In developed countries, sustainable economic growth and social development are intimately linked to the reliability and durability of civil structures such as buildings, bridges, and dams. The intended service lives of civil structures are typically decades or even centuries. During this time, civil structures are possibly exposed to abnormal loads of different types, ranging from natural hazards (such as earthquakes, floods, and hurricanes) to human-made disasters (such as terrorist attacks, fires, or vehicular collisions). At the same time, structural safety and condition undergo gradual deterioration because of material aging, harsh environmental conditions, and increasing loads. This long-term deterioration may not only impair the functionality of civil structures but also undermine their capacity against future extreme loads. The associated social, economic, and political consequences can be enormous and may exert serious, widespread, and prolonged adverse impacts on various societal sectors.
