Abstract

Safety of critical industrial facilities such as Nuclear power plants has gained significant attention against external events in the last decade. Fukushima Daiichi nuclear power station disaster occurred due to flooding of the plant which was caused by the Great East Japan earthquake and the subsequent tsunami. In the US, failure of floodwall system during hurricane Katrina caused widespread damage. Floodwalls are essential to mitigate the effects of rising sea-levels due to climate change. Critical industrial facilities are being increasingly protected from the effects of floods through the use of flood protection systems such as floodwalls, dams, and weirs. This paper evaluates the fragilities for failure of a concrete floodwall due to various failure modes under a multi-hazard scenario (flooding and seismic events). Structural failure of the concrete floodwall is characterized by excessive deformation failure mode for seismic loads. The failure modes considered for flooding loads are rigid body failure and foundation failure.
