Cultural tourism is one of the priority sectors by which the Government of the Philippines aims to foster inclusive and sustainable socio-economic development, due to its potential for job creation. Filipino cultural heritage (CH) assets are particularly vulnerable to natural hazards (e.g., earthquake ground shaking, strong wind, and flooding) due to their age and type of construction. In particular, non-engineered CH roofs have been recognized as the most vulnerable component in the building envelope due to typhooninduced wind uplift. Consequently, they may cause large amount of economic loss and disruption to CH assets. This paper introduces a simulation-based approach for non-engineered CH roof fragility derivation, i.e., to assess the probability of different levels of damage experienced by CH roofs over a range of wind hazard intensities. In this approach, two limit states are considered, corresponding to roof-panel pullout and pullover failure modes. An illustrative application of the proposed procedure is finally presented with reference to 17 priority CH buildings across the Philippines.
