Large earthquakes are known to have significant damage potential in urban regions. Recently all over the world, efforts are made toward reduction of future probable damages. The first step in damage mitigation is the estimation of expected damage levels in buildings that are subjected to earthquakes with different intensities. Due to the inherent uncertainties involved in the analyses, estimation of seismic damage rates must be handled within a probabilistic framework. To assess the damage rates under different shaking levels, “seismic damage” needs to be quantified and measured in a standard manner. The most common approach to quantify seismic damage rates is to perform fragility analyses. Fragility is defined as the probability of a system reaching a limit state as a function of seismic intensity levels...

Relationships between felt intensity and instrumental ground motion parameters for Turkey Bilal, Mustafa; Askan Gündoğan, Ayşegül; Department of Civil Engineering (2013) 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 m...
Strengthening of reinforced concrete frames by using steel bracings Ağar, Mehmet; Polat, Mustafa Uğur; Department of Civil Engineering (2008) Structures in high seismic risk areas may be susceptible to severe damage in a major earthquake. Structures designed to meet older code requirements may be at even greater risk. When these structures are evaluated with respect to current code criteria, it is observed that they lack of lateral strength and/or ductility. Since safety and economic considerations are major problems, these structures become viable candidates for retrofit and seismic strengthening. For the variety of structures and possible defic...
An Interdisciplinary Approach for Regional Seismic Damage Estimation Askan Gündoğan, Ayşegül; Erberik, Murat Altuğ; Karim Zadeh Naghshineh, Shaghayegh; Yakut, Ahmet (2017-01-09) In order to mitigate seismic risk in urban regions, the first task is to identify potential seismic losses in future earthquakes. Seismic loss estimation is an interdisciplinary framework including a wide range of contributions from geophysical and earthquake engineers, physical and economic planners to insurance companies. In this study, a moderate size city in Turkey, namely Erzincan, is modeled completely from geophysical attributes to the built environment. Erzincan city is on the eastern part of the No...
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...
A screening procedure for seismic risk assessment in urban building stocks Sucuoğlu, Haluk; Yakut, Ahmet (SAGE Publications, 2007-05-01) An effective step for seismic risk mitigation in large urban areas under high seismic risk is to identify the most vulnerable buildings that may sustain significant damage during a future earthquake. Once they are identified properly, existing seismic risks may be reduced either by retrofitting such buildings, or by replacing them with new buildings in view of a particular risk-mitigation planning strategy. A fast and simple seismic risk-assessment procedure for vulnerable urban building stocks is proposed ...
