Structural Health Monitoring (SHM) Innovation or Novelty—The Move to Fleet Level SHM

摘要

Is the time now? When will SHM transition from a novelty to a decision support platform for Bridge Asset Management. Structural Health Monitoring has been used on major bridges and as a research tool for over 50 years. The instances of its application for long term continuous monitoring are in the 100's. During this period the condition of the world's inventory of bridges has steadily declined. Many industry experts are citing the need for better information to manage bridges in a more productive manner. The industry needs to transition to fact based decision making from engineering judgement based on visual inspection. Do those conditions exist now? How will the industry need to adapt to allow for mainstream implementation of measured performance and a timeline for this innovation.
