ELASTİK ÖTESİ SPEKTRUM KULLANILARAK YAPILARIN DOĞRUSAL OLMAYAN ANALİZİ

Abstract

Yapıların doğrusal dinamik analizinde daha karmaşık yöntemler yerine spektral analiz yöntemi kullanılmaktadır. Elastik analiz ile ilgili çalışmalar, spektral analiz ile elde edilen sonuçların, zaman tanım alanında analize ait olanlara yakın olduğunu göstermiştir. İşletme yükleri altında yapı elastik davranış sergilerken, deprem etkisi durumunda elastik ötesi analiz gerekli olmaktadır. Bu çalışmada elastik ötesi analiz için literatürde önerilmiş olan bir yöntem açıklanmıştır. Sunulan yöntemde elastik ötesi spektrum kullanılmaktadır. Çalışmanın sonunda yöntemin değerlendirmesi için bir örnek incelenmiştir.

NONLINEAR ANALYSIS OF THE STRUCTURES USING INELASTIC SPECTRUM

Abstract

Spectral analysis method is used for the linear dynamic analysis of the structures instead of the more complicated methods. Studies that are concerned with elastic analysis, presented that the results obtained by the spectral analysis method are closer to the ones belong to the time history analysis. When subjected to the service loads, structures respond in an elastic manner, but when subjected to earthquake loads inelastic analysis is needed. In this study, a method proposed for the inelastic analysis in the literature is explained. Inelastic spectrum is used in the presented method. For the assessment of the method, an example is investigated at the end of the study.
