Fuzzy-based escape route fire-vulnerability assessment model for indoor built environment

Fire safety evaluation is rarely involved in the iterative building design process except for legislative approval phases compared to other building objectives. However, regardless of architectural design priorities, all buildings should have adequate fire protection. This research develops a fire vulnerability assessment model based on the impact of architects on fire protection and effects of building design characteristics on fire safety. Inherent to the uncertain nature of fire safety evaluation practice, this study proposes a fuzzy vulnerability decision-making methodology to detect and visualize escape route vulnerabilities, which have the highest impact on the interoperability of fire safety and architectural design practices. The model was validated in an opera house building since the assembly occupancies have specific importance due to the significant number of fire causalities. The escape routes of the case study building were evaluated for materials' fire reaction, route flow, route equipment, means of egress, dimensions and layout input variables. The output vulnerability levels were discussed to enhance the understanding of critical building design factors that contribute to fire vulnerability. The results confirm that the model is fairly effective in the detection and visualization of vulnerability sources by reducing communication time delays and preventing human-induced mistakes.


Using the balanced scorecard as a safety management tool in construction companies : a qfd approach
Şimşek, Burak; Gündüz, Murat; Department of Civil Engineering (2006)
The aim of this thesis is to propose a safety management framework for construction companies. A literature review was performed to identify significant factors that would improve safety performance. Two management tools are used within the scope of this study: the balanced scorecard and quality function deployment (QFD). Strategic goals are established for each perspective of the balanced scorecard: financial and cultural, employee, process and learning and growth. Afterwards, a questionnaire was prepared ...
Yapılı Çevrede Yangın Kırılganlığı ile Konum Belirleme Teknolojilerinin Birleştirilmesi

Yapı güvenliği konusunda, yapı elemanlarının detaylarının biçimsel kararlarında, estetik kaygıların yanı sıra çeşitli standartların ve yönetmeliklerin de etkisi vardır. Mimarlar bu türden etkileri, tasarım süreci başlamadan yapıyı şekillendiren bir durum olarak algılamakta; bu durumu yaratıcı tasarım sürecine kısıtlayıcı etkenler olarak görmekte ve konu ile ilgili araştırmalara tereddütlü yaklaşmaktadırlar. Bu yaklaşım, dayanakları eskilere dayanan ve geçerliği kalmamış olan kuralların deterministik yaklaşı...
Integration of Fire Vulnerability and Indoor Localization in Built Environments

In terms of building safety, various standards and regulations effect the formal decisions of building components besides aesthetic concerns. These effects can be perceived as restrictions for the creative basis of architecture that shape the buildings from the beginning by architects, thus they may be hesitant to building safety-related researches. This idea originates from conventional and invalid regulations with deterministic approaches that are accepted as decisive currently. As opposed to deterministi...
Potential of Biosensors as Indicators of Safe Behavior in Construction Sites
Özel, Bekir Enes ; Pekeriçli, Mehmet Koray (2020-11-12)
Maintaining the safe behavior of construction workers is one of the major aspects of safety management in the AEC industry. Unsafe behavior in hazardous places like construction sites could lead to severe consequences. Meanwhile, measuring and controlling safe behavior is an ambiguous task. Unsafe behavior can have various reasons. It is a very complex issue that includes many hard-to-measure variables. Yet still, most of the time, understanding and analyzing these reasons are done merely ba...
Predicting the outcome of construction incidents
Ayhan, Bilal Umut; Tokdemir, Onur Behzat (Elsevier BV, 2019-03-01)
Ensuring the Occupational Health and Safety (OHS) is the utmost essential issue for all construction projects. The problem with the construction industry is that even though there is a significant emphasis on safety requirements, for most of the contractors unless requested by the client or enforced by law, there is a tendency to undermine safety management to save money especially in the case of competitive bidding including incident collection systems. The objective of this study is to develop a model to ...
