Analysis of reinforced concrete columns retrofitted with fiber reinforced polymer lamina
Binici, Barış (2007-01-01)
Fiber reinforced polymer (FRP) lamina have been used widely in the last decade to enhance strength and deformation capacity of deficient reinforced concrete (RC) columns. Seismic assessment and retrofit of existing columns in buildings and bridge piers necessitate accurate prediction of the available deformation capacity. In this study, a new analytical model is proposed to represent potential plastic hinge regions of RC columns prior to and after FRP retrofit. A recently developed variable confined concret...
Analysis of sinusoidal and helical buckling of drill string in horizontal wells using finite element method
Arpacı, Erdoğan; Özbayoğlu, Evren; Department of Petroleum and Natural Gas Engineering (2009)
The number of horizontal wells is increasing rapidly in all over the world with the growth of new technological developments. During horizontal well drilling, much more complex problems occur when compared with vertical well drilling, such as decrease in load transfer to the bit, tubular failure, tubular fatigue and tubular lock-up. This makes selection of appropriate tubular and making the right drill string design more important. As the total compression load on the horizontal section increases, the behav...
Analysis of sinusoidal buckling of drill string in vertical, directional and horizontal wells using finite element method
Kök, Mustafa Verşan; Gücüyener, Hakkı (null; 2019-03-21)
The present work focuses on the stability of drill strings in vertical wellbores. The first rigorous treatment of stability of drill strings for vertical wellbores was presented by Lubinski (1950) and his equation is till most widely used in the industry. Cunha (2004) stated that since Lubinski (1950) used power series to solve differential equation governing the stability problem, and the terms of power series become very large for long drill strings, therefore, after a certain length, the calculations may...

Analysis of corner effects on in-situ walls supporting deep excavations: comparison of plane strain and three dimensional analysis
Ünlü, Güliz; Erol, Orhan; Department of Civil Engineering (2008)
In this thesis, hypothetical cases of in-situ walls, that are supported at one, two and four levels, as well as cantilever walls, are analyzed using plane strain and 3D finite element programs. A parametric study is performed by varying the soil stiffness. Deflection, moment, anchor loads and effective lateral earth pressures acting on the walls are examined to understand corner effect. Comparisons are made between plane strain and 3D without corner analysis results to confirm that two programs yield simila...
