A generalized formulation of FAST vulnerability method for Reinforced Concrete Moment Resisting Frame (RC-MRF) buildings with non-uniform distribution of masonry infills in elevation is presented.This method belongs to the wider family of spectral-based methodologies.It was already proposed for uniformly infilled frames, and then applied to different earthquakes for benchmarking purposes.The new generalized approach allows us to consider a reduction of the amount of infills at the ground floor.Thus, this new version of FAST is capable of computing all intermediate situations between the opposite cases: uniformly infilled and pilotis (no infills at ground storey) MRF.Finally, this generalized FAST method is applied to the case of the Lorca (Spain) 2011 earthquake, using parameters according to the local construction practice of the area.Results show a fair agreement with damage survey data.
