Evaluation of the accuracy of equivalent linear analysis method for seismic isolated buildings

Mutlu, Sezer
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 with different story numbers, widths, and isolator parameters were analyzed by using a set of ground motions selected for different soil properties, and results were compared with the results obtained from the equivalent linear analysis method.


Effect of the number of stories and aspect ratio on the seismic performance of base-isolated buildings

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 freq...
Advancement of Satellite Rainfall Applications for Hydrologic Modeling with Emphasis on Flood Monitoring (FLOODSAT)
Yılmaz, Koray Kamil(2014-3-31)
"Floods are the most widespread and frequent natural disaster responsible for significant loss of lives and property each year. The European Environmental Agency estimated that floods in Europe between 1998 and 2002 caused about 700 deaths, the displacement of about half a million people and at least 25 billion Euros in insured economic losses. As such, one of the four priority areas in FP7 has been identified as triggering factors and forecasting and mitigation strategies for natural hazards. Flood early ...
Probabilistic seismic hazard assessment for earthquake induced landslides
Balal, Onur; Gülerce, Zeynep; Department of Civil Engineering (2013)
Earthquake-induced slope instability is one of the major sources of earthquake hazards in near fault regions. Simplified tools, such as Newmark’s Sliding Block (NSB) Analysis are widely used to represent the stability of a slope under earthquake shaking. The outcome of this analogy is the slope displacement where larger displacement values indicate higher seismic slope instability risk. Recent studies in the literature propose empirical models between the slope displacement and single or multiple ground mot...
Factors related to psychological resilience among survivors of the earthquakes in Van, Turkey
İkizer, Gözde; Karancı, Ayşe Nuray; Department of Psychology (2014)
Exposure to natural disasters is common, with millions of people affected annually. Traumatic events including disasters may result in a wide range of psychological consequences in adults. They may evoke negative outcomes in exposed individuals including posttraumatic stress (PTS) reactions. However, in recent years, the field of trauma studies has fuelled interest in positive changes following adversity including growth and resilience. The present study aimed to investigate psychological resilience in the ...
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...
