Seismic Vulnerability of Old Italian Railway Stations
Abstract Most of Italian railway stations date back to the second half of the 19th century, when the railway network was created. Although originally belonging to different companies and in spite of some modifications occurred over the years, most of these stations are masonry buildings conceived according to similar standards, with typical dimensions and morphology mostly depending on the expected traffic of passengers and goods. The common structural features of these buildings allow grouping them into building typologies, characterized by a similar structural response. This is relevant for the assessment of the seismic vulnerability of these structures, whose damage or collapse could lead to critical consequences, due to the potentially high number of victims and to the risk of interruption of critical lines. Nonlinear global analyses by equivalent-frame macroelement modelling and linear kinematic analyses of possible local failure modes have been used to assess the seismic response of building prototypes representative of the most common architectural typologies. A logic tree approach was used to consider uncertainties in mechanical properties, geometry and construction details for the derivation of fragility curves for different limit states.
