Analytical tsunami fragility curves for seaport RC buildings and steel light frame warehouses

摘要: Abstract Harbours are crucial assets for the sustainment and development of human activities. The recent devastating tsunami events as well increasing number people, structures economic activities being exposed to hazards revealed need estimation effects wave on seaport structures. However, only a limited tools estimate potential impacts available until now. This study aims at developing analytical fragility functions some representative typologies in Greece. In particular, low-code moment resisting frame (MRF) dual reinforced concrete (RC) buildings various heights, typical warehouse considered analysis. A numerical investigation is performed considering different combinations loads based FEMA P646 (2008) [1] recommendations gradually inundation depths structure typologies. To minimize uncertainties related definition damage limit states, nonlinear static analyses appropriate capacity curves derived Structural states defined terms threshold values material strain. For complete state, shear failure also considered, since collapse may be caused by occurrence either flexural or structural components. Fragility numerically calculated using regression They could used within probabilistic risk assessment framework assess vulnerability RC warehouses hazard along European-Mediterranean other regions similar facilities worldwide.
