Abstract

Seismic behaviour of Special Reinforced Concrete Frame with high ductility, designed according to the 4th edition of Iranian earthquake standard 2800, in four structural models of 4, 8, 12, and 24 stories under all of earthquake records of the far-field and near-field recommended by FEMA-P695, have been evaluated by performing incremental dynamic analysis (IDA). Fragility curves are drawn for structural models. The results of this research and the evaluation of effective parameters in the evaluation of the safety margin of collapse show that the special reinforced concrete frame (SRCF) designed with the 4th edition of the 2800 standard, except for high-rise structures, has an acceptable performance against the design seismic loads and maximum credible earthquake.
