A probabilistic model for the evaluation of relaibility of lifeline networks under seismic hazard.

A GIS-based software for lifeline reliability analysis under seismic hazard Kestel, Sevtap Ayşe; ODUNCUOĞLU, Lütfi (2012-05-01) Lifelines are vital networks, and it is important that those networks are still functional after major natural disasters such as earthquakes. Assessing reliability of lifelines requires spatial analysis of lifelines with respect to a given earthquake hazard map. In this paper, a GIS-based software for the spatial assessment of lifeline reliability which is developed by using GeoTools environment is presented. The developed GIS-based software imports seismic hazard and lifeline network layers and then create...
A Model based guidance and vulnerability assessment approach for facilities under the threat of multi-hazard emergiencies Ayhan, Murat; Ayhan, Murat; Birgönül, Mustafa Talat; Department of Civil Engineering (2012) Disasters (e.g. earthquakes) and emergencies (e.g. fire) threaten the safety of occupants in the buildings and cause injuries and mortalities. These harmful effects are even more dangerous when secondary hazards (e.g. post-earthquake fires) emerge and it is commonly observed that the disasters/emergencies trigger secondary hazards.An effective indoor emergency guidance and navigation approach for occupants and first responders can decrease the number of injuries and mortalities during building emergencies b...
A Methodology for real-time sensor-based blockage assessment of building structures during earthquakes Ergin, Tuluhan; Erberik, Murat Altuğ; Kurç, Özgür; Department of Civil Engineering (2013) During and after earthquakes, occupants inside a damaged building should be evacuated rapidly and safely whereas related units outside the buildings (e.g. first responders) should know the current condition of the building. Obviously, this information should be as accurate as possible and accessed timely in order to speed up the evacuation. Unfortunately, absence of such information during evacuation and emergency response operations results in increased number of casualties. Hence, there arises a need for ...
An approach for seismic damage assessment of residential buildings / Demirci, Ceren; Erberik, Murat Altuğ; Askan Gündoğan, Ayşegül; Department of Civil Engineering (2014) For developing countries in earthquake-prone regions, two main issues in seismic damage estimation are identification of seismic hazard in the region of interest and up-to-date information of the existing building stock. This study proposes an approach to handle these key issues and to obtain reliable measures for regional seismic damage estimation. The approach makes use of the basic structural information for different types of construction. This information can be readily available or may have been obtai...
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...
