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 by improving the evacuation process and response operations. For this reason, this research will propose a model-based guidance and vulnerability assessment approach for facilities that are under the threat of multi-hazard emergencies. The approach can be used to guide occupants from the facility affected by disasters/emergencies to safer zones and to direct the first responders by supplying them necessary building related information such as identified vulnerable locations in the indoor environments. An integrated utilization of Building Information Modeling tools, sensors, shortest path algorithms, and vulnerability assessment algorithms is proposed for the system in this research. The research steps of this thesis include (1) determination of requirements of an indoor navigation during emergency response and disaster management,(2) review, comparison, and evaluation of shortest path algorithms from an emergency response and disaster management point of view, (3) proposing a vulnerability assessment approach, and (4) proposing a real-time indoor emergency guidance and navigation system framework for buildings under the threat of multi-hazard emergencies. The findings of the research can be used in future studies on emergency response and disaster management domains.

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...
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 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 ...
Identification and representation of information items required for vulnerability assessment and multi-hazard emergency response operations
Gökdemir, Nuray; Birgönül, Mustafa Talat; Department of Civil Engineering (2011)
Emergency response teams, need various internal information about facilities such as building usage type, number of floors, occupancy information, building contents and vulnerable locations in facility during and immediately after multi hazard emergencies. Accessing such information accurately and timely is very important in order to speed up the guidance of occupants in a facility that is under the effect of multi-hazards to safe exits and speed up the decision process of emergency response teams to identi...
A Methodology for Seismic Loss Estimation in Urban Regions Based on Ground-Motion Simulations
Ugurhan, Beliz; Askan Gündoğan, Ayşegül; Erberik, Murat Altuğ (2011-04-01)
Seismic vulnerability assessment of residential buildings in regions of high seismicity is an interdisciplinary problem requiring major inputs from fields of seismology and earthquake engineering. The basic two components of loss estimation methods are information on regional seismicity and building stock. This study presents a realistic loss estimation methodology where the first component, input ground motions, is obtained from regional ground-motion simulations using the stochastic finite-fault technique...
