Abstract

A generalized formulation of the FAST vulnerability method for Reinforced Concrete Moment Resisting Frame (RC-MRF) buildings with irregular distribution of infills in elevation is presented. This method, which belongs to the wider family of spectral-based methodologies for the simplified assessment of infilled RC MRF buildings, has been already proposed for uniformly infilled frames and applied in the case of post-earthquake damage survey results for benchmarking purposes. The generalized approach allows to consider a reduction of the amount of infills at the ground floor. Thus, this new form of FAST is capable of computing all intermediate situations between the uniformly infilled and pilotis (no infills at ground storey) cases. Finally, the approach provided is applied to the case of Lorca (Spain) 2011 earthquake damage survey data.
