| Zusammenfassung |
| Plinian and subplinian volcanic eruptions can be accompanied by tephra falls
which may last hours or days, posing threats to people, buildings and
economic activity. Numerous historical examples exist of tephra damage and
tephra casualties. The mechanisms and consequences of roof collapse from
static tephra load are an important area of tephra damage requiring more
research.
This paper contributes to this work by estimating the structural
vulnerability of buildings to tephra load based on both analytical studies
and observed damage. New studies are presented of roof strengths in the area
around Mt. Vesuvius in southern Italy and of field surveys undertaken in
other European volcanic locations to assess building vulnerability to tephra
fall.
The results are a proposed set of new European tephra fall roof
vulnerability curves in areas potentially threatened by explosive volcanic
eruptions along with comments on the human casualty implications of roof
collapse under tephra loading. Some mitigation recommendations are provided. |
