There has been significant increase in tall building construction in Turkey in the last decade. As the height of building increase, wind effects become more pronounced. Wind can interact with flexible buildings and can significantly magnify the wind loads and wind induced oscillations. Wind tunnel tests have been widely utilized for estimating the wind effects on buildings. In order to perform a successful test, however, flow conditions inside the tunnel must represent the actual conditions rather closely. In this study, passive devices were designed to create wind profiles defined in wind codes inside Ankara Wind Tunnel that has a short test section. The performance of the designed passive devices was investigated through numerical and experimental studies. Then, wind effects on a rectangular shaped building were examined with high frequency base balance technique. The effect of turbulence intensity, vortex shedding and wind attack angle on wind loads were questioned. Finally base moments calculated from test results were compared with the results of various wind codes.

Investigation of wind effects on tall buildings through wind tunnel testing Kayışoğlu, Bengi; Kurç, Özgür; Department of Civil Engineering (2011) In recent years, especially in the crowded city-centers where land prizes have become extremely high, tall buildings with more than 30 floors have started to be designed and constructed in Turkey. On the other hand, the technical improvements have provided the opportunity of design and construction of more slender structures which are influenced by the wind actions more. If the building is flexible, wind can interact with it so the wind induced oscillations can be significantly magnified. In order to analyz...
Hydroelectric power potential and its use in Turkey Taşdemiroğlu, Erol (Elsevier BV, 1988-7) Hydroelectric development in Turkey is briefly reviewed. The results of estimates of gross and economically exploitable hydroelectric power potentials are compared. Dam sites and their order for construction are identified. Present and future developments in the power sector are analyzed and projections are given for electricity consumption and production to the year 2010. Hydraulic, thermal and nuclear contributions to total electricity generation are discussed. Finally, problems associated with hydroelect...
Comparative study of commercial structural analysis programs in view of seismic assessment procedures in Turkish earthquake code 2007 Yıldırım, Suat; Akyüz, Uğurhan; Yakut, Ahmet; Department of Civil Engineering (2011) In Turkey, most of the existing buildings have been designed according to Turkish Earthquake codes of 1975 and 1997. It is a well known fact that, poor material quality, poor design, poor control on site and inadequate workmanship makes existing buildings vulnerable to earthquake. In addition, change in function of buildings becomes another problem. These problems increase the importance of assessment of existing buildings. For this purpose, a new chapter has been added to the new code and assessment method...
Analysis of a multi-story reinforced concrete residential building damaged under its self-weight Korkmaz, Hasan Husnu; Yakut, Ahmet; Bayraktar, Atilla (Elsevier BV, 2019-04-01) Reinforced concrete framed residential buildings are remarkably common in Turkey. Observations after recent earthquakes revealed that a great portion of the present building stock has inadequate seismic resistance. Moreover, collapses of several multi-story reinforced concrete buildings under their self-weight have also been observed despite any dynamic activity. The tragic example of the collapse of the "Zumrut" residential building under its self-weight in 2004 and the death of its 93 occupants have highl...
Performance-based seismic rehabilitation of damaged reinforced concrete buildings Sucuoğlu, Haluk; Gunay, MS (American Society of Civil Engineers (ASCE), 2004-10-01) A building stock consisting of 130 medium-rise reinforced concrete buildings were damaged moderately during the recent earthquakes in Turkey. These buildings were rehabilitated by using simple, cost-effective methods where the newly added shear walls comprised the primary lateral load resisting system. In the presented study, different seismic performance evaluation procedures are tested first on the samples of damaged buildings for predicting their observed performances. Then the expected performances of t...
