Performance Based Seismic Evaluation of a 62 Story RC Tower in Istanbul

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 reinforced concrete core wall-peripheral frame system will be one of the tallest buildings in Europe. In this study, a comprehensive description of the structural system of the building is given. Then the design criteria for seismic and wind actions and the analytical models prepared for different performance levels are explained. Finally, the results obtained for the Immediate Occupancy performance under 43-year earthquake and Life Safety performance level under the 2475-year earthquake are presented and discussed. In this sense, this study presents the first real case implementation of the new Turkish Earthquake Code for the design of tall buildings in severe seismic zones.

Performance based seismic design of reinforced concrete tall buildings
Budak, Erhan; Sucuoğlu, Haluk (null; 2017-01-13)
The need for tall buildings are steadily increasing all over the world, in parallel to the need for new living spaces in large cities. Improvements in technological equipment, material science and analysis methods have opened opportunities to construct new life areas by rising along the vertical direction instead of horizontal. Unlike regular buildings, tall buildings are peculiar due to their specific architectural properties and building configurations. On the other hand, most of these buildings are locat...
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 vulnerability assessment using regional empirical data
Yakut, Ahmet; Yucemen, M. Semih (2006-08-01)
This article presents a procedure developed for the seismic performance assessment of low- to mid-rise reinforced concrete buildings in Turkey. The past performance of reinforced concrete buildings during major earthquakes have been compiled and analysed comprehensively using statistical procedures in order to study the empirical correlation between the significant damage inducing parameters and the observed damage. A damage database of nearly 500 representative buildings experiencing the 1999 Kocaeli and D...
Seismic risk prioritization of residential buildings in Istanbul
Yakut, Ahmet; Sucuoğlu, Haluk (2012-09-01)
A large scale seismic risk prioritization study was conducted for medium-rise, gravity-designed reinforced concrete residential buildings in Istanbul. The implemented procedure was based on evaluating selected building parameters that could be easily observed or measured during a systematic sidewalk survey. The survey was actually conducted on approximately 100,000 buildings in the six subprovinces of Istanbul over the period 20042009 by a large team of trained surveyors. The collected data were processed t...
Calibration of Turkish LRFD bridge design code for slab on steel plate girders
Koç, A. Fatih; Caner, Alp; Yücemen, Mehmet Semih (IOS Press, 2013-01-01)
In Turkish design practice, slab on steel composite I-girder bridges have been designed to span between 50 and 80 meters. To date, modified versions of the AASHTOLFD (Load Factor Design) or ASD (Allowable Stress Design) requirements are adapted in Turkey. The recent switch of the U.S. bridge codes to Load Resistance Factor Design (LRFD) method also necessitates the calibration of the Turkish LRFD design code that is under development. In this on-going research, it has been determined that the current Turkis...
