© 2021 Taylor & Francis Group, LondonUnder the sponsorship of General Directorate of Highways of Turkey, a new specification is developed for the seismic isolation design of highway and railway bridges. This paper describes the distinct features of the newly developed seismic isolation bridge design specifications of Turkey in comparison to AASHTO Guide Specifications for Seismic Isolation Design of Bridges and EN15129: European Standard on Anti-Seismic Devices. The comparative study is performed for different sections of the design specifications including the parts related to; (i) the classification of bridges for analysis and design, (ii) seismicity and design response spectra, (iii) equivalent linear and time history analyses, (iv) types of seismic isolation and energy dissipation devices covered in design specifications, (v) design of seismic isolation and energy dissipation devices, and their minimum testing requirements and (vi) minimum requirements of seismic isolation and energy dissipation devices to ensure continued functionality and serviceability of the bridge. The comparative study revealed that the new Bridge Seismic Isolation Design Specifications of Turkey differs in many ways compared to AASHTO and EN15129 including the approaches related to the seismicity and design spectra with particular emphasis on near-field effects, minimum requirements for the serviceability of bridges, property modification factors used for seismic isolation and energy dissipation devices as well as testing procedures.

Development of a Bridge Inspection and Management Project Akgül, Ferhat (2010-09-24) A research project is undertaken for the combined inspection and management of a pilot group of road bridges in Turkey based on the development of a bridge management system (BMS) for the General Directorate of Highways. The pilot study consists of visual inspections of 200 bridges and detailed inspections of 10 bridges. Visual inspections are planned to be carried out by photogrammetric techniques while detailed inspections will include techniques such as strength determination using probe test systems, ul...
Engineering geological investigations and the preliminary support design for the proposed Ordu Peripheral Highway Tunnel, Ordu, Turkey Sopaci, Evrim; Akgün, Haluk (Elsevier BV, 2008-01-07) This paper presents engineering geological investigations and the tunnel support design for the Boztepe tunnel of the Ordu Peripheral Highway located in northeast Turkey. In order to characterize the rock masses in Boztepe Tunnel which mainly consist of flysch (mostly alternation of sandstone, marl and siltstone) and pyroclastics (agglomerate and tuff), engineering geological investigations have been carried out in three stages as surface, subsurface and laboratory investigations. Rock mass classification s...
Tarihi Kurt Köprüsü (Mihraplı köprü, Vezirköprü) Restorasyonu Proje Ve Uygulama Çalışmaları Halifeoğlu, F.Meral; Sert, Halide; Yılmaz, Süheyla (Middle East Technical University, Faculty of Architecture, 2013-12-1) Apart from the construction of the new roads and bridges, it is one of the principal duties of the General Directorate of Highways to repair and maintain the historical bridges in accordance with the projects to be produced or caused to be produced by the General Directorate of Highways. Pursuant to the inventory records of historical bridges (kept until December 2012), it has been observed that there exist a total of 1646 each bridges in our country which is located on First Degree Seismic Zone, dating bac...
Stability analysis of a coupled structure: a railway tunnel and a road cut slope Ünlütürk, Burcu; Bilgin, Hasan Aydın; Department of Mining Engineering (2018) A road-cut slope is planned for the construction of a new highway at Zonguldak province. This slope will be excavated by bench blasting method in close proximity to the No 50 Turkish State Railway Tunnel which is a masonry lined 84 years old tunnel in service. The excavation will continue until –approximately- 56 m horizontal and 55 m vertical distances remain to the tunnel lining. The plane failure risk of the slope and the damage risk of the tunnel are two major risks. Investigating stability of the slope...
Determination of the rock mass characteristics and support systems of the new Ulus Tunnel, Ankara Aksular, Irem; Doyuran, Vedat; Department of Geological Engineering (2008) The New Ulus Tunnel will be constructed within the andesitic terrain at Hıdırlıktepe (Ankara). Excavation of the tunnel will be accomplished through blast and drill method. Emprical methods will be consulted during the design of the support systems as well as the slope of the portal rock face. Therefore it is essential to perform detailed rock mass characterization studies. In this thesis it is aimed to determine the rock mass characteristics in order to design the rock slope of the portals and to assess th...
