- Develop general methods and tools for designing SHM systems including analysis and evaluation of data obtained from measurements with respect to damage detection for short and long-term SHM.
- Validate the developed methods through case studies.
