Structural health and bridge security in a multihazard environment

Structural Health Monitoring and multihazard considerations are being increasingly considered by the infrastructure owners and administrators for cost-effective evaluation and management. Besides natural hazards, infrastructure security has also become an essential consideration due to threats faced globally by all the infrastructure owners. Structural behavior to natural hazards and progressive deterioration is quite different than when it is subjected to a security related hazard such as blast loading. Thus, the role of Structural Health Monitoring (SHM) under security related hazard is quite different in temporal scale, i.e., its role before, during, and after a security related hazard event. This role is not well understood or studied in the literature. This paper sheds some light on these topics based on expert opinions and these results will be helpful to the infrastructure and security communities in understanding the role of health monitoring and multiple hazards considerations to focus/prioritize their future efforts in this field.
