Article Citation - WoS: 3Citation - Scopus: 3Engineering the Public-Use Reinforced Concrete Buildings of Ankara During the Early Republic of Turkey, 1923-1938(Pergamon-elsevier Science Ltd, 2022) Tunc, Gokhan; Tunc, Tanfer Emin; Civil EngineeringToday, reinforced concrete (RC) is the most commonly used construction material in Turkey. It first emerged in Europe in the 1850s and was adopted in a number of Late Ottoman period structures, mostly in Istanbul, during the first two decades of the twentieth century. During the Early Turkish Republic (1923-1938), RC appeared in public-use buildings in Ankara, such as the Ethnographic Museum, which was the first in the new capital to feature RC elements, leading the way for many more structures to come. Despite the fact that Turkish and foreign civil engineers faced a series of economic, social, cultural, political, educational and technical challenges during the transition from masonry and timber construction to RC, its adoption was facilitated by the fact that as a European building technology, it became symbolically important to the new republic. Equated with modernity, RC would allow its capital, Ankara, to construct an identity that would contrast with Istanbul, the capital of the Ottoman Empire. This transition would also be catalyzed by the rise of a professional class of Turkish civil engineers who deployed RC to reinforce their authority as trained specialists and agents of modernization.Article Citation - WoS: 4A 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; Civil EngineeringIn 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.Article Public Policy and the Turkish Construction Sector(2015) Tunç, Gökhan; Civil EngineeringThis article discusses public policy as it has been adapted to the Turkish construction sector. The problems related to current policy are discussed along with their remedies. The power struggle that exists among the entities representing the government and the private sector are investigated. The lack of trust that exists in the construction sector is also evaluated as a key roadblock to quality management. In the recommendations section, solutions to such problems are proposed. Overall, the intent of this article is to elevate the quality of Turkey’s construction sector by eliminating and/or rehabilitating existing public policy.Article Türkiye’de ve Dünyada Yüksek Binalar(2022) Tunç, Gökhan; Civil EngineeringYüksek binalar, gelişen inşaat teknolojisi ve yapı tasarımı yöntemleri nedeni ile özellikle büyük şehirlerde yaygınlaşmaktadır.

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.Article Citation - WoS: 3Citation - Scopus: 6Experimental Analysis of the Behavior of Composite Column-Reinforced Concrete Beam Joints(Springer Heidelberg, 2021) Tunc, Gokhan; Dakhil, Abdulrrahman; Mertol, Halit Cenan; Civil EngineeringThis 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.Article Citation - WoS: 1Citation - Scopus: 1A Close Examination of Ankara's Reinforced Concrete Buildings Designed and Constructed Between 1923 and 1938(Mdpi, 2023) Tunc, Gokhan; Tunc, Tanfer Emin; Civil EngineeringThe 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.Article İNŞAAT MÜHENDİSLİĞİ EĞİTİMİNDE GÜZEL YAZI YAZMA SANATI VE ÇİZİM BECERİLERİ(Yapı Dergisi, 2017) Tunç, Gökhan; Civil EngineeringMühendis kelimesi Arapça kökenli bir kelime olup hendese yani geometri bilen kişi olarak tariflenir.

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).
