This study focuses on the evaluation of seismic safety of unreinforced masonry buildings in Turkey by using fragility curves generated for two behavior modes of load bearing walls: in-plane and out-of-plane. During generation of fragility curves, a force-based approach has been used. There exist two limit states in terms of base shear strength for in-plane behavior mode and flexural strength for out-of-plane behavior mode. To assess the seismic vulnerability of unreinforced masonry buildings in Turkey, fragility curves generated for in-plane behavior were verified by the observed damage during the 1995 Dinar (Turkey) earthquake and fragility curves generated for out-of-plane behavior were verified by the observed damage during the 2010 ElazA +/- AY (Turkey) earthquake. The verification results reveal that the proposed fragility-based procedure can provide an alternative for the seismic safety evaluation of unreinforced masonry buildings in Turkey. Using this procedure, it becomes possible to investigate a large population of masonry buildings located in regions of high seismic risk in a short period of time. The obtained results are valuable in the sense that they can be used as a database during the development of strategies for pre-earthquake planning and risk mitigation for earthquake prone regions of Turkey.

An approximate procedure for estimating the member demands in mid-rise reinforced concrete buildings Akpinar, Ugur; Binici, Barış; Yakut, Ahmet; Tuncay, Kağan (Springer Science and Business Media LLC, 2020-01-01) Seismic assessment of mid-rise reinforced concrete buildings is important for urban seismic risk reduction. Nonlinear time history analysis is the state-of-the-art analysis tool for this purpose. However, the number of such buildings may reach to several tens of thousands in metropolitan cities of earthquake prone countries. This necessitates faster yet sufficiently accurate assessment methods to mitigate the seismic risk. In this study, a simple and efficient approach is developed and validated for the ass...
Effect of Shear Wall Area to Floor Area Ratio on the Seismic Behavior of Reinforced Concrete Buildings Burak Bakır, Burcu (American Society of Civil Engineers (ASCE), 2013-11-01) An analytical study is performed to evaluate the effect of shear wall area to floor area ratio on the seismic behavior of midrise RC structures. For this purpose, 24 midrise building models that have five and eight stories and shear wall ratios ranging between 0.51 and 2.17% in both directions are generated. Then, the behavior of these building models under earthquake loading is examined by carrying out nonlinear time history analyses. In the analyses, seven different ground motion records are applied to th...
Vulnerability of Turkish low-rise and mid-rise reinforced concrete frame structures Ay, Bekir Özer; Erberik, Murat Altuğ (Informa UK Limited, 2008-01-01) In this study, seismic safety of low-rise and mid-rise structures, which constitute approximately 75% of the total building stock in Turkey, is investigated by generating fragility curves. The scope is 3, 5, 7, and 9-story reinforced concrete moment resisting frame structures. The uncertainties in material variability and the specific characteristics of construction practice in Turkey are taken into account in the formation of structural simulations. Two-dimensional analytical models are constructed accordi...
Importance of Degrading Behavior for Seismic Performance Evaluation of Simple Structural Systems Erberik, Murat Altuğ (Informa UK Limited, 2011-01-01) This study focuses on effect of degradation characteristics on seismic performance of simple structural systems. Equivalent single degree of freedom systems are used for which the structural characteristics are taken from existing reinforced concrete (RC) frame buildings. Simulation of degrading behavior is achieved by considering actual experimental data. To obtain the seismic response of degrading structural systems, two different approaches are used: inelastic spectral analysis and fragility analysis. Ac...
Effect of Foundation Soil Stiffness on the Seismic Performance of Integral Bridges Dicleli, Murat (Informa UK Limited, 2011-05-01) In this study, the effect of foundation soil stiffness on the seismic performance of integral bridges (IBs) is investigated. For this purpose, nonlinear structural models of a two-span TB with four different foundation soil stiffness types (loose, medium, medium-dense and dense sands) are built. In the nonlinear structural models, nonlinear soil structure interaction including free-field effects is considered. Then, the nonlinear time history analyses of the TB models are conducted using a set of ground mot...
