This paper describes the analysis of a parameter, "hydrodynamic demand,'' which can be used to represent the potential for tsunami drag force related damage to structures along coastlines. It is derived from the ratio of drag force to hydrostatic force caused by a tsunami on the structure. It varies according to the instantaneous values of the current velocities and flow depths during a tsunami inundation. To examine the effects of a tsunami in the present study, the analyses were performed using the tsunami numerical model in two altered regular-shaped basins having different bottom slopes. The simulations were implemented using a single sinusoidal wave with particular initial conditions, such as leading elevation wave and leading depression wave profiles with different wave periods. Two different initial wave amplitudes were employed to assess the diversity in the distribution of the square of the Froude number Fr(2) along the coastline. The numerical results were compared quantitatively.

Evaluation of Site Response with Alternative Methods: A Case Study for Engineering Implications Sisman, Fatma Nurten; Askan Gündoğan, Ayşegül; Asten, Michael (Springer Science and Business Media LLC, 2018-01-01) In this paper, efficiency of alternative geophysical techniques for site response is evaluated in two sedimentary basins on the North Anatolian Fault Zone. For this purpose, fundamental frequencies of soils and corresponding amplitudes obtained from empirical horizontal-to-vertical spectral ratio curves from microtremors, weak motions and strong motions are compared with results from one-dimensional theoretical transfer functions. Theoretical transfer functions are computed using S-wave velocity profiles de...
Engineering characteristics of the near-field strong motions from the 1999 Kocaeli and Duzce Earthquakes in Turkey Sucuoğlu, Haluk (Springer Science and Business Media LLC, 2002-07-01) The purpose of this paper is to summarize the strong motion data from the nearest stations to the fault ruptures of the August 17, 1999 Kocaeli and November 12, 1999 Duzce earthquakes and to document information that will be significant for its interpretation. Significant engineering characteristics of the near-field strong motions are discussed, with particular emphasis on the site conditions, rupture directivity effects and transverse component orientations relative to the fault. In the course of this stu...
Broadband Ground Motion Simulation Within the City of Düzce (Turkey) and Building Response Simulation Ozmen, Ekin; Karim Zadeh Naghshineh, Shaghayegh; Askan, Aysegul (Springer Science and Business Media LLC, 2020-05-01) In areas with significant seismic activity and insufficient seismic networks, simulated ground motions are required for both seismic hazard and engineering analyses. One important task is evaluating the efficiency of the simulated records in building response estimation. In this study, a hybrid ground motion simulation framework is presented to obtain broadband ground motion time histories of a past major earthquake in Düzce (Turkey). The hybrid ground motion simulation framework presented herein is a combi...
Assessment of Point-Source Stochastic Simulations Using Recently Derived Ground-Motion Prediction Equations Akkar, Dede Sinan; Yenier, Emrah (Seismological Society of America (SSA), 2009-12-01) The simplicity of the point-source stochastic simulation method makes it one of the most appealing tools for the quantification of ground motions for seismic hazard related studies. In this article, we scrutinize the limitations of this technique in terms of fundamental geophysical model parameters. To achieve this objective, we use the estimations of recent Next Generation Attenuation (NGA) and European empirical ground-motion models that are based on global strong-motion databases. The generated synthetic...
Estimating tectonic history through basin simulation-enhanced seismic inversion: geoinfomatics for sedimentary basins Tandon, K; Tuncay, Kağan; Hubbard, K; Comer, J; Ortoleva, P (Oxford University Press (OUP), 2004-01-01) A data assimilation approach is demonstrated whereby seismic inversion is both automated and enhanced using a comprehensive numerical sedimentary basin simulator to study the physics and chemistry of sedimentary basin processes in response to geothermal gradient in much greater detail than previously attempted. The approach not only reduces costs by integrating the basin analysis and seismic inversion activities to understand the sedimentary basin evolution with respect to geodynamic parameters- but the tec...
