FAST simplified approach for seismic assessment of infilled RC MRF buildings: application to the 2011 Lorca earthquake

Abstract

Comunicación oral presentada en el Congreso ERES 2013: 9th World Conference on Earthquake Resistant Engineering Structures: Resultados de la investigación realizada en el campo de la ingeniería estructural sísmica que consiste en la elaboración de un método propio que permite evaluar la vulnerabilidad sísmica a gran escala y que es capaz de predecir los daños esperados cuando los edificios con estructura de hormigón armado y con tabiquería de fábrica se ven sometidos a un evento sísmico. El método ha sido validado contrastando sus predicciones con los daños producidos por el terremoto del año 2011 en los edificios construidos con dicha tipología estructural en la ciudad de Lorca.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.Gómez Martínez, F.; Perez Garcia, A.; Verderame, G.; De Luca, F. (2013).
