Mega-structure Diagnostic & Prognostic System

Mega-structures such as long-span bridges and high-rise structures are vital civil infrastructure. Maintaining their safe and reliable operation is critical to secure the well being of people, to protect the vast investments, and to support the vitality of economy. However, mega-structures cannot last forever; they even begin to deteriorate once they are built. Therefore, it is of paramount importance to diagnose and prognose the safety of mega-structures throughout their whole life-cycle.

PolyU has devised a comprehensive diagnostic and prognostic system to provide a life-cycle screening for mega-structure’s safety. Not only can it identify the structural damage at the earliest possible stage to avoid any catastrophic structural failure, but also can assess structural health immediately after any major hazardous event; Not only does it inform us what/where the severest damage is and when/ how rehabilitation should be processed, but also tells us whether immediate evacuation of the occupants/contents is necessary.
