    Investigation of Reinforcement Corrosion Effects in Rc Columns Produced With Blast Furnace Slag and Fly Ash Under Reversed-Cyclic Lateral Loading Tests
    (ELSEVIER SCI LTD, 2021-10-01) Koçer, Mustafa; Boğa, Ahmet Raif; Öztürk, Murat
    Corrosion, which threatens reinforced concrete structures throughout their service life, adversely affects the earthquake performance of the structures. For countries located in an active earthquake zone, it is of great importance to investigate the behavior of reinforced concrete structures exposed to corrosion damage under lateral load. For this purpose, the effect of the use of blast furnace slag (BFS) and fly ash (FA) in certain proportions by weight of CEM I 42.5R cement on the reinforcement corrosion inside the RC column and the positive/ negative contribution to the behavior of the columns under lateral load were experimentally investigated. Within the scope of this study, firstly three RC column specimens without any mineral admixture were produced as CONTROL series. In the mineral admixture series, a total of 12 RC column specimens, 3 from each series, were produced by using 20% and 40% BFS, 10% and 20% FA of the cement amount instead of cement, respectively. One of the three columns produced for each series was selected as a reference, and the remaining two-column specimens were exposed to corrosion under constant voltage until theoretically 10% and 30% weight losses were achieved, respectively, using the Faraday Equation in the reinforcements. After the accelerated corrosion tests, the RC columns were tested under reversed-cyclic lateral loading reflecting the earthquake effect. Experimental results show that the use of mineral admixtures in concrete production reduces the risk of corrosion of reinforced concrete elements and improves earthquake behavior.

    Determination of Moment, Shear and Ductility Capacities of Spiral Columns Using an Artificial Neural Network
    (ELSEVIER, 2019-11-01) Koçer, Mustafa; Öztürk, Murat; Arslan, M. Hakan
    Intelligent systems are frequently used to solve difficult and complex problems in today's world. Especially in the discipline of civil engineering, much research has been conducted with the help of intelligent systems. The objective of this study is to identify the moment and shear force capacities of reinforced concrete spiral columns and their displacement ductility values by using an algorithm based on an Artificial Neural Network (ANN). In the study, 86 different spiral column experiments tested in the literature were compiled, and the moment and shear force capacities obtained through the experiments were arranged at a certain level. In addition, the ductility values of the tested columns were calculated using graphical experimental data. The output layer consists of four neural network models, which are ANN(1) (with three output neurons), ANN(2), ANN(3), and ANN(4) (with one output neuron), and moment, shear force capacity, and displacement ductility parameters were obtained, respectively. According to results of this study, it was observed that moment and shear force capacities of spiral columns could be particularly well estimated using ANN. However, it was found that the estimation success of ANN for displacement ductility was not sufficient.

    Code-Based Damage Assessment of Existing Precast Industrial Buildings Following the February 6th, 2023 Kahramanmaraş Earthquakes (pazarcık Mw 7.7 and Elbistan Mw7.6)
    (Elsevier Ltd, 2024-06-01) Arslan, M.H.; Dere, Y.; Ecemiş, A.S.; Doğan, G.; Özturk, M.; Korkmaz, S.Z.
    In Turkey, a substantial portion of the industrial buildings consists of precast structures. Unfortunately, these buildings suffered significant damage, with some partially collapsing, during two consecutive earthquakes that occurred in Kahramanmaraş (Pazarcık Mw7.7 and Elbistan Mw7.6) on February 6, 2023. Consequently, numerous industrial facilities became unusable, leading to substantial economic losses. This article aims to identify the vulnerabilities of such buildings and assess their actual earthquake performance to prevent potential future damages. The authors collected data through field investigations conducted near the earthquake's epicenter, which were subsequently evaluated within the study. The research comprehensively examines the seismic characteristics of both earthquakes, the structural system of existing prefabricated industrial buildings in the region, and the relevant provisions outlined in the history of earthquake codes for prefabricated industrial buildings. Additionally, nonlinear finite element simulations of the heavily damaged hinged type of column-beam connections commonly employed in earthquake-prone areas are presented. The impact of manufacturing defects on the structural seismic behavior is also investigated. In the study's final stage, it is concluded that non-compliance with structural projects and relevant codes during the manufacture of connection regions in prefabricated industrial buildings is one of the primary causes of structural damage. Furthermore, it is observed that necessary measures should be implemented in these structures to enhance lateral stiffness in the roof plane, and the use of hinged column-beam joints should be avoided or restricted, especially in regions prone to earthquakes. The finite element model analysis reveals that the load-bearing capacity of the connection increases by 62% for lateral out-of-plane loading when grout mortar is applied. © 2024 Elsevier Ltd

    School Buildings Performance in 7.7 Mw and 7.6 Mw Catastrophic Earthquakes in Southeast of Turkey
    (Elsevier, 2023-11-01) Öztürk, Murat; Arslan, Musa Hakan; Doğan, Gamze; Ecemiş, Ali Serdar; Arslan, Hatice Derya
    Although Turkey is located in one of the active earthquake belts of the world, the 7.7 and 7.6 magnitude earthquakes that occurred on February 6, 2023, 9 h apart, as rarely seen in the seismology literature, caused one of the biggest disasters in Turkey's history. In the earthquakes affecting an area of approximately 110,000 square kilometers, serious damage and collapse occurred in public buildings as well as other structures. There are more than 12,000 school buildings in the earthquake-affected area and this number constitutes an important part of public buildings. This article deals with the damage types and causes of various public school buildings that were exposed to the earthquakes in southern Turkey on February 6, 2023. The seismicity of the region and the effects of the 6 February earthquakes were discussed, and the response spectra of the different regions most affected by the earthquakes were compared with the design spectra defined in the codes. In addition, during the field investigation the damage types and causes of damage in school buildings were listed in sections and the observations made with performance based analytical studies were supported. From field reconnaissance, the importance of understanding the deficiencies of school buildings, which have social priority, in order to avoid tragic consequences in possible earthquakes has been revealed.

    Üç Katlı Betonarme Bir Yapının Çeşitli Değişkenlere Bağlı Olarak Patlama Etkisi Altında Davranışının İncelenmesi
    (Konya Teknik Üniversitesi, 2023) Yaşar, Enes Barış; Öztürk, Murat
    Yapıların tasarımı mimari ve statik projeler tamamlanmasından sonra saha imalatlarıyla devam eder. Mimarisi tamamlanan projelerin statik tasarımı aşamasında ölü yük, hareketli yük, deprem yükü, rüzgâr yükü, sıcaklık etkisi, fiktif yük ve endüstriyel yapılarda kren yükü olarak yükler tanımlanmakta ve hesaplar bu yükler dikkate alınarak yapılmaktadır. Son yıllarda yaşanan patlayıcı depolarındaki patlamalar, terör faaliyetleri ve doğal kaynaklı patlamalardan kaynaklı yaşanan maddi ve manevi kayıplar özellikle bazı yapılarda patlama yüklerinin statik hesaplara dahil eğilmesi gerektiğini gözler önüne sermiştir. Bu tez çalışmasında; farklı miktarlardaki ve konumlardaki patlama yüklerinin üç katlı betonarme bir yapı üzerinde oluşturduğu etkiler araştırılmıştır. Bu kapsamda; patlama analizlerini yapabilen bir sonlu elemanlar yazılımı kullanılmıştır. Üç katlı betonarme bir yapı içerisinde farklı miktar ve konumlarda infilak eden patlayıcının oluşturduğu yüklerin yapının taşıyıcı ve taşıyıcı olmayan elemanları üzerindeki etkisi araştırılmıştır. Yapıların patlama yüklerine karşı dayanıklı tasarımının yapılması üretim alanında ilave maliyetlere sebep olacağı kaçınılmaz olsa da hastane, kamu binaları, askeri yapılar vb. kritik öneme sahip yapıların tasarımında dikkate alınmasının yaşanacak maddi kayıp açısından birçok zararın önüne geçeceği düşünülmektedir.

    Analytical Study on the Effect of Corrosion To the Construction Performance
    (2019) Koçer, Mustafa; Öztürk, Murat; Boğa, Ahmet Raif
    Corrosion is one of the most important factor to achieve in completing the service life of reinforced concrete structures also cause significant losses in energy damping capacities of structures. In this study, the reinforced concrete column designed in ½ geometrical scale was subjected to accelerated corrosion test for 26.5 days under 1 ampere constant current. As a result of the experiment, weight loss and strength reductions was obtained. Loss of strength in reinforcement due to corrosion damage was obtained with experimental procedure. Loss of cross section and reduction of compressive strength of concrete were obtained with empirical formulas in the literature. Thanks to this data, 3 different scenarios applied on a sample building in Hatay province. Static pushover analyzes of the sample building designed in accordance with the regulations were carried out with Sap 2000 program under the specified corrosion scenarios. The load-displacement curves obtained by the scenarios are compared with the curves of the reference building. As a result of the comparisons, it was observed that corrosion damage caused significant loss in horizontal load carrying capacity of the building. The corrosion scenarios show that corrosion in columns or beams changes collapse modes of the structure.

    The Effect of Different Seismic Isolator Types and Floor Number To Earthquake Behavior on Multi-Storey Reinforced Concrete Structures
    (2019) Hakan Abdülhamit Türk; Öztürk, Murat; Erkan, İbrahim Hakkı
    Earthquakes are uncontrollable natural disasters that cannot be predicted in time. Turkey, located in a region of high seismicity. Seismic isolation is an earthquake resistant structure design approach based on the principle of increasing the resistance of the structure against earthquakes or reducing the seismic forces transferred from the ground to the structure. In this study, an exemplary health center RC building system, carriage elements are dimensioned according to TS-500 (Turkey Concrete Structures Design and Construction Rules) and TBDY-2018 (Turkey Building Earthquake Regulation). 3 models were created for the same building according to three different types of support (with friction pendulum isolation system, lead core rubber bearing isolation system, fixed base dual system) .The most important aim of this study is to find out which of the seismic isolator type is more effective than fixed base dual systems. These models were analyzed nonlinear (FNA) in time domain in SAP2000 program. When compared with seismic isolator bearing systems and fixed base dual systems; the internal forces, the relative drift ratio(%) of the floor and the acceleration of the floor were decreased, but the natural vibration period was increased. The system with friction pendulum isolator has better earthquake behavior than the system with lead core rubber.

    Assessment of the Damage Caused by the 6 February 2023 Earthquakes on Old and New Dated Reinforced Concrete Buildings in Elbistan, Turkey
    (Sage Publications Inc, 2025-09-10) Aras, Fuat; Dogan, Talha Polat; Ozturk, Murat; Tun, Muammer; Isik, Ercan; Arslan, Musa Hakan
    On 06 February 2023, two strong earthquakes occurred in Kahramanmara & scedil;, T & uuml;rkiye. The first earthquake with a moment magnitude (Mw) of 7.7 and an epicenter in Pazarc & imath;k, was followed by a second earthquake with a moment magnitude of (Mw) 7.6 and an epicenter in Elbistan. These earthquakes have caused catastrophic life and structural loss in ten cities where more than 15 million people permanently live. Concentrating on the epicenter of the second earthquake, Elbistan, this study investigates the main characteristics of the earthquakes and the failure of the reinforced concrete buildings. Acceleration records from both earthquakes were analyzed and site surveys were conducted to evaluate the caused damages. The high number of completely collapsed buildings highlighted the vulnerability of the general old building stock constructed before 2000. Notably, unlike previous earthquakes in T & uuml;rkiye, these earthquakes also affected new buildings constructed according to the recent Turkish Earthquake Code. In that respect, seismic damages seen in these buildings are presented and interpreted in this paper. To validate the observed deficiencies, a damaged building whose construction had just been completed but not yet occupied was both surveyed on site and subjected to non-linear performance analyses. The analysis results demonstrated that the damage distribution and locations in the models closely matched the observed damage after the earthquakes. In addition, the analyses also revealed the effect of brick infill walls on the building's seismic behavior.

    Korozyon Etkisi Altındaki, Mineral Katkı ile Üretilen Kolonların Tersinir Tekrarlanır Yatay Yük Altındaki Davranışlarının Araştırılması
    (Konya Teknik Üniversitesi, 2020) Koçer, Mustafa; Öztürk, Murat; Boğa, Ahmet Raif
    Betonarme yapıları servis ömürleri boyunca tehdit eden korozyon, donatıya verdiği tahribattan dolayı yapıların yanal yer değiştirme kapasitelerini kaybetmesindeki başlıca etkenlerden biri olarak gösterilmektedir. Ülkemizde meydana gelen yıkıcı depremler sonrası yapılan saha incelemeleri, yıkılan veya ağır hasar gören yapıların büyük bölümünde donatıların korozyona uğradığını ve beton ile donatı arasındaki aderansın kaybolduğunu göstermektedir. Bunun yanında deprem sırasında yapı güvenliği açısından en kritik elemanların kolonlar olduğu bilinmektedir. Bu nedenle, özellikle korozyona uğramış betonarme kolonların yatay yük altındaki davranışlarını ve alınabilecek önlemleri araştırmak, Türkiye gibi aktif deprem kuşağı içinde yer alan bir ülke için büyük önem taşımaktadır. Bu tez çalışmasında, yüksek fırın cürufu (YFC) ve uçucu külün (UK), CEM I 42.5R çimentosunun yerine belirli oranlarda kullanımının, betonarme kolonun içerisinde ki donatı korozyonuna etkisi ve kolonların yatay yük altında davranışına olumlu/olumsuz katkısı deneysel olarak araştırılmıştır. Bu amaçla tez çalışması kapsamında, içerisinde hiçbir mineral katkının bulunmadığı 280 kg/m3 çimento dozajlı 3 adet betonarme kolon numunesi, KONTROL serisi olarak üretilmiştir. Mineral katkılı serilerde ise, çimentonun yerine çimento miktarının %20'si ve %40'ı oranında YFC, %10'nu ve %20'si oranında UK kullanılarak, her bir seriden 3'er adet olmak üzere toplam 12 adet betonarme kolon numunesi üretilmiştir. Her bir seri için üretilen üç adet kolondan biri referans olarak seçilmiş, geriye kalan iki kolon numunesinin donatılarda Faraday Denklemi kullanılarak teorik olarak sırasıyla %10 ve %30 ağırlık kayıpları oluşana kadar sabit voltaj altında korozyona maruz bırakılmıştır. Hızlandırılmış korozyon deneyleri sonrasında, numuneler deprem etkisini yansıtan tersinir-tekrarlanır yatay yük altında deneye tabi tutulmuştur. Yanal yükleme deneyinden sonra numunelerin içinden donatılar parça parça çıkartılarak özel solüsyonlarla (HCl asit çözeltisi) pas ve beton kalıntılarından arındırılmıştır. Böylece donatıların ağırlıkları tartılarak ilk ağırlıkları ile karşılaştırılmış ve numunelerde meydana gelen gerçek korozyon seviyeleri belirlenerek yorumlanmıştır. Deneysel sonuçlar, beton üretiminde mineral katkı kullanımının betonarme elemanların korozyon riskini azalttığı ve deprem davranışlarını iyileştirdiği görülmüştür.
