This study firstly presents the recent pan-European strong-motion databank that is updated and extended version of previous pan-European databases. The pertaining metadata is carefully compiled and reappraised. The database meets high standards for being a resource for the pan-European earthquake engineering community. Then, an empirical nonlinear site amplification model, a function of the time-based average of uppermost 30m shear wave velocity profile and peak ground acceleration on rock, is developed. The primary aim of deriving such a model is to use it in ground motion prediction equations (GMPEs). Besides, the evaluation of site factors in the seismic design codes shows that it is also applicable in computing site factors. To this end, an alternative methodology that considers the results of probabilistic seismic hazard analysis and deterministic site models is proposed. Finally, this study generates GMPEs for horizontal and vertical elastic response spectral ordinates for different damping values between 1% to 50%. Rather than direct equations for vertical motion, to obtain consistent horizontal and vertical hazard spectrum, compatible vertical-to-horizontal ratio GMPEs are preferred. Additional damping scaling models to modify horizontal and vertical spectra at other damping ratios are proposed.

Practical tools for ranking and selection of groundmotion prediction equations (GMPEs) for probabilistic seismic hazard assessment and development of a regional GMPE Kale, Özkan; Akkar, Sinan; Danciu, Laurentiu; Department of Civil Engineering (2014) This study starts summarizing the progresses in ground-motion databases and ground-motion models in pan-European region and consequent seismic hazard comparisons conducted for individual local and global predictive models. Then, the study presents the compilation of the Middle East region and Turkish ground-motion databases with principle seismological features to be mainly used in predictive model selection process in these regions. In the following step, using a high standard subset of the Middle East gro...
Turkey - adjusted next generation attenuation models Kargıoğlu, Bahadır; Gülerce, Zeynep; Department of Civil Engineering (2012) The objective of this study is to evaluate the regional differences between the worldwide based NGA-W1 ground motion models and available Turkish strong ground motion dataset and make the required adjustments in the NGA-W1 models. A strong motion dataset using parameters consistent with the NGA ground motion models is developed by including strong motion data from Turkey. Average horizontal component ground motion is computed for response spectral values at all available periods using the GMRotI50 definitio...
Implicit monolithic parallel solution algorithm for seismic analysis of dam-reservoir systems Özmen, Semih; Kurç, Özgür; Department of Civil Engineering (2016) This research mainly focuses on developing a computationally scalable and efficient solution algorithm that can handle linear dynamic analysis of dam-reservoir interaction problem. Lagrangian fluid finite elements are utilized and compressibility and viscosity of the fluid are taken into consideration during the reservoir modeling. In order to provide computational scalability and efficiency, domain decomposition methods implemented with parallel computing approaches such as Finite Element Tearing and Inter...
Improved design procedure for double-ridged waveguides Prakash, VVS; Mittra, R; Kuzuoğlu, Mustafa (2002-11-01) This article presents a novel methodology for designing double-ridged waveguides by numerically optimizing their geometric shape such that they sustain the two prescribed lowest order modes. The field solution to the problem is obtained by using the finite element method. The performance of the microgenetic algorithm and the quasi-Newton methods is studied for carrying out geometry optimization. This generalized formulation is capable of handling inhomogeneous material fillings in the guide, and computation...
Multimodal video database modeling, querying and browsing Durak, N; Yazıcı, Adnan (2005-01-01) In this paper, a multimodal video indexing and retrieval system, MMVIRS, is presented. MMVIRS models the auditory, visual, and textual sources of video collections from a semantic perspective. Besides multimodality, our model is constituted on semantic hierarchies that enable us to access the video from different semantic levels. MMVIRS has been implemented with data annotation, querying and browsing parts. In the annotation part, metadata information and video semantics are extracted in hierarchical ways. ...
