Abstract

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. Düzce 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.

Özet

Bu araştırmada, zemin yapısı etkileşimli ve etkileşimsiz, 2 boyutlu çok katlı çelik çerçeveler için doğrusal ve doğrusal olmayan zaman adım analizi yapılmıştır. Çerçeveler 3 kattan 20 katına kadar farklı yüksekliklere sahiptir. Zemin ve tekil temel sistemi doğrusal yaylar ve sönümleyici ile modellemek için alt yapı analiz metodu kullanılmıştır. Ayrıca tepki-spektrum analizi yapılmıştır. Düzce deprem ivme kaydı seçilerek spesifik tepki spektrumuna ölçeklendirildi PGA 0.35 ve Euro code 8'e göre zemin tipi B (katı) seçildi. Temel periyot ve zemin kesmesi, zemin-yapı etkileşimi dahil edilerek ve edilmeyerek araştırılmış ve sonuçlar karşılaştırılmıştır.
