Quantifying Deterioration or Damage Levels with Novel Bridge Monitoring Concepts
This paper reviews current structural health monitoring (SHM) technologies against bridge design and operation characteristics, and proposes a transformative concept of structural behavior monitoring (SBM). The SBM concept is focused on abnormal condition alerting, damage quantification, and detection of various design limit states such as bridge scour, steel corrosion, yielding and buckling, and cracking. For a cost-effective management of bridge networks, the SBM concept is realized in a hybrid computational/ instrumented simulation framework of bridges, using adaptive multi-scale bridge modeling. This advance potentially provides a maintenance prioritization framework of the U.S. aging bridge network with associated assessment tools for various limit states. The proposed concept can change engineers' perception from the less favorable SHM to the more receptive SBM strategy. Emphasis in this paper is placed on SBM's attributes, performances, and potential impact on structural safety and functionality.
