Resilience monitoring of bridge networks
Abstract »Recent natural and manmade disasters illustrated the importance of building infrastructure that not only can withstand abnormal hazards but also can easily return to adequate functionality when subjected to unforeseen service interruptions. Infrastructure resiliency is a measure that accounts for adequate structural capacity to withstand abnormal hazards (network robustness) and adequate response and recovery time during and after such abnormal events (resourcefulness and recovery) to describe infrastructure functionality/performance. It can be categorized into two types: asset resilience and community or network resilience. A network is generally composed of several single assets. Moreover, it has been argued that proper infrastructure resilience (both asset and community/network) should accommodate following five components in an integral manner: assessment, acceptance, treatment, monitoring, and communications. This paper deals with resilience monitoring of bridge networks but can be generalized to all infrastructure related assets. Adequate performance of a bridge network is dependent not only on performance of bridges in the network but also on adequate performance of other infrastructure asset types within the network. These include assets -- such as roadways, tunnels, sign structures, culverts, and power lines -- that are part of the network. As such, the inclusion of these assets within the bridge network is essential for accurate and meaningful resilience monitoring efforts. Monitoring bridge network resilience has to cover all the above aspects of the network with progression of time (or “time march”). Close monitoring of robustness, resourcefulness and recovery, redundancy and physical links between the pertinent network assets and other relevant issues in an integrated and optimal fashion is essential. This work will explore different resilience monitoring techniques that are available to bridge network managers. These techniques include, but not limited to, structural health monitoring (SHM) and nondestructive testing techniques (NDT).
