Seismic Risk and Finite Element Modelling Influence of an Existing One-Storey Precast Industrial Building

Precast structures are widely used in Southern Europe particularly for indus- trial buildings. Most of such buildings have been built before the enforce- ment of modern anti-seismic regulations showing a poor performance during past major earthquakes. Focusing on existing one-storey precast industrial buildings, the paper investigates the influence of modelling choices on the risk assessment, direct losses, and required structure retrofit time. RC forks, cladding panels, and elements connections were specifically considered. A precast industrial building with structural details compatible with 1980s Italian regulations was selected and analysed. In general, the failure was associated with the collapse of roof elements.
