    HAFİF AGREGALI YAPISAL BETON VE TÜRKİYE GERÇEĞİ
    (Bilim ve Teknoloji, 2013) Tunç, Gökhan
    Türkiye‟deki inşaat sektörünün büyük çoğunluğubetonarme yapılardan oluşmaktadır. Betonarme, beton ve donatı çeliğinin birlikte çalışma ilkesine dayalı kompozit bir malzeme olarak tariflenebilir. Bu yazıda betonarmeyi oluşturan iki bileşenden beton malzemesi üzerine yoğunlaşılacaktır. Beton; içerisinde farklı karışım oranlarında çimento, agrega ve su ihtiva eden bir yapı malzemesi türüdür. Ülkemizde üretilen yapısal beton türü, birim hacim ağırlığı 2.4 t/m3 olarak tanımlanan normal ağırlıklı betondur. Gelişmiş ülkelerde ise normal ağırlıklı betonun yanında daha hafif agregalarla oluşturulan hafif ağırlıklı beton türünün de yapısal beton olarak yaygın bir şekilde kullanıldığını görmekteyiz.

    A Light Bulb in Every House the Istanbul General Electric Factory and American Technology Transfer To Turkey
    (Johns Hopkins Univ Press, 2022) Tunc, Tanfer Emin; Tunc, Gokhan
    In 1946, Turkish entrepreneur Vehbi Koc signed an agreement with the U.S. firm General Electric to build and operate its first light bulb factory in the Near/Middle East, in Istanbul. This private joint venture introduced new manufacturing techniques, business practices, and consumer habits to Turkey, opening channels of postwar technological exchange. Closer examination of the GE-Koc partnership reveals that during the early Cold War, the transfer and embedding of American technologies in Turkey was a politically complicated process of innovation that required constant adaptation. Fraught with unforeseeable obstacles, it also required cautious negotiation with multiple transnational actors. The story of the GE-Koc partnership thus adds a new dimension to historical understandings of the Turkish Cold War experience and the Americanization of the region. It illustrates how transferring a nonmilitary, soft-power, domestic technologythe light bulb-played a significant role in Turkish-American relations and therefore contributes to studies of U.S. Cold War diplomacy through transnational investment in innovation.

    A Site Survey of Damaged Rc Buildings in Izmir After the Aegean Sea Earthquake on October 30, 2020
    (Croatian Soc Civil Engineers-hsgi, 2023) Mertol, Halit Cenan; Tunc, Gokhan; Akis, Tolga
    An earthquake with a magnitude of Mw = 6.6 and a depth of approximately 16.5 km occurred on 30 October 2020 off the cost of Samos, a Greek island 35 km southwest of Seferihisar, a town in Izmir. The earthquake caused several collapses and severe structural damage in approximately 6,000 buildings, specifically in the Bayrakli District in Izmir Bay. This paper presents the observations and findings of a technical team that visited the earthquake -affected areas immediately after the earthquake. Eleven partially or fully collapsed and several severely damaged reinforced concrete buildings were investigated. Based on the site investigations, we observed that almost all of the collapsed or severely damaged reinforced concrete buildings in the region were built between 1975 and 2000. Site observations also confirmed that the construction of these collapsed or damaged buildings did not conform to the requirements outlined in the Turkish Earthquake Codes used at the time. The failures and severe damage to buildings in earthquake-affected areas are primarily related to inadequate reinforcement configuration, poor material quality, the absence of geotechnical studies, and framing problems related to their lateral load-carrying systems. Therefore, it is recommended that all the buildings located in and around Izmir Bay, particularly those built between 1975 and 2000, be structurally evaluated to prevent any further loss of life and property during future earthquakes.

    Experimental Analysis of the Behavior of Composite Column-Reinforced Concrete Beam Joints
    (Springer Heidelberg, 2021) Tunc, Gokhan; Dakhil, Abdulrrahman; Mertol, Halit Cenan
    This study assesses the seismic performance of steel-reinforced concrete (SRC) composite columns connected to reinforced concrete (RC) beam joints, and their ability to dissipate seismic energy through inelastic deformations. In this article, experimental aspects regarding the seismic performance of high-ductility and low-ductility steel-concrete composite frame were investigated. The principle design parameter in this study was ductility, which is considered a conceptual framework in Efficiency-Based Seismic Engineering. Thus, attention was focused on assuring various ductility ranges of joints obtained through a detailed study of the Turkish Earthquake Code (TEC 18) [Ministry of Public Works and Housing.: Turkiye Bina Deprem Yonetmeligi (Turkey's Earthquake Code for Buildings). Official Gazette (2018) (in Turkish).]. After identifying deficiencies and the energy dissipation capacity in the newly proposed joints, two half-scaled frames with specific ductility-related designs were constructed, instrumented, tested, and analyzed. The specimens were tested under displacement-controlled lateral cyclic loading that incorporated constant axial loading to create cyclic tension and compression facets across the joint areas. The test results proved that the SRC column-RC beam frames employing an extra column reinforcement ratio exhibit slightly better seismic performance. Due to the presence of structural steel, the shear failure of the joint was effectively prevented, even after the formation of the plastic hinge on the interface of the beam. During the testing, the column rebars, to some extent, made a minor contribution to the joint strength of the specimen compared to the structural steel that absorbed almost all of the load applied to the frame.

    Finite Element Analysis of Frames With Reinforced Concrete Encased Steel Composite Columns
    (Mdpi, 2022) Tunc, Gokhan; Othman, Mohammed Moatasem; Mertol, Halit Cenan
    Structural frame systems that consists of concrete-encased-steel-embedded composite columns and reinforced concrete beams are typically used in mid-rise to tall buildings. In order to understand their overall structural behavior, a total of 12 frame models with high and low ductility features were constructed and analyzed using LS-DYNA software. Two of these models were validated using the results of previously tested frames. The remaining 10 models were studied to predict the behavior of frames with varying concrete strengths, reinforcement configurations, and structural steel sections under vertical and lateral loads. The results were investigated in terms of cracks and failure patterns, load-deflection relationships, energy dissipation, and stiffness degradation. The analytical results indicated that the high ductile frame models showed slightly better lateral load carrying performances compared to low ductility frame models. Moreover, the analytical studies demonstrated that the existence of structural steel in a column, regardless of its cross-sectional shape, was the most important parameter in improving the lateral load carrying capacity of a frame.

    A Close Examination of Ankara's Reinforced Concrete Buildings Designed and Constructed Between 1923 and 1938
    (Mdpi, 2023) Tunc, Gokhan; Tunc, Tanfer Emin
    The Republic of Turkey was established in 1923 out of the remains of the Ottoman Empire. Between 1923 and 1938, the Turkish republic underwent fifteen years of rapid expansion and growth, with Ankara as its new capital and Mustafa Kemal Ataturk (1881-1938) as its first president. During this period, reinforced concrete (RC) played a significant role in the construction of Ankara's public-use buildings. This study focuses on 57 of these structures, built either partially, or entirely, out of RC. The buildings are classified with respect to their duration, soil properties, foundation types, structural design details, construction types, materials and overall costs. In order to provide a better picture of the time period in which these buildings were designed and constructed, the technical, financial and political aspects of the projects, and the difficulties and challenges involved in their design and construction, are also discussed. Furthermore, this study outlines the impact of foreign engineers, construction workers, firms and the educational system on the development of civil engineering and use of RC in Turkey.

    Transferring Technical Knowledge To Turkey: American Engineers, Scientific Experts, and the Erzincan Earthquake of 1939
    (Royal Society Publishing, 2022) Tunc,T.E.; Tunc,G.
    On 27 December 1939, a 7.8 magnitude earthquake struck Erzincan, Turkey, claiming close to 33 000 lives, and leaving 100 000 injured and 250 000 homeless. World War II was in its initial stages, and the USA was particularly concerned about the vulnerable situation in Turkey, since there was a possibility that it would join forces with Germany, as the Ottoman Empire had done in World War I. Consequently, the Turkish request for information on 'a type of quake resistant concrete construction understood to have been developed in California', resulted in a flurry of correspondence between numerous Turkish and American actors, including the US State Department, which supplied this material with notable attentiveness. As this article will argue, this request not only represents an early critical juncture in the transfer of earthquake engineering knowledge from the USA to Turkey, but also illustrates how diplomacy and engineering can intersect at pivotal points in time. Engineers and other scientific experts strengthened the Turkish-American relationship during this period, thereby laying the foundation of the technical cooperation that would flourish during the Cold War. This watershed moment also resulted in immediate developments in Turkey, such as the development of a comprehensive national disaster management programme, a seismic zone map, and earthquake building codes. © 2021 The Author(s).
