“…Dünyanın pek çok ülkesindeki çağdaşları gibi ülkemizde de tescilli kültür varlığı olan erken betonarme sistemiyle üretilmiş dönem yapılarının tespiti (Borden, 2010), ilk geliştirildiği tarihten bu yana tasarım felsefesi yüz yılı aşmış (Smith, 2001) taşıyıcı sistemin karakteristik özellikleri, uy- 3 Beton ve çeliğin ısıl genleşme katsayıları birbirine oldukça yakın olduğundan birliktelikleri ile meydana gelen betonarme elemanlar yapı malzemesi olarak sorunsuz bir davranış gösterirken, betonun gevrek davranışı ve çekme kuvvetlerine karşı zayıflığı sünek özellik gösteren yüksek çekme mukavemetine sahip çelik donatılarla giderilmekte ve çelik için önemli bir tehdit oluşturan korozyon riskine karşı da beton koruyucu bir bazik ortam sağlamaktadır (Ersoy, 1985).

During the second half of the 19 th century in Europe, to take effect in the Ottoman capital, Istanbul, it was necessary to wait for the beginning of the 20 th century for the important developments in construction technology. Architect Kemaleddin, one of the important names of those years, which can be described as a transition period in terms of construction technology, skillfully benefited from the developing construction technologies in the buildings he designed, built, and produced original works in terms of construction technique as well as in the architectural style. As the first of the series of foundation inns, Vakıf Han I is an attractive work that synthesizes all available building materials and construction techniques of the period with its masonry, early reinforced concrete (Hennebique System), and steel elements. At the beginning of the 20 th century, generally mixed construction techniques were used in such buildings which were built in Eminönü and Galata regions where a rapid urban transformation process was witnessed because of the developing maritime transport and international trade. However, there are not many studies about these buildings which are important documents of the construction techniques of the period, that enlightened the design approaches on how these techniques were used together. To protect the unique character of the buildings and as well as the period, detailed researches are needed to illuminate the construction details as well as building materials, but there are also some difficulties and limitations in conducting on-site research in such building which are usually in use. In this study, Vakif Han I is investigated in terms of new construction technologies in the beginnings of 20 th century. The characterization of the original building techniques used and identification of the structural system are the purpose of the study to help for developing sustainable conservation strategies. Furthermore, the environment in which the building emerged is discussed in terms of developments in construction technologies. The structural design approaches of the period are examined through the original documents and projects obtained from the archive. The construction techniques used in the building are described by tracing the original projects in the building. The original projects of the building have been compared with the existing building by in situ observations. As a result of the comparison of original projects and existing building, it was obtained that, all available building materials and construction techniques of the period such as stone and brick masonry, early reinforced concrete (Hennebique System), and structural steel were used in Vakıf Han I, which reached today by preserving its originality. Moreover, it is determined that traditional masonry work and modern composite structural elements made of reinforced concrete (Hennebique System) and structural steel profiles were used in the construction of the building. The main structural system of the building consists of ston...

“…The first generation of reinforced concrete (RC) building construction appeared at the end of the nineteenth century and ended with the outbreak of World War I (de Courcy, 1987). At that time, RC was governed by commercial patented systems, among which the Hennebique system was the most exploited in many countries (Borden, 2010;Cusack, 1987;Hellebois and Espion, 2010). However, many of the structural analyses conducted to date have ignored the characteristics of old RC material, such as the use of low bond bars, the particular pattern of rebars (bar ends, bent-up rebars) and so on (Bussell, 2001).…”

Reinforced concrete constructions of the first generation (pre-1914) form part of our heritage and therefore should be preserved for future generations. Few experimental studies have been conducted on Hennebique continuous structures to estimate the actual bearing capacity of this reinforced concrete system, which was the most popular in many European countries at the turn of the twentieth century. Important information is therefore often missing for accurate modelling of the behaviour of the structure, although structural assessment is crucial in the reuse of any construction. This paper presents results from three bending tests up to failure, carried out on beams from a narrow-gauge railway viaduct designed by Hennebique and built in Belgium in 1904. They provide better understanding of the mechanisms of failure and reveal the main strengths and weaknesses of the typical Hennebique T-beam. The overlapping length of the rebars at the supports is found to be the crucial aspect, even if a large capacity of ductility is observed. Failure occurred owing to slipping of the upper rebars above the support area. This means that attention should be given to detailing. Consequently, localised structural strengthening with additional reinforcements is probably required when seeking to enhance the lifetime of these old reinforced concrete structures.
