On October 23, 2011, a destructive earthquake of Mw=7.1 occurred in Eastern Turkey. The event occurred on a previously unknown fault with a thrust mechanism and resulted in 604 deaths and major structural damage to the buildings. The highways at the Van earthquake zone were open to service of rescue operations, aid trucks, and regular traffic immediately after the devastating event. As a success story, the bridges closer to the fault line than the towns of Van and Erci were observed to have minimal damage, such as minor support movements and cracks at the shear keys. Among the 14 highway bridges in the region evaluated by the authors, only two adjacent bridges, Bendimahi-II, had minor structural cracking along the column height. As expected, the bridges of concern were observed to perform in the essentially elastic state. The main focus of this study was to evaluate the seismic bridge design practice in Turkey, which resulted in a successful seismic performance of the earthquake-zone bridges. As an illustrative example, Bendimahi-II bridge, the closest one to the fault line, was studied through an analytical investigation.

Damage in Reinforced Concrete Buildings during the 2011 Van Turkey Earthquakes Baran, Eray; GÜNEŞ, BURCU (American Society of Civil Engineers (ASCE), 2014-06-01) Two major earthquakes with magnitudes Mw=7.2 (ML=6.7) and ML=5.6 occurred in eastern Turkey on October 23 and November 19, 2011. The maximum measured peak ground accelerations for the two ground motions were 0.18g and 0.25g, respectively. The earthquakes resulted in various levels of damage to RC moment-resisting frame buildings ranging from minor cracking in brick partition walls to total collapse. This paper summarizes the field observations of the Atilim University Reconnaissance Team carried out in the ...
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...
Developing an innovative architectural and structural solution for seismic strengthening of reinforced concrete residential buildings Toker, Saadet; Ünay, Ali İhsan; Department of Architecture (2004) The recent earthquakes in Turkey have shown the poor seismic performance of reinforced concrete. This led to widespread utilization of several strengthening methods, each of which is convenient in different aspects. However, what is required to apply any of these methods is to evacuate the building in question since the interruptions are mostly within the building and to the structural members. This study proposes a method for external strengthening of typical five storey reinforced concrete buildings that ...
Evaluation study on the instrumentation system of cindere dam Yanmaz, Ali Melih (American Society of Civil Engineers (ASCE), 2009-11-26) The first hardfill dam in Turkey, Cindere Dam, has recently been constructed and a number of instruments have been installed. The aim of this study is to review the capability of the current instrumentation system and to observe the feasibility of possible alternative measurement systems. To this end, the current instrumentation system has been evaluated as a whole with reference to the parameters measured, instruments, and data acquisition system. Afterward, an alternative instrumentation system was develo...
Re-examination of damage distribution in Adapazari: Geotechnical considerations Bakır, Bahadır Sadık; Yakut, Ahmet (Elsevier BV, 2005-06-01) The role of ground conditions in damage distribution patterns of buildings in the city of Adapazari during the 17 August 1999 Izmit (Kocaeli) earthquake (M-w 7.4) is investigated. Damage was concentrated in the central districts of the city over the alluvial basin where four to seven-story reinforced concrete buildings were most adversely affected. Two distinct and mutually exclusive modes of building damage were observed on the alluvium: structural system failures due to strong ground shaking, and foundati...
