Investigation of hydrodynami demands of tsunamis in inundation zone

Özer, Ceren
This thesis analyzed the new parameter “hydrodynamic demand” representing the damage of tsunami waves on structures and coastlines,maximum positive amplitudes and current velocities occurred during tsunami inundation by using the numerical model TUNAMI-N2. Regular shaped basins were used with two different bottom slopes in analyses in order to understand the behaviour of tsunami wave and investigate the change of important tsunami parameters along different slopes during tsunami inundation. In application, different initial conditions were used for wave profiles such as solitary wave, leading elevation single sinusoidal wave and leading depression sinusoidal wave. Three different initial wave amplitudes were used in order to test the change of distribution of the hydrodynamic demand. The numerical results were compared and discussed with each other and with the results of existing analytical and experimental studies.


Low cycle fatigue effects in the damage caused by the Marmara earthquake of August 17, 1999
Acar, Fikri; Gülkan, Polat; Department of Civil Engineering (2005)
This study mainly addresses the problem of estimating the prior earthquake damage on the response of reinforced concrete structures to future earthquakes. The motivation has arisen from the heavy damages or collapses that occurred in many reinforced concrete structures following two major earthquakes that recently occurred in the Marmara Region, Turkey. The analysis tool employed for this purpose is the package named IDARC2D. Deterioration parameters of IDARC's hysteretic model have been calibrated using a ...
Development of a software for seismic damage estimation : case studies
Küçükçoban, Sezgin; Yakut, Ahmet; Department of Civil Engineering (2004)
The occurrence of two recent major earthquakes, 17 August 1999 Mw = 7.4 Izmit and 12 November 1999 Mw = 7.1 Düzce, in Turkey prompted seismologists and geologists to conduct studies to predict magnitude and location of a potential earthquake that can cause substantial damage in Istanbul. Many scenarios are available about the extent and size of the earthquake. Moreover, studies have recommended rough estimates of risk areas throughout the city to trigger responsible authorities to take precautions to reduce...
Correlation of deformation demands with ground motion intensity
Yılmaz, Hazım; Yakut, Ahmet; Department of Civil Engineering (2007)
A comprehensive study has been carried out to investigate the correlation between deformation demands of frame structures and a number of widely cited ground motion intensity parameters. Nonlinear response history analyses of single-degree-of-freedom (SDOF) and multi-degree-of-freedom (MDOF) models derived from sixteen reinforced concrete frames were carried out under a set of eighty ground motion records. The frames were selected to portray features of typical low-to-mid rise reinforced concrete structures...
Simple models for drift estimates in framed structures during near-field earthquakes
Erdoğan, Burcu; Gülkan, Polat; Department of Civil Engineering (2007)
Maximum interstory drift and the distribution of this drift along the height of the structure are the main causes of structural and nonstructural damage in frame type buildings subjected to earthquake ground motions. Estimation of maximum interstory drift ratio is a good measure of the local response of buildings. Recent earthquakes have revealed the susceptibility of the existing building stock to near-fault ground motions characterized by a large, long-duration velocity pulse. In order to find rational so...
Stochastic strong ground motion simulations on North Anatolian fault zone and central Italy: validation, limitation and sensitivity analyses
Uğurhan, Beliz; Askan Gündoğan, Ayşegül; Department of Civil Engineering (2010)
Assessment of potential ground motions in seismically active regions is essential for purposes of seismic design and analysis. Peak ground motion intensity values and frequency content of seismic excitations are required for reliable seismic design, analysis and retrofitting of structures. In regions of sparse or no strong ground motion records, ground motion simulations provide physics-based synthetic records. These simulations provide not only the earthquake engineering parameters but also give insight in...
