Turkey has many active faults which have the potential to generate large earthquakes. Recent earthquakes showed that the buildings in Turkey are not well designed and vulnerable to earthquakes. Previous studies on the subject showed that many structures in Turkey need to be strengthened before the next major earthquake to minimize property loss and casualties. A number of fast and approximate (mostly empirical) methods have been developed in the past to process large building stock. However, there are some important and special structures that do not fit with the general building stock and needs special consideration (e.g., disaster management center, governmental buildings, hospitals, tall structures, etc.). This study targets to evaluate those important and special structures in a detailed, fast, and correct manner. The developed software, which constitutes an important part of this study, does process the building information several times to determine member-based importance factors. The vulnerability index of the building will be determined using the importance of each load-carrying member and how much each member is forced with respect to its capacity. In order to augment user perception, a functional graphical user-interface is designed. Software is equipped with modules that generate input files for SAP2000 analysis program, conduct dynamic and static analysis automatically, and postprocess the generated analysis results which enable the engineer to make a decision on the vulnerability of the structure. Program is written in C++, using object-oriented programming technique. The main difference between this and similar studies is the generator program which automatically generates 3D-FE models and post-processes nonlinear analysis results for an effective decision

Assessment of tsunami resilience of Haydarpasa Port in the Sea of Marmara by high-resolution numerical modeling AYTÖRE, Betul; Yalçıner, Ahmet Cevdet; Zaytsev, Andrey; ÇANKAYA, Zeynep Ceren; Süzen, Mehmet Lütfi (Springer Science and Business Media LLC, 2016-08-02) Turkey is highly prone to earthquakes because of active fault zones in the region. The Marmara region located at the western extension of the North Anatolian Fault Zone (NAFZ) is one of the most tectonically active zones in Turkey. Numerous catastrophic events such as earthquakes or earthquake/landslide-induced tsunamis have occurred in the Marmara Sea basin. According to studies on the past tsunami records, the Marmara coasts have been hit by 35 different tsunami events in the last 2000 years. The recent o...
Neotectonics of Turkey - a synthesis Bozkurt, Erdin (2001-01-01) Turkey forms one of the most actively deforming regions in the world and has a long history of devastating earthquakes. The better understanding of its neotectonic features and active tectonics would provide insight, not only for the country but also for the entire Eastern Mediterranean region. Active tectonics of Turkey is the manifestation of collisional intracontinental convergence- and tectonic escape-related deformation since the Early Pliocene (similar to5 Ma). Three major structures govern the neotec...
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 ...
Field Investigations and a Tsunami Modeling for the 1766 Marmara Sea Earthquake Turkey Vardar, Hande Aykut; Altınok, Yıldız; Alpar, Şaban Bedri; Ünlü, Vesile Selma; Yalçıner, Ahmet Cevdet (null; 2016-12-16) Turkey is located on one of the world's most hazardous earthquake zones. The northern branch of the North Anatolian fault beneath the Sea of Marmara, where the population is most concentrated, is the most active fault branch at least since late Pliocene. The Sea of Marmara region has been affected by many large tsunamigenic earthquakes; the most destructive ones are 549, 553, 557, 740, 989, 1332, 1343, 1509, 1766, 1894, 1912 and 1999 events. In order to understand and determine the tsunami potential and the...
Probabilistic earthquake hazard assessment for Ankara and its environs Ozmen, Bulent; Başbuğ Erkan, Berna Burçak (The Scientific and Technological Research Council of Turkey, 2014-01-01) The capital and the second largest city of Turkey, Ankara, is generally considered to be safe in terms of seismic activities and earthquake hazard. However, recent studies and earthquakes experienced in the region showed that Ankara is not indeed seismically safe. As the number of studies on Ankara's seismic hazard increases, the number of scientists who claim that the earthquake hazard in Ankara is higher than expected also increases. However, to date no detailed analysis has been undertaken as to the eart...
