Challenges in Structural Health Monitoring 22 Us-japan Bridge Engineering Workshop Seattle, Washington

چکیده
Structural health monitoring through field instrumentation has been carried out successfully on many highway bridges to monitor the short-term and long-term performance of structures. Properly designed and strategically placed instruments can help collect valuable data regarding the condition, the stress and strain, deflection, temperature gradients, and the time-dependent properties, such as creep and shrinkage in a structure. The data may be used to verify the design assumptions, to make modifications, to improve on future designs, to assess the general health of bridges, and to provide valuable information for a bridge management system for making decisions regarding preservation decisions. The challenges in structural health monitoring are in finding cost-effective and reliable sensors to remotely and continuously monitor the conditions of major bridges.
