Despite the advanced engineering solutions, earthquakes remain to be one of the causes of casualties and property damage for humankind among natural disasters. To ensure that the essential services are not interrupted after an earthquake, it is crucial for some buildings to remain functional with minimal structural or non-structural damage. These buildings include administrative buildings, law enforcement buildings, fire stations, hospitals, and communication centers. Seismic base isolation systems are frequently used for reducing quake-induced structural and non-structural damage. This thesis mainly focuses on the feasibility of seismic base-isolated structures and determining the maximum feasible number of storeys of the baseisolated structures. Moreover, the effect of the following parameters on the seismic behavior is investigated: (i) isolator parameters, (ii) soil stiffness, (iii) earthquake intensities, and (iv) the aspect ratio of the structure. For this purpose, a comparative assessment is conducted to determine the feasibility of base-isolated structures. The feasibility of the base-isolated structures is assessed by considering the structural and non-structural performance goals.

Evaluation of the accuracy of equivalent linear analysis method for seismic isolated buildings Mutlu, Sezer; Dicleli, Murat; Department of Engineering Sciences (2021-12-1) Earthquakes have been the leading cause of loss of lives and properties since the beginning of human history. After major earthquakes, we see that even the buildings constructed using modern engineering solutions suffer severe damage or even collapse. Seismic base isolation systems are used to minimize earthquake-induced damage. This thesis focuses on evaluating the accuracy of the equivalent linear analysis method in the analysis of seismic base-isolated buildings. In order to do that, certain buildings wi...
Experimental and analytical investigation on the lateral response of ball rubber bearing isolators Del Vecchio, Ciro; Natale, Andrea; Caner, Alp; Di Ludovico, Marco (2022-04-01) © 2022 Elsevier LtdRecent earthquakes demonstrated that modern seismic design and retrofit of constructions should target damage containment to reduce the direct and indirect economic losses and downtime. In this context, the use of base isolation as seismic protection strategy is becoming popular. A variety of devices is available on the market. Elastomeric and metallic sliding devices are the most common type of isolators. Ball rubber bearings (BRBs) combine the practical use and the low maintenance cost ...
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...
Development of a road map and emergency help and detection system for disaster search and rescue operations Yoncacı, İlker; Çakır, Serhat; Department of Science and Technology Policy Studies (2020) Despite humanity is advanced so much in information and technology, it is still not able to interfere or change natural disasters like earthquakes, volcanic explosions and droughts. Along with natural disasters, caused by immersive improvements made in information technologies, technological disasters are also become a big problem in our societies today. New researches need to be made in order to minimize or completely eliminate the effects of these human-based disasters. There is a common understanding tha...
Comparative study of base isolated systems Türkmen, Fatih; Akyüz, Uğurhan; Department of Civil Engineering (2002) This thesis is mainly concerned with providing brief knowledge about the effects of earthquakes on buildings and their response to earthquake forces. Principles of advanced passive earthquake resistant design techniques are also presented. Next, the use of the most common passive earthquake resistant design technique; i.e., base isolation is described, with its historical background, main principles and usage in the world. In order to evaluate the effectiveness of base isolation, and the performance of base...
