Earthquakes are among natural disasters with significant damage potential; however it is possible to reduce the losses by taking several remedies. Reduction of seismic losses starts with identifying and estimating the expected damage to some accuracy. Since both the design styles and the construction defects exhibit mostly local properties all over the world, damage estimations should be performed at regional levels. Another important issue in disaster mitigation is to determine a robust measure of ground motion intensity parameters. As of now, well-built correlations between shaking intensity and instrumental ground motion parameters are not yet studied in detail for Turkish data. In the first part of this thesis, regional empirical Damage Probability Matrices (DPMs) are formed for Turkey. As the input data, the detailed damage database of the 17 August 1999 Kocaeli earthquake (Mw=7.4) is used. The damage probability matrices are derived for Sakarya, Bolu and Kocaeli, for both reinforced concrete and masonry buildings. Results are compared with previous similar studies and the differences are discussed. After validation with future data, these DPMs can be used in the calculation of earthquake insurance premiums. In the second part of this thesis, two relationships between the felt-intensity and peak ground motion parameters are generated using linear least-squares regression technique. The first one correlates Modified Mercalli Intensity (MMI) to Peak Ground Acceleration (PGA) whereas the latter one does the same for Peak Ground Velocity (PGV). Old damage reports and isoseismal maps are employed for deriving 92 data pairs of MMI, PGA and PGV used in the regression analyses. These local relationships can be used in the future for ShakeMap applications in rapid response and disaster management activities.

Seismic fragilities for non-ductile reinforced concrete frames - Role of aleatoric and epistemic uncertainties Çelik, Ozan Cem (2010-01-01) Seismic fragilities are essential to earthquake loss estimation and performance-based earthquake engineering in regions of high seismicity. Construction practices for frames in regions of moderate seismicity are quite different, and such frames have received less attention in the literature. Fragilities for performance levels identified in recent seismic regulations are developed herein for reinforced concrete frames designed for gravity load in low-seismic regions using probabilistic non-linear finite elem...
A comparative structural and architectural analysis of earthquake resistant design principles applied in reinforced concrete residential buildings in Turkey Özmen, Cengiz; Ünay, Ali İhsan; Department of Building Science in Architecture (2008) The aim of this thesis is to demonstrate that it is possible to design earthquake resistant residential structures without significant compromises in the spatial quality and economic viability of the building. The specific type of structural system that this thesis focuses on is the reinforced concrete skeleton system. The parametric examples and key studies that are used in this research are chosen among applied projects in the city of Bolu. This city is chosen due to its location on the North Anatolian Fa...
Modelling effects of insufficient lap splices on a deficient reinforced concrete frame Lin, Wesley Wei -Chih; Sucuoğlu, Haluk; Binici, Barış; Department of Earthquake Engineering and Engineering Seismology (2013) In order to reduce seismic risk in vulnerable buildings, buildings identified to be at risk should be assessed and strengthened. Performance evaluation of deficient buildings has become a major concern due to devastating earthquakes in the past. In order to justify new provisions in design and assessment codes, experiments and analyses are inherently necessary. In this thesis study, investigations into the behaviour of two deficient reinforced concrete frames built at Middle East Technical University’s Str...
Broadband ground motion simulation within Duzce city (Turkey) Özmen, Ekin; Askan Gündoğan, Ayşegül; Kestel, Sevtap Ayşe; Department of Earthquake Studies (2019) Earthquakes have more hazardous and devastating effects in populated areas. To prevent damage and reduce the risks, broadband records are collected to use in the seismic hazard assessment and engineering seismology. In areas with significant seismic activity and insufficient seismic networks, the simulated ground motions become more important. Broadband ground motion simulations are performed for 12 November 1999 Duzce earthquake. Deterministic simulations are performed for low frequency part and stochastic...
Influence of the shear wall area to floor area ratio on the seismic performance of existing reinforced concrete buildings Günel, Ahmet Orhun; Burak Bakır, Burcu; Department of Civil Engineering (2013) An analytical study is performed to evaluate the influence of shear wall area to floor area ratio on the behavior of existing mid-rise reinforced concrete buildings under earthquake loading. The seismic performance of five existing school buildings with shear wall ratios between 0.00% and 2.50% in both longitudinal and transverse directions and their strengthened counterparts are evaluated. Based on the structural properties of the existing buildings, additional buildings with varying shear wall ratios are ...
