FAST vulnerability approach: a simple solution for damage assessment of RC infilled buildings

A straightforward methodology, named FAST , for earthquake damage assessment of infilled reinforced concrete buildings, is carried out using the consolidated framework empl oyed in Performance Based Earthquake Engineering. FAST approach carries out peak ground acceler ation (PGA) capacities calculated from mean inelastic drift capacities of inf illed reinforced concrete (RC) moment resisting frame (MRF) buildings at various damage states. The damage states ar e classified according to EMS 98 scale. FAST covers the range from slight to heavy damage states (DS1 up to DS3), not including very heavy damage and destruction (DS4 and DS5). FAST is a spectral methodology and employs IN2 cu rves. Mean PGA capacities for infilled RC MRF buildings at DS1, DS2, and DS3 can be employed for preliminary prediction of damage. A calibration of FAST is herein provided through the evaluation of root mean square deviations from a set of post-earthquake inspections collected in the area of Pettino, L’Aquila, after the 2009 earthquake
