In Turkey, bridge design procedure has been followed from a modified version of the AASHTO LFD (Load Factor Design) or ASD (Allowable Stress Design) requirements until now. The recent switch of the US bridge codes to LRFD method also necessitates the calibration of the new design of the Turkish bridges according to the LRFD system. The main aim of this study is to develop the load and resistance factors to be implemented in the design of steel composite I-girders of cable-stayed bridges (span lengths 420 m to 550 m) for the basic gravity load combination. Moreover, the performance of new type of live (truck) load of Turkish LRFD, namely, AYK-45 is evaluated. In such studies, usually a target reliability index is selected to reflect the safety level of current design practice based on the uncertainties associated with the design parameters. For the basic gravity load combination, which includes the dead and live loads, a minimum target reliability of 4.30 is selected, instead of 3.50 that have been used in US. In the statistical computations of the reliability index, the quantification of uncertainties is made based on local data supplemented by information compiled from relevant international literature.

Effect of vehicular and seismic loads on the performance of integral bridges
Erhan, Semih; Dicleli, Murat; Department of Engineering Sciences (2011)
Integral bridges (IBs) are defined as a class of rigid frame bridges with a single row of piles at the abutments cast monolithically with the superstructure. In the last decade, IBs have become very popular in North America and Europe as they provide many economical and functional advantages. However, standard design methods for IBs have not been established yet. Therefore, most bridge engineers depend on the knowledge acquired from performance of previously constructed IBs and the design codes developed fo...
Bridge management in Turkey: a BMS design with customised functionalities
Akgül, Ferhat (2016-05-03)
The overall design and customised functionalities of a bridge management system (BMS), developed in Turkey in 2009-2013 period (the so-called KYS), are presented. The novel design features are explained. Development of the web-based BMS involved the establishment of a bridge inventory database, a detailed multi-layer cost database with an itemised unit cost breakdown capability, inventory management, cost and planning modules, optimal allocation of maintenance-repair-replacement (MR&R) budgets while produci...
Comparison of ASCE/SEI standard (2010) and modal pushover based ground motion scaling procedures for pre-tensioned concrete bridges
Özgenoğlu, Müge; Arıcı, Yalın; Department of Civil Engineering (2015)
The seismic design and evaluation of large bridges is a demanding task owing to the significant size and the structural characteristics of these systems. Although elastic analysis methods are regarded as sufficient for common, uncritical bridges; complex analysis methods such as non-linear time history analysis (NTHA) are often required for non-standard and/or important bridges. The selection of the ground motions that will be used in non-linear time history analysis is a crucial task in this regard as the ...
Multi-support seismic excitation of long span highway bridges
Gökdemir, Tunç; Askan Gündoğan, Ayşegül; Caner, Alp; Department of Civil Engineering (2017)
Seismic design and analysis are common practices in bridge engineering which require both knowledge and experience. Technical standards, such as CALTRANS (2010) and AASHTO (2007) provide guidance on the analysis with the methods ranging from Response Spectrum Analysis (RSA) to Time History Analysis (THA). These methods are usually sufficient for obtaining the seismic behavior of common structures and capture the dynamic behavior with decent accuracy. However, this may not be the case for structures which sp...
Development of the bridge management system for Turkey by introducing a condition rating model based on damage types
Masoumi, Faraz; Akgül, Ferhat; Department of Engineering Sciences (2014)
The decisions regarding the maintenance, repair and replacement of bridges in developed countries are being made using databases and programs built on scientific and technical knowledge. The computer programs that are developed for this purpose are referred to as Bridge Management Systems (BMS; KYS in Turkish). The main function of a Bridge Management System is to keep the maintenance, repair and replacement costs of bridges at an optimum level throughout the bridge lifetime, to continuously sustain the saf...
