Abstract

In this paper, a 15-story steel building was designed based on Iranian code No. 2800 in order to study the effects of rocking systems on the seismic response of high-rise steel buildings. The selected accelerograms were related to the Chi Chi, Landers, Loma Prieta, Northridge, Parkfield, San Fernando and Tabas earthquakes which were selected and scaled according to Iranian Standard No. 2800. These accelerograms were related to the stations which were registered at the distance of 20 to 60 kilometers from the fault and did not have the near-fault earthquakes characteristics such as forward directivity and fling step and etc. Furthermore, the magnitude of all the selected earthquakes was between 6. 5 and 7. 5 Richter. Then, nonlinear time history analysis was used to investigate and compare the seismic response of the studied building in cases with and without using the rocking system. The results of studies (including base shear, drift, displacement of roof, acceleration of roof and etc. ) indicated that using roc king system in the high-rise steel buildings could cause significantly reduce the seismic response of high-rise steel buildings.
