Fragility Assessment of Vinyl Greenhouses and Livestock Sheds Subjected to Volcanic Ash Fall Hazards

摘要: In this study, fragility functions are developed to estimate expected volcanic ash damage vinyl greenhouses and livestock sheds among common agricultural facilities in South Korea. The derived through the FOSM (first-order second-moment) analytical approach based on thickness distribution of observed 1980 eruption Mt. Saint Helens USA facility codes specifications evaluated represent conditional probability failure over full range loads. For evaluation, 4 types (i.e., automated, single span, tree crop, double span types) multi-hazard resisting 3 standard, coastal, mountain conventionally utilized Korea considered. All estimated study fitted using parameters...
