Abstract
The paper addresses the seismic vulnerability assessment of a multi-span footbridge, prone to span unseating due to shorter seat lengths. The structure is representative of a series of pedestrian crossings located in the Southern part of Portugal, a region with a relevant seismicity. A probabilistic approach allows considering the variability of the seismic action and uncertainties in the definition of the material properties and/or structural behavior. Based on incremental dynamic analyses and corresponding fragility curves, it is shown that, for code compliance design acceleration, there is a significant probability that the structure will only suffer minor damage.
