Inspection and evaluation of a network of concrete bridges based on multiple NDT techniques
Akgül, Ferhat (Informa UK Limited, 2020-07-01)
Bridge condition rating is a crucial variable used for prioritisation of bridge needs in bridge management systems (BMSs). At present, bridge rating is predominantly based on visual inspections. A practical method incorpor...
Time-variant reliability analysis incorporating multiple deterioration and live load models
Berenji, V. G.; Akgül, Ferhat (2016-10-20)
Bridge elements deteriorate with time due to exposure to different environmental attacks, distress mechanisms and live loads effects. In order to optimize the time-variant life-cycle costs or to obtain realistic time-varia...
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...
Development of a bridge management system incorporating a newly developed model for element condition evaluation based on damage effects
Akgül, Ferhat (2013-12-01)
This article presents a comprehensive research project undertaken for the development of a bridge management system (BMS) for the General Directorate of Highways in Turkey, establishment of a prototype inspection program a...
A BMS development project with an integrated inspection program
Akgül, Ferhat (2012-07-12)
A bridge management system is being developed together with an integrated inspection program. A pilot bridge group consisting of 200 bridges is selected for inspections which are located along the state and provincial road...
Probabilistic performance prediction modeling for bridges considering maintenance effects within a combined computation, visualization and programming environment
Akgül, Ferhat (2010-07-15)
Various models have been developed in recent past for lifetime performance prediction of bridges. Studies for developing new theoretical models and improvement of the existing ones are part of ongoing research in bridge de...
Criteria for a bridge management system based on inspection, monitoring and maintenance practices
Akgül, Ferhat (2006-10-18)
Numerous bridge management systems have been developed around the world for different bridge administrations and agencies. These systems are mostly built on common tasks and models aiming at cost optimal maintenance of a b...
Lifetime Performance Analysis of Existing Reinforced Concrete Bridges. II: Application
Akgül, Ferhat; Frangopol, Dan M. (American Society of Civil Engineers (ASCE), 2005-06-01)
This study, being the second part of a two-part paper, presents the application of a lifetime performance analysis methodology to three reinforced concrete bridges located in an existing bridge network in Colorado. The foc...
Lifetime Performance Analysis of Existing Reinforced Concrete Bridges. I: Theory
Akgül, Ferhat; Frangopol, Dan M. (American Society of Civil Engineers (ASCE), 2005-06-01)
In this first part of a two-part paper, a general methodology for lifetime performance analysis of existing reinforced concrete bridges is presented. The framework for the methodology is established by identifying four dis...
Lifetime performance analysis of existing prestressed concrete bridge superstructures
Akgül, Ferhat; Frangopol, DM (American Society of Civil Engineers (ASCE), 2004-12-01)
A general methodology for lifetime performance analysis of existing prestressed concrete girder bridges is presented. Only the superstructure components (slab and girders) are considered. The framework for the methodology ...
