Structural Health Monitoring & Condition Assessment of Chulintna River Bridge

The objective of the proposed research is to improve the safety of bridge structures in the state of Alaska through implementation of innovative structural health monitoring (SHM) technologies to evaluate the structural integrity and serviceability, and to provide reliable information for changing structural response, decision-making of maintenance/repair and closure, etc. of monitored bridges. Based on a synthesis of current-in-use and emerging SHM knowledge and technologies with a specific interest in what could be potentially used on bridges in cold, remote regions, such as Alaska, this research is to establish a bridge SHM program for the Alaska Department of Transportation and Public Facilities (AK DOT&PF). This objective is going to be achieved by identifying appropriate technologies, developing technologies where items are needed but missing, and implementing these technologies to remotely monitor and on-site evaluate the structurally deficient Chulitna River Bridge. A SHM protocol will be developed for applications to bridges in the State of Alaska. A SHM system with a variety of sensors will be developed to measure and monitor structural and environmental conditions to assist in evaluation of the Chulitna River Bridge performance. This system will be designed to detect bridge structural defects or deterioration in its early stages and to assist in the prediction of its future performance. It will also be utilized to mitigate impacts resulting from changed conditions. It is expected that this system will be able to provide more reliable information on the real structural health condition. We expect that it can be used to improve safe performance of this bridge. As a new safety and management tool, monitoring will complement traditional bridge inspection methods. Implementation of an effective monitoring system will likely result in a reduction in inspection manpower, early detection of deterioration/damage, development of optimum inspection and repair schedules before the deterioration/damage grows to a condition where major repairs are required and as a result this technology can used to reduce life cycle costs.
