Abstract
This study proposes a probabilistic framework to evaluate building vulnerability under landslide run-out impacts, which integrates dynamic run-out computations and finite element computations. Probability density evolution methods are employed to calculate exceedance probabilities of different limit states. The framework accounts for uncertainties in landslide properties, terrain conditions, and structural characteristics. Results demonstrate that vulnerability depends on landslide intensity, characteristics of elements at risk, and impact mechanisms. Physical characteristics such as velocity, depth, and impact pressure determine damage levels of buildings. The methodology provides a quantitative approach for assessing structural vulnerability in landslide-prone areas.
