GIS Based tsunami inundation maps; case studies from Mediterranean

Dilmen, Derya Itır
In this thesis, detailed tsunami numerical modeling study was applied to the selected case studies, Fethiye town (Turkey) and Kiparissia-Zakintos-Pylos (Greece) in Mediterranean, using rupture-specific tsunami sources which can generate tsunamis in Mediterranean. As a first step of the study, the general database of Fethiye and Kiparissia-Zakintos-Pylos were integrated to GIS-based environment to organize, analyze and display reliable data from different sources. Secondly, for each earthquake scenario, the tsunami propagation and coastal amplifications were computed by TUNAMI N3 to evaluate the coastal amplifications of tsunamis and understand the tsunami propagation for the cases. As the final step, a study of inundation areas of probable tsunamis in these regions was performed. Available results were used to understand the effects of tsunamis and assist in developing mitigation strategies. Methods and results were presented and discussed.


Vertical ground motion influence on seismically isolated & unisolated bridges
Rehanoğulları, Naim Eser; Akyüz, Uğurhan; Department of Civil Engineering (2010)
In this study influences of vertical ground motion on seismically isolated bridges were investigated for seven different earthquake data. One assessment of bearing effect involves the calculation of vertical earthquake load on the seismically isolated bridges. This paper investigates the influence of vertical earthquake excitation on the response of briefly steel girder composite bridges (SCB) with and without seismic isolation through specifically selected earthquakes. In detail, the bridge is composed of ...
Main seismological features of recently compiled Turkish strong motion database
Erdoğan, Özgür; Akkar, Sinan D.; Department of Civil Engineering (2008)
In this thesis it is aimed to compile the Turkish strong-motion database for its efficient use in earthquake engineering and strong-motion seismology related studies. Within this context, the Turkish strong-motion database is homogenized in terms of basic earthquake source parameters (e.g. magnitude, style-of-faulting) as well as site classes and different source-to-site distance metrics. As part of this objective, empirical relationships for different magnitude scales are presented for further harmonizatio...
Performance of a precast concrete beam-to-beam connection subject to reversed cyclic loading
Korkmaz, HH; Tankut, T (Elsevier BV, 2005-08-01)
This study was performed as one phase of an extensive research program focusing on the seismic behaviour of precast connections carried out in Middle East Technical University. The primary objective of the research program was to observe and investigate the seismic behaviour of the connection detail proposed by the collaborating company and the specimens with improved details, in order to develop a 11 moment resisting precast concrete beam-to-beam connection". In this study, six beam-beam connection subasse...
Energy based seismic performance assessment of reinforced concrete columns
Acun, Bora; Sucuoğlu, Haluk; Department of Civil Engineering (2010)
Severe seismic events in urban regions during the last two decades revealed that the structures constructed before the development of modern seismic codes are the most vulnerable to earthquakes. Sub-standard reinforced concrete buildings constitute an important part of this highly vulnerable urban building stock. There is urgent need for the development and improvement of methods for seismic performance assessment of existing reinforced concrete structures. As an alternative to current conventional force-ba...
Stabilization of expansive soils using waste marble dust
Başer, Onur; Çokça, Erdal; Department of Civil Engineering (2009)
Expansive soils occurring in arid and semi-arid climate regions of the world cause serious problems on civil engineering structures. Such soils swell when given an access to water and shrink when they dry out. Several attempts are being made to control the swell-shrink behavior of these soils. Soil stabilization using chemical admixtures is the oldest and most widespread method of ground improvement. In this study, waste limestone dust and waste dolomitic marble dust, by-products of marble industry, were us...
