Assessing building reparability after damaging earthquakes with a sustainable performance based approach

Building reparability after an earthquake is a cent ral issue for a sustainable engineering. Effective policies concerning building reparability should account for building Initial Performance (IP) before an earthq uake and of Performance Loss (PL) due to seismic damage, proper ly accounting of repair/strengthening costs. This p aper presents a pushover based procedure for evaluating IP and PL and demonstrates its usability by means o f a case study for an RC building. Moreover, preliminary estimatio n of damage-dependent reparation costs for the case study building shows the possibility of associating PL th resholds to reparability limit states.
