%0 Journal Article %T Soil Structure Interaction Analysis of Two Dimensional Steel Frames under Seismic Loads %A Cemile £¿z£¿am %A Mustafa £¿zak£¿a %J - %D 2018 %X In this research work, a linear and nonlinear time history analysis for 2D multi-story steel frames on gravel soil with and without soil structure interactions have been done. Frames have different height start from 3 stories and up to 20 stories. A substructure method is used to model soil and shallow (footing) foundation system by linear springs and dashpots. The response spectrum analysis has also been done. D¨¹zce earthquake accelerograms records are selected and scaled to specific response spectrum with PGA 0.35 and soil type B according to Eurocode 8 is considered. Fundamental period and base shears have been investigated with and without soil-structure interactions; the results have been presented and compared %K £¿elik £¿er£¿eve %K zemin yap£¿ etkile£¿imi %K tepki sepktrum analizi %K zaman ad£¿m analizi %K sismik y¨¹k %K temel periyot %U http://dergipark.org.tr/humder/issue/42425/492907
