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 to calculate a safety score for each building, which is in turn used for ranking the surveyed buildings with respect to their expected seismic performance under the calculated ground motion intensities produced for a scenario earthquake of M7.5 along the Marmara Sea Fault. The basic objective of this laborious study was to identify the buildings that would be likely to sustain severe damage or suffer collapse during the expected Istanbul earthquake. Accordingly, a rational risk reduction planning can be conducted for minimizing the life and property losses. This paper presents the methodology, results of field surveys and risks evaluated in 100,000 buildings. As a result, 52,000 buildings have been classified as high risk, that is, expected to sustain severe damage or collapse during the scenario event. Copyright (C) 2012 John Wiley & Sons, Ltd.

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...
COLLAPSE FRAGILITY ANALYSIS OF REINFORCED CONCRETE TALL BUILDINGS Budak, Erhan; Çelik, Ozan Cem; Sucuoğlu, Haluk; Department of Civil Engineering (2022-9-02) Seismic performance of a 253 m tall reinforced concrete core wall building in Istanbul, designed according to performance-based seismic design principles, was assessed to determine the response parameters that control the serviceability, safety and collapse performance limit states. An ambient vibration test of the building was performed to identify its dynamic properties, including the damping properties for service loads. A three- dimensional linear elastic finite element structural model of the building ...
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...
Performance Assessment of Turkish Residential Buildings for Seismic Damage and Loss Estimation Un, Elif M.; Erberik, Murat Altuğ; Askan Gündoğan, Ayşegül (2015-04-01) This study aims to present an integrated method in a probabilistic manner for seismic performance assessment of Turkish residential buildings, which can be used as a tool to estimate earthquake losses due to structural damage. In particular, the objective is to determine the performances of different types of residential buildings for predicting the potential seismic loss in terms of casualties (death toll) for a highly populated city in northwestern Turkey. The main phases of this study are seismic hazard,...
Commonly encountered seismic design faults due to the architectural design of residential buildings in Turkey Özmen, Cengiz; Ünay, Ali İhsan (Elsevier BV, 2007-3) The 17 August 1999 and 12 November 1999 earthquakes in Western Anatolia provided undesirable field evidence that most of the low story residential reinforced concrete buildings have very poor earthquake resistance. Architectural design faults negatively affect the structural behavior of buildings. In Turkey, earthquake-resistant design is considered to be exclusively within the field of responsibility of structural engineers. As a result, architects and especially students of architecture are not well infor...
