Master Thesis Çelik Lifli Betonun Çekme ve Basınç Altındaki Davranışı(2015) Abdussalam, Alfadhıl. A. Gheıt. Alfadhıl; Mertol, Halit Cenan; Baran, ErayÇelik lifli beton, içinde belirli uzunluktaki çelik liflerin gelişigüzel ve düzgün bir şekilde yayılımı ile elde edilen bir beton karışımıdır. Liflerin kalitesi ve miktarı betonun mekanik özelliklerini etkilemektedir. Çelik liflerin betona katılması, betonun çekme tokluğunu ve sünekliğini arttırdığı, basınç dayanımını da ufak da olsa iyileştirdiği genel olarak kabul edilmiştir. Betonun kırılmasından sonra çekme gerilmelerinin lifler arasındaki dağılımı sağlandığından dolayı çelik liflerin yararı daha belirgin olarak görülmektedir. Bu araştırmanın amacı, çelik lifli betonun çekme ve basınç altındaki davranışının, konvansiyonel ve çelik lifli beton kullanılan çeşitli numuneler üzerinde uygulanan yükleme deneyleri ile incelenmesidir. Deney numuneleri basınç silindirlerinden (100×200 ve 150×300 mm), prizmatik eğilme dayanımı elemanlarından (150×150×600 mm) oluşmaktadır. Ayrıca çelik donatıyı çevreleyen prizmatik beton numuneler üzerinde çekme deneyleri gerçekleştirilmiştir. Çelik donatı çevresindeki prizmatik numuneler için gerçekleştirilen çekme deneylerinde beton prizmaların uzunlukları (500, 1000, ve 1500 mm) ve kesit boyutları (60×60, 100×100,150×150, 200×200 mm) değişkenler olarak uygulanmıştır. Yük-deformasyon davranışları elde edilmiş ve çelik lifli betonun basınç ve çekme altındaki gerilme-birim uzama ilişkileri bulunmuştur. Prizmatik eğilme numunelerinden elde edilen yük-deformasyon davranışları, bu araştırmada bulunan basınç ve çekme altındaki gerilme-birim uzama ilişkileri kullanılarak tahmin edilen yük deformasyon davranışları ile karşılaştırılmıştır. Ayrıca literatürde bulunan farklı gerilme-birim uzama modelleri kullanılarak davranışlar yeniden tahmin edilmiştir.Master Thesis Farklı Katmanlarda Normal ve Çelik Lifli Beton Kullanılan Betonarme Kirişlerin Eğilme Davranışı(2015) Faeq, Mohammed Nozad Faeq; Mertol, Halit Cenan; Baran, ErayBu çalışmada farklı katmanlarda normal ve çelik lifli beton kullanılan betonarme kirişlerin eğilme davranışı incelenmiştir. 180×250×3500 mm boyutlarındaki beşer numuneden oluşan iki grup şeklindeki kirişler dört nokta eğilme yüklemesi altında test edilmiştir. İki grup kirişte de 416 betonarme çeliği kullanılmıştır. Bu araştırmadaki ana değişken, kiriş numunelerinin yüksekliği boyunca bulunan katmanlarda kullanılan beton tipidir. Kiriş numunelerinin kesit yüksekliği 50'şer mm kalınlığında 5 katmana ayrılmıştır. 'F' grubu numunelerde, normal beton katmanlarından oluşan kirişlere, aşağıdan başlayarak, çelik lifli beton katmanlar eklenmiştir. 'P' grubu numunelerde ise çelik lifli beton katmanları kesit üst seviyesinden başlanarak eklenmiştir. Yükleme deneyleri sonucunda kiriş numunelerinin yük-deformasyon davranışları elde edilmiş ve bu davranışlar yük taşıma kapasitesi, servis rijitliği, kapasite sonrası eğim ve tokluk paratmeleri göz önüne alınarak değerlendirilmiştir. Kiriş numunlerinin yük-deformasyon davranışlarının, literatürde bulunan malzeme modelleri kullanılarak sayısal olarak belirlenmesi için analitik bir çalışma gerçekleştirilmiştir.Article Citation - WoS: 21Citation - Scopus: 28Damage in Reinforced-Concrete Buildings During the 2011 Van, Turkey, Earthquakes(Asce-amer Soc Civil Engineers, 2014) Baran, Eray; Mertol, Halit Cenan; Gunes, BurcuTwo major earthquakes with magnitudes Mw=7.2 (ML=6.7) and ML=5.6 occurred in eastern Turkey on October 23 and November 19, 2011. The maximum measured peak ground accelerations for the two ground motions were 0.18g and 0.25g, respectively. The earthquakes resulted in various levels of damage to RC moment-resisting frame buildings ranging from minor cracking in brick partition walls to total collapse. This paper summarizes the field observations of the Atilim University Reconnaissance Team carried out in the region a few days after the two main shocks with an emphasis on the performance of RC buildings. A summary of the evolution of the Turkish seismic design code during the last 35 years is given, followed by an explanation of the behavior of RC buildings during the October 23 and November 9 earthquakes. The deformation types that were commonly observed in the heavily damaged or collapsed RC buildings include plastic hinging in columns attributable to stiffer beams, localization of damage in ground-story columns attributable to changes in the stiffness of the lateral load-resisting system caused by brick partition walls, and shear failure of columns caused by discontinuities in the partition walls adjacent to the columns. Poor concrete quality, inadequate development and lap splice length for reinforcement, and inadequate confinement in columns also contributed to the poor seismic behavior.Article Citation - WoS: 100Citation - Scopus: 114Flexural Behavior of Lightly and Heavily Reinforced Steel Fiber Concrete Beams(Elsevier Sci Ltd, 2015) Mertol, Halit Cenan; Baran, Eray; Bello, Hussain JibrilFlexural behavior of lightly and heavily reinforced steel fiber concrete beams was investigated. The test series consisted of 20 singly reinforced beams having 180 x 250 x 3500 mm dimensions. The main parameters in the testing program were the type of concrete and the amount of longitudinal reinforcement. Ten different longitudinal reinforcement ratios (with a minimum of 0.2% and a maximum of 2.5%) covering the range from under-reinforced to over-reinforced beam behavior were used in the testing program. Two specimens were cast for each longitudinal reinforcement ratio, one specimen using conventional concrete (CC) and another specimen using steel fiber reinforced concrete (SFRC). Load-deflection behaviors were obtained and evaluated in terms of ultimate load, ultimate deflection, service stiffness, post-peak stiffness, and flexural toughness. The results indicate that the use of SFRC increases the ultimate load and service stiffness of the beams slightly compared to that of CC specimens. As reinforcement ratio increases, the ultimate deflection of SFRC specimens becomes significantly greater than that of CC specimens. For over-reinforced sections, the post-peak stiffness of the SFRC specimens is observed to be significantly lower than that of CC specimens. The flexural toughness of SFRC specimens is greater than that of CC specimens with the difference being significantly larger for over-reinforced sections. Experimental load-deflection relationships were also compared to the load-deflection curves obtained from sectional analyses based on strain compatibility and best fit stress-strain relationships for SFRC in tension and compression.

A total of 25 beams, including FRP-, steel- and hybrid FRP-steel reinforced ones, were tested to failure under four-point bending. Two types of FRP bars, GFRP (Glass Fiber Reinforced Polymer) and BFRP (Basalt Fiber Reinforced Polymer), were used and both over- and under-reinforced beams were tested. The beams in each group were designed to have close flexural capacities to fully reveal the effect of FRP proportion in the tension zone on beam ductility for a fixed bending capacity. A new analytical model was developed for estimating the bending capacities of beams. Different deformation and curvature ductility definitions were adopted and an energy-based definition, revealing the expected tendency in beam ductility, was determined. The test results revealed that the presence of even a single FRP bar in the tension zone results in reductions up to 40% in beam ductility as compared to the beam with full steel reinforcement. Each additional replacement of a steel bar with FRP was found to cause a further decrease up to 20% in beam ductility.
