A Study Depending on the Probabilistic Seismic Hazard Analyses for Design Spectrum Parameters

Abstract

Within the scope of this study, design spectrum parameters (constant acceleration region corner periods and site factors) are proposed, depending on probabilistic seismic hazard analyses conducted in a region located in a part of the North Anatolian Fault Zone. The outcomes are obtained for different site conditions and return periods. Two different seismic source models which are areal source, and fault and gridded seismic source models are used for probabilistic seismic hazard analyses. The ground-motion characterization is handled by selecting the ground-motion prediction equations that reflect well the seismic excitations around the study region. The computation of constant acceleration region corner periods and site factors are based on the empirical relationships that depend on the PGA or spectral accelerations at T = 0.2 s and 1.0 s for rock sites.

Tasarım Spektrumu Parametreleri için Olasılıksal Sismik Tehlike Analizlerine Bağlı Bir Çalışma

Abstract

Bu çalışma kapsamında tasarım spektrumu parametreleri (sabit ivme bölgesi köşe periyotları ve zemin faktörleri) Kuzey Anadolu Fay Hattı üzerinde seçilen bir bölge için yapılan olasılıksal sismik tehlike analizlerine bağlı olarak önerilmiştir. Sonuçlar farklı zemin türleri ve farklı dönüş periyotlarına göre elde edilmiştir. Olasılıksal sismik tehlike analizleri için alansal kaynak ve fay ve mekansal düzleştirilmiş kaynak model olmak üzere iki farklı sismik model kullanılmıştır. Yer hareketi karakterizasyonu bölgedeki sismik aktiviteyi en iyi şekilde temsil edebilecek yer hareketi tahmin denklemlerinin seçilmesiyle yapılmıştır. Sabit ivme bölgesi köşe periyotları ve zemin faktörlerinin hesabı PGA veya T = 0.2 s ve 1.0 s’ deki kaya zemin spektal ivme değerlerine bağlı olarak üretilen ampirik bağıntılara dayanmaktadır.
