The Comparison of Seismic and Structural Parameters in Steel Structures for Different Spectra

Abstract

In order to determine the earthquake performance of the buildings, the interactions of many different parameters were considered. These parameters generally include data on the seismicity of the region, local soil conditions, and structural characteristics. In this study, the seismicity factor has been selected as the variable. An eight-storey steel structure with the same local soil and structural characteristics was selected as a sample. Turkey has seven different geographical regions. So, one sample province from every seven different geographical regions of Turkey was taken into consideration which was earthquake hazard is variable. Static adaptive pushover analyzes were performed for the selected steel structure by using special design spectra obtained for each province because this analysis is allowing the use of these spectra. In this study, first of all, the changes in earthquake parameters that will be used to determine the earthquake effects on structures are examined. The results of structural analysis using special design spectra obtained for each province were also examined. This study aims to determine the effect of seismicity risk on both earthquake and structural outcome parameters for steel structures. The design spectra significantly affect the demand displacement of buildings. Therefore, damage estimates and building performance will better reflect real values for the buildings which did not meet the demand displacement.
