The construction of river bridge requires placement of bridge piers within the river. These piers obstruct the flow and may cause an increase in water level on the upstream side of the bridge. This increase in water level has a negative impact on the stability of bridge and may be responsible for scouring action around the bridge pier. The shape of the bridge pier is an important factor. Since 20th century on, streamlined shapes for bridge piers are being used. It is also known that for the first time in history, Mimar Sinan has used streamlined shapes for bridge piers in 16th century. However, there is a historical bridge in Diyarbakır, called Ongözlü Bridge which was built in 1065, that has streamlined shaped piers on Tigris River. In the present work, the characteristics of the shape of piers of Ongözlü Bridge is studied numerically using Flow 3D computational fluid dynamics (CFD) sofware. Pier of Ongözlü Bridge is compared with the drag characteristics of the other shapes that have been used as piers in the literature. The results show that even at 11th century, the hydraulic works in Anatolia were ahead of its time, and the first bridge with a streamlined shape was built 3-4 centuries before Mimar Sinan.

Local scour characteristics around semi-circular end bridge abutments with and without collars
Tekin, Fatime; Köken, Mete; Department of Civil Engineering (2012)
The major damage to bridges occurs due to scour of the bed materials around piers and abutments during severe floods. This study involves the experimental investigations of the various scour patterns forming around abutment models tested with and without collars as scour countermeasures. The experiments were conducted in a rectangular channel under clear-water scour conditions. In the first part of this study, 34 experiments were conducted with semi-circular end abutment models with and without a collar for...
Reliability based evaluation of seismic design of Turkish bridges by using load and resistance factor method
Yılmaz, Seyit Alp; Caner, Alp; Department of Civil Engineering (2014)
This study aims to evaluate the safety level of seismic design of Turkish highway bridge pier columns with respect to reliability theory. Evaluation of bridges was performed for four different codes of American Association of State Highway and Transportation Officials (AASHTO). Reliability indices were calculated for AASHTO Load and Resistance Factor Design 2010 (AASHTO LRFD 2010), AASHTO LRFD 2007, AASHTO Standard Specifications of Highway Bridges (LFD 2002) and Turkish modification of AASHTO LFD 2002 (cur...
Modeling temporal variation of scouring at dual bridge piers
Selamoğlu, Meriç; Yanmaz, Ali Melih; Köken, Mete; Department of Civil Engineering (2015)
Computation of temporal evolution of scour depth around bridge piers is essential for the efficient design of bridge pier footings. In this thesis, empirical scour-prediction equations and a semi-empirical model are developed to predict the temporal variation of maximum clear-water scour depth at dual cylindrical uniform piers with identical size in tandem arrangement. Experiments are conducted using different pier size, pier spacing, and flow intensities. The semi-empirical model is based on sediment conti...
Scour and scour protection at bridge abutments
Kayatürk, Şerife Yurdagül; Göğüş, Mustafa; Department of Civil Engineering (2005)
Bridge failures are mainly caused by scouring the bed material around bridge foundations during flood. In this study, scour phenomenon around bridge abutments is experimentally studied. Effect of abutment size, location and size of the collars placed around the abutments, time evaluation of scour hole around the abutment, scour characteristics of abutment and pier interaction were experimentally investigated. Scour measurements were conducted in a rectangular channel of 30 m long and 1.5 m wide filled with ...
Computer-assisted design methodology for bridge scour counter measures
Yıldırım, Mehmet Sinan; Yanmaz, Ali Melih; Department of Civil Engineering (2013)
Scour at bridge piers is considered as a significant safety hazard. Hence, scour countermeasure design plays a critical role to hinder the scour potential at bridges. The selection methodology for a scour countermeasure varies with respect to site conditions, economy, availability of material and river characteristics. The aim of this study is to review the literature on this topic to gather universally accepted design guidelines. A user-friendly computer program is developed for decision-making in various ...
