Drag characteristics of a historical bridge pier
Bülbül, Mehmet Mert; Denli Tokyay, Nuray; Department of Civil Engineering (2017)
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 hi...

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...
Lifetime condition prediction for bridges
Bayrak, Hakan; Akgül, Ferhat; Department of Engineering Sciences (2011)
Infrastructure systems are crucial facilities. They supply the necessary transportation, water and energy utilities for the public. However, while aging, these systems gradually deteriorate in time and approach the end of their lifespans. As a result, they require periodic maintenance and repair in order to function and be reliable throughout their lifetimes. Bridge infrastructure is an essential part of the transportation infrastructure. Bridge management systems (BMSs), used to monitor the condition and s...
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...
