Seismic Fragility of Aging Offshore Platforms
Aging infrastructure; Fragility analysis; Offshore structures; Probabilistic assessment; Seismic risk
The importance of infrastructure to both the fabric of society and its economy is becoming increasingly more apparent. The robustness of infrastructure systems can be judged by their capacity to accommodate change over time. However, the rapid rate at which our infrastructure is aging requires new solutions for providing a resilient infrastructure that can last for future generations.
Earthquakes are paramount among the natural hazards impacting the infrastructure. The past several decades have witnessed a series of costly and damaging earthquakes. The events would have even more devastating effects if a major earthquake were to hit an old and unprepared infrastructure. The challenge that engineers today face is not only on how to construct new infrastructure with proper resistance to earthquakes but rather to update older structures that do not have the proper...
