Abstract

Iran is located on an active tectonic zone between Asian and Sweden Arabic Plates Which has experienced large ground motions. Manjil 1990 and Bam 2003 earthquakes that have devastated a large part of Iran have caused several changes in Iranian Code of practice for seismic resistant design of buildings Code2800 . This paper evaluates concrete frame buildings are designed based on equivalent static code2800 that are widely use in practice, with Nonlinear static pushover analysis (NSPA) based on FEMA356, ATC40 and FEMA440. To achieve this objective a set of 5, 7 and 10 stories concrete frame building with different importance factors and different concrete compression strength, first based on equivalent static Code2800 have been analyzed and designed and then NSPA have been performed. According to the results of the analysis it can be concluded that the performance level of intermediate importance buildings, like residential and commercial ones analyzed and designated with code2800, is between life safety and collapse prevision. The performance level for very high importance buildings, like hospitals, is about Immediate occupancy and with increasing concrete compression strength, performance point shifts toward linear part of capacity curve that are acceptable with code2800 objectives.
