The objective of this study is to develop a performance-based earthquake engineering (PBEE) framework for the liquefaction-related hazards and estimate the hazard levels for liquefaction-related engineering demand parameters (EDPs) in a probabilistic manner. Two efficient, sufficient, and hazard compatible EDPs: probability of liquefaction (PL) and post-liquefaction settlement (δL) are selected. Seismic demand models that explain the relationship between these EDPs and ground motion IMs are employed in a semi-deterministic seismic hazard analysis. Results of the analysis are presented in terms of EDP vs. rupture distance and peak ground acceleration (PGA) plots. Two damage measures; 50% PL and 10 cm δL in Mw ≤ 7.0 earthquakes are defined. The cut-off rupture distance which should be used to select a distance range for considering the liquefaction-related hazards is defined for these damage measures and calculated for a 10 m liquefiable soil column. Similarly, the cut-off PGA below which the PL < 50% or δL < 10 cm for Mw ≤ 7.0 earthquakes are calculated since the design PGA is provided in codes and regulations and the PGA threshold for considering the liquefaction-related hazards is valuable in practical applications. Variation in the cut-off parameters with the change in soil properties is thoroughly discussed.

Using a performance-based earthquake engineering (PBEE) approach to estimate structural performance targets for bridges
Gülerce, Zeynep (2013-01-01)
Performance-based seismic evaluation aims to provide information on expected seismic performance of structures in measurable and meaningful terms for decision makers (performance objectives). The Pacific Earthquake Engineering Research (PEER) Center utilized the performance-based earthquake engineering (PBEE) framework by linking the earthquake scenarios, design ground motions, structural demand, and performance variables. PBEE procedure may be simplified by decoupling the evaluation of the design ground mo...
Modelling the Dynamic Response of Pile Foundations in Performance Based Geotechnical Engineering Framework
Unutmaz, Berna; Gülerce, Zeynep (2016-06-26)
The objective of this study is to develop a performance-based earthquake engineering (PBEE) framework for the soil liquefaction-related hazards and estimate the levels of exceeding liquefaction related engineering demand parameters (EDPs) in a probabilistic manner. The post-cyclic lateral deformation at the pile head (x) is tried to be predicted from ground motion intensity measures (IMs) such as peak ground acceleration (PGA) and Arias Intensity (I a). Within this scope, a number of finite difference anal...
Verification of empirically determined support systems of the Kılıçlar highway tunnel by numerical modelling
Çelik, Gözde; Topal, Tamer; Department of Geological Engineering (2011)
The aim of this study is to determine the geological and geotechnical characteristics of Kılıçlar Tunnel on Ankara-Kırıkkale Highway, to suggest the appropriate support and excavation systems and verify these suggested support systems via numerical modeling. The length of Kılıçlar Tunnel is 1110 m. The width of tunnel is 16 m, the height is 10 m and the maximum overburden height is 90 m. Since Ankara-Kırıkkale Highway consists of 2x3 lanes, the tunnel is designed as a twin tube tunnel. Kılıçlar Tunnel is pl...
Probabilistic models for the initiation of seismic soil liquefaction
Çetin, Kemal Önder; Kiureghian, AD; Seed, RB (2002-01-01)
A Bayesian framework for probabilistic assessment of the initiation of seismic soil liquefaction is described, A database, consisting of post-earthquake field observations of soil performance, in conjunction with in situ "index" test results is used for the development of probabilistically-based seismic soil liquefaction initiation correlations. The proposed stochastic model allows full and consistent representation of all relevant uncertainties. including (a) measurement/estimation errors, (b) model imperf...
Kırılganlık eğrileri kullanılarak elde edilen tahmini hasar dağılımının hasar tespit verileriyle karşılaştırılması
Çetin, Can; Erberik, Murat Altuğ (null; 2017-10-13)
Genellikle sismik risk değerlendirmelerinde kayıp ve hasarın tahmini için kullanılan kırılganlık eğrileri belirli bir ülke veya bölgede benzer özelliklere sahip yapı tipleri için oluşturulur. Bölgesel özellikleri esas alan kırılganlık eğrilerinin oluşturulması genel anlamda zor ve zahmetli bir iş olduğundan hasar ve kayıp tahminleri için çoğunlukla uluslararası çalışmalar sonucu oluşturulmuş mevcut kırılganlık eğrileri kullanılmaktadır. Oysa ülke veya bölge yapı stoğunu temsil etmeyen kırılganlık eğrilerini...
