Investigation of wind effects on tall buildings through wind tunnel testing

Kayışoğlu, Bengi
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 analyze the response of such buildings under wind effects, wind tunnel tests are accepted to be the most powerful tool all over the world. In this study, a series of tests were performed in Ankara Wind Tunnel on a model building in the shape of a rectangular prism. For the similitude of flow conditions, passive devices were designed. The response of the model building was measured through a high frequency base balance which was designed specifically for this case study. Through the tests, the effects of turbulence intensity, vortex shedding and wind angle of attack on the response of the building were questioned. Finally, the results were compared with the results of various technical specifications about wind.


Investigation of Wind Effects on Tall Buildings through Wind Tunnel Testing
Kurç, Özgür; Shojaee, S. M. Nima; Uzol, Oğuz (2012-10-01)
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. ...

Valuable cases were presented regarding seismic performance of the shallow mat foundations of building structures in Adapazari, Turkey, during the 17 August 1999 Kocaeli İzmit earthquake. The authors attributed the occurrence of displacements of various forms and levels of the mats essentially to the liquefaction or cyclic softening of the saturated fine surface soils of ML/CL type, which dominated those sites. Subsequently, through contrasting the presumed field liquefaction to the analysis results, they ...
Guidelines for structural health monitoring systems on tall buildings and a case study
Gümüş, Oğuzhan; Çelik, Ozan Cem; Department of Civil Engineering (2021-2-15)
The new Turkish Building Earthquake Code requires real-time monitoring of the structural response of buildings of Earthquake Design Class 1 and 2 that are taller than 105 m. Structural health monitoring (SHM) systems on tall buildings have to comply with the SHM Guidelines by the Disaster and Emergency Management Presidency of Turkey, developed as part of two research projects that were undertaken at METU and Bogazici University. Two tall buildings in Izmir and Istanbul, respectively, were instrumented as c...
Seismic performance assessment of wide beam infill joist block frame structures in Turkey
Karaaslan, Enes; Erberik, Murat Altuğ; Department of Civil Engineering (2015)
Wide-beam frame buildings are prevalent in Turkey since 1980’s due to their advantageous characteristics such as ease of construction, construction speed and cost efficiency. However; according to recent experimental studies, wide beam systems demonstrate poor energy dissipation capacity under earthquake. The capacities of the wide-beams may not fully developed at the beam-column joints. The beam reinforcements that do not anchor to the core area of the columns may not reach their full capacities unless spe...
Performance Based Seismic Evaluation of a 62 Story RC Tower in Istanbul
Budak, Erhan; Sucuoğlu, Haluk (2018-06-18)
A 62-story tall reinforced concrete office building with a free-standing height of 250 m has been designed in Istanbul in accordance with the new Turkish Earthquake Code (TEC, 2017). According to TEC 2017, buildings taller than 70 m and located in the first and second seismic zones are classified as tall buildings and these building shall be designed to meet the special rules based on performance-based seismic design approach. The tall building in Istanbul, having a parallelogram shaped floor plan and reinf...
