Abstract

The main non‐residential building types are defined in terms of their use and their vulnerability to ash fall, pyroclastic flow and earthquake. Representative buildings of use classes have been located in the Vesuvius area and geolocated images are provided. Appropriate vulnerability functions for each of the non‐residential building typologies have been identified and descriptions of these and the estimated uncertainty are elaborated upon in the SPeeD robustness study deliverable (Spence, 2009). The final section of this report considers the likely costs associated with building damage following ash fall, pyroclastic flow and earthquake. Mean Damage Ratios (MDR) are provided for each damage class and each hazard, with the potential MDR range described by a Beta distribution; shape parameters are suggested that describe the reliability of the available damage data. For ash fall, the range in costs associated with roof collapse, as a proportion of total building cost, varies significantly between different building types and so MDRs have been suggested for each use class.
