Assessment of the reliability of lifelines under seismic loads requires particular attention, since the proper functioning of these systems during or after a destructive earthquake is very important. The main objective of this study is to investigate the system reliability of lifeline networks subjected to earthquake loads by concentrating on highway transportation systems consisting of viaducts, bridges, roads, and highways. Seismic reliability of a structural component is determined based on the seismic capacity of the component and earthquake loads acting on it. The future earthquake threat on the components is calculated by performing a probabilistic seismic hazard analysis. Failure reasons of bridges and asphalt roads are explained and behavior of these components under earthquake loads is discussed to determine the seismic capacities of them. In this respect, the system reliability concepts are used and bounds on the seismic reliability of a system are established. A case study based on real-life data is also presented in order to illustrate the implementation of the method. (C) 2018 American Society of Civil Engineers.

Seismic fragilities for non-ductile reinforced concrete frames - Role of aleatoric and epistemic uncertainties Çelik, Ozan Cem (2010-01-01) Seismic fragilities are essential to earthquake loss estimation and performance-based earthquake engineering in regions of high seismicity. Construction practices for frames in regions of moderate seismicity are quite different, and such frames have received less attention in the literature. Fragilities for performance levels identified in recent seismic regulations are developed herein for reinforced concrete frames designed for gravity load in low-seismic regions using probabilistic non-linear finite elem...
Ground motion simulations based on regional input parameters and their impact on insurance premiums: Bursa case Ünal, Barış; Askan Gündoğan, Ayşegül; Kestel, Sevtap Ayşe; Department of Earthquake Studies (2015) Determination of earthquake parameters are required for earthquake resistant design and retrofitting of exsisting structures. There are not many options to obtain earthquake data for regions with no or sparce earthquake recordings. Even though some methods are aplicable to these regions they generate only peak ground motion parameters. For cases that require the full ground motion simulations are necessary. Simulations can also be used for gaining knowledge about source, path and site effects. In this study...
SEISMIC HAZARD ANALYSIS WITH RANDOMLY LOCATED SOURCES Yücemen, Mehmet Semih (1994-03-01) Demarcation of areal and linear seismic sources involves a certain degree of uncertainty and this should be reflected in the final seismic hazard results. The uncertainty associated with the description of the geographical coordinates of a source zone boundary is modeled by introducing the concept of 'random boundary', where the location of the boundary is assumed to exhibit a spatial bivariate Gaussian distribution. Here the mean vector denotes the best estimate of location and the variance reflects the ma...
Investigation of seismic isolation efficiency for building structures Özdemir, Seda; Yakut, Ahmet; Ay, Bekir Özer; Department of Earthquake Studies (2016) The main goal of this study is to assess the efﬁcacy of seismic isolation for building type of structures with different structural systems, namely, dual systems and moment frame systems having also different number of ﬂoors. Speciﬁc to this study, the main parameters employed for efﬁcacy assessment will be the interstorey drift ratio and ﬂoor acceleration since both structural and non-structural damage to be occured in a system are directly related to these two parameters. To assess the variations in inter...
Performance Assessment of Turkish Residential Buildings for Seismic Damage and Loss Estimation Un, Elif M.; Erberik, Murat Altuğ; Askan Gündoğan, Ayşegül (2015-04-01) This study aims to present an integrated method in a probabilistic manner for seismic performance assessment of Turkish residential buildings, which can be used as a tool to estimate earthquake losses due to structural damage. In particular, the objective is to determine the performances of different types of residential buildings for predicting the potential seismic loss in terms of casualties (death toll) for a highly populated city in northwestern Turkey. The main phases of this study are seismic hazard,...
