Regarding the seismic hazard potential of Iran region and the damage exerted on the buildings during previous earthquakes, the developments of seismic engineering and vulnerability of buildings should be further taken into account. Due to the increasing use of reinforced concrete buildings in Iran, three 6.12.18 stories concrete flexural frames with shear wall system were selected and after designing based on 9th capture of Iranian national codes and the 2800 standard code were simulated via IDARC software with the capability of nonlinear dynamic analysis. After choosing the reliable accelographs adjustment with Iran tectonic conditions the damage estimates of these structures were investigated through performing nonlinear dynamic analysis. Note that the Ang-Park damage index was used as a reliable criteria for investigation of seismic response of reinforced concrete systems.
