Abstract

Analysis Methods for the Investigation of the Seismic Response of Concrete Dams The consideration of the dam-foundation-reservoir interaction is extremely important for estimating the seismic response of concrete gravity dams. Moreover, nonlinear analysis may be required for determining the possible risk associated with dams. In order to address these issues, DSI recently published the “Guidelines for Seismic Design of Concrete Dams”. Authors who have contributed to the preparation of this document provide a perspective on the seismic safety/design of concrete dams and structural analysis methods along with a set of illustrative solutions. The study presented herein provides important results on the necessity of conducting two and three dimensional seismic analysis, the use of nonlinear analyses techniques and the important factors that affect the seismic response of the concrete gravity dams

Beton Barajların Deprem Davranışlarının İncelenmesinde Kullanılan Analiz Metotları

Abstract

Barajların deprem davranışlarının belirlenmesinde baraj, zemin ve rezervuar etkileşiminin dikkate alınması oldukça önemlidir. Ayrıca olası risklerinin belirlenmesi için doğrusal olmayan analizlerin de gerçekleştirilmesi gerekebilmektedir. Bu amaçla Devlet Su İşleri Müdürlüğü önderliğinde "Beton Barajların Tasarım İlkeleri" hazırlanmıştır. Bu rehberin hazırlanmasına katkıda bulunan yazarlar, beton baraj sismik tasarımı hususunda literatür değerlendirmelerini, yapısal analiz araçlarını, baraj sismik güvenliğine ilişkin görüşlerini ve örnek çözümlemelerini sunmaktadır. Çalışma iki ve üç boyutlu analizlerin gerekliliği, doğrusal olmayan analizlerin uygulama şekli ve baraj deprem davranışını etkileyen önemli faktörler konusunda önemli sonuçlar ortaya koymaktadır
