investigating the effect of changing performance objective on resilient structures

With the development of earthquake engineering science and the experiences gained from the previously occurred earthquakes and also the compilation of seismic and design codes, the concept of safe structures that are resistant againstearthquakes has been partly determined. the codes have defined seismic demands and certain performance levels based on defined performance objectives. however, according to what was observed in recent earthquakes, the structures have not been able to show the expected performance during strong earthquakes (un et al., 2015; molina hutt et al., 2015).this leads to numerous problems and financial damages and restoring to the pre-earthquake state would be timeconsuming and costly (han et al., 2016). therefore by changing the performance objectives of the structures we might be able to design them in a way that they would be more resistant against earthquakes and bear less damage. this would alsomean less structure repair time and cost and it would minimize the mental and physical injuries of the afflicted and would increase the general resilience of the buildings. in this study, concrete frames are designed under design basic earthquake (dbe) and maximum considered earthquake (mce) spectral response acceleration. then, according to the methodology of the research, the amount of losses caused by the earthquake is evaluated based on the fema p-58method by the pact software.
