Infrastructure
Monitoring of civil infrastructure such as bridges and buildings is critical to the long-term
operational cost and safety of aging structures. Knowledge of a structure's health, load bearing
capacity, and predictive remaining life are the essential elements of the broad market term,
Structural Health Monitoring (SHM). Bridges have become a high profile target for SHM solutions
because they constitute the most vulnerable element of the transportation infrastructure. In
recent publications the U.S. Federal Highway Administration (FHWA) has reported that nearly
30 percent of the country's 590,000 bridges are structurally deficient or functionally obsolete,
in terms of dimensions, load or other characteristics. In addition, many of these bridges are
small and medium span structures and are in rural locations. The FHWA claims that two main reasons
for the deterioration of the infrastructure are aging combined with the significant increase
in traffic levels. This is resulting in growing liabilities from wear and tear on many bridges
beyond the levels that they were designed to handle.
AlphaSTAR's physics based virtual simulation capabilities represent significant applicability
to many of the core challenges facing structural health monitoring. Using AlphaSTAR's definition,
SHM includes monitoring, diagnosis, prognostication, repair, and inspection. For over five
years, AlphaSTAR has teamed with academic, government, and industry leaders to pioneer an SHM
solution. The first utilization of the solution was a combined effort with the University of
California (UCI) when the US Army awarded a multi-year contract to expand and upgrade their
web based hardware-software online Diagnostic Prognostic System (DPS) and Real Time Intelligent
Field Repair for structural evaluation of the Composite Army Bridge (CAB). The SHM research
for the CAB has since evolved into a complete offering now commercially available from AlphaSTAR
including an industry leading wireless sensor network solution.
