RockDamage

RockDamage is an Excel tool that calculates the fragility curves of a masonry wall that is impacted by rock blocks. The fragility curves express the probability of exceeding a given level of damage for a building (e.g. slight, moderate and high, depending on its extent on the wall surface), for increasing magnitude/intensities of an external action. The probabilistic assessment of the performance of a masonry wall includes two types of uncertainties that are (i) inherent to the masonry typology: wall width and tensile resistance and (ii) inherent to the impact rock block properties: velocity and volume.
