讲座内容简介：Maintenance and management of ageing transportation infrastructure systems have become a great challenge for engineers worldwide. However, the existence of subjective and inaccurate condition assessment is the most critical technical barrier to effective and efficient infrastructure management. For existing transportation structures which have experienced progressive deterioration and/or severe loading events due to environmental effects, there is a need for a health prognosis to confidently predict how they will respond to future loading and when they will fail to deliver the required capacity. The structural health monitoring strategy and reliability-based performance assessment techniques have tremendous potential for structural safety and/or economic benefits. In this seminar, new damage diagnosis and prognosis methods will be discussed with several case studies. A structural health mentoring strategy, together with new developed artificial intelligence techniques, will then be presented to monitor the current state, predict the future performance, optimize the maintenance schemes, and intellectualize the system operations for deteriorating structures during the service life.
