Examples for calculations are provided. The aim is to significantly improve the understanding of fire safety engineering in tunnels. Chapters on fuel and ventilation control, combustion products, gas temperatures, heat fluxes, smoke stratification, visibility, tenability, design fire curves, heat release, fire suppression and detection, CFD modeling, and scaling techniques all equip readers to create their own fire safety plans for tunnels. This book should be purchased by any engineer or public official with responsibility for tunnels. It would also be of interest to many fire protection engineers as an application of evolving technical principles of fire safety.
Guidelines for Emergency Ventilation Smoke Control in Roadway Tunnels by Igor Y. Maevski Pdf
"TRB's National Cooperative Highway Research Program (NCHRP) Research Report 836: Guidelines for Emergency Ventilation Smoke Control in Roadway Tunnels presents guidelines for ventilation in roadway tunnels to facilitate human evacuation and emergency responder safety. These guidelines consider tunnel geometrics such as tunnel altitude; physical dimensions (i.e., length, cross section); type of traffic flow (i.e., single or bi-directional flow); and fan utilization and placement. They also consider cargo types and quantities as they pertain to fire heat release rates (FHRRs) and ventilation requirements. The guidelines determine the effects of ventilation on tunnel fires including fire size, and the interaction of firefighting and ventilation system operation. " -- Publisher description
Road Tunnels by Fabio Borghetti,Paolo Cerean,Marco Derudi,Alessio Frassoldati Pdf
This book illustrates a new quantitative risk analysis model for road tunnels that is capable of evaluating the role of infrastructure measures, equipment and management procedures as prescribed by EU Directive 2004/54/EC. The risk assessment draws on the typical F-N curves of societal risk, evaluated with the help of event tree analysis, vehicle queue formation dynamics, and users’ egress and tenability models. In addition, the model considers the reliability of the safety measures. The work provides essential guidance on the following aspects: how a quantitative model can be implemented to evaluate risk in road tunnels; how to build an event tree for the accident scenarios considered; how to simulate the vehicle queue formation; how to simulate the evolution of accident scenarios; and how to simulate the users’ egress. Given its scope and depth of coverage, the book will be of interest to all engineers whose work involves fire protection and safety in tunnels, all persons engaged in safety and transport engineering or risk analysis for road tunnels, as well as public and private bodies involved in the application of Directive 2004/54/EC.
The ventilation system is an important element for the safety of a tunnel, as well as its investment and operating costs. Investors, operators and designers of road tunnels bear a responsibility for the safety of persons, as well as for important investment decisions. The new Road Tunnel Ventilation Compendium fosters understanding of basic aspects of ventilation in the context of tunnel safety, describes the actual state of the art and shows how to design and realise safer tunnels, at lower costs, with reliably functioning systems.
Engineering for Extremes by Mark G. Stewart,David V. Rosowsky Pdf
The volume explains how risk and decision-making analytics can be applied to the wicked problem of protecting infrastructure and society from extreme events. There is increasing research that takes into account the risks associated with the timing and severity of extreme events in engineering to reduce the vulnerability or increase the resiliency of infrastructure. "Engineering for extremes" is defined as measures taken to reduce the vulnerability or increase the resiliency of built infrastructure to climate change, hurricanes, storms, floods, earthquakes, heat waves, fires, and malevolent and abnormal events that include terrorism, gas explosions, vehicle impact and vehicle overload. The book introduces the key concepts needed to assess the economic and social well-being risks, costs and benefits of infrastructure to extreme events. This includes hazard modelling (likelihood and severity), infrastructure vulnerability, resilience or exposure (likelihood and extent of damage), social and economic loss models, risk reduction from protective measures, and decision theory (cost-benefit and utility analyses). Case studies authored by experts from around the world describe the practical aspects of risk assessment when deciding on the most cost-efficient measures to reduce infrastructure vulnerability to extreme events for housing, buildings, bridges, roads, tunnels, pipelines, and electricity infrastructure in the developed and developing worlds.
Provides a deeper understanding of how fire behaves during enclosure fires, primarily in smaller areas such as apartments and houses (dwellings). Focuses on the mechanisms that control flashovers, such as flame spread and reradiation from the smoke gas layer and how to recognize the signs of an imminent flashover in order to minimize the risks involved in the fire service's operations. [Note: The Swedish methodology of dealing with flashover differs somewhat from the American.]
Designing Steel Structures for Fire Safety by Jean Marc Franssen,Venkatesh Kodur,Raul Zaharia Pdf
Structural design in fire conditions is conceptually similar to structural design in normal temperature conditions, but often more difficult because of internal forces induced by thermal expansion, strength reduction due to elevated temperatures, much larger deflections, and numerous other factors. Before making any design decisions it is esse
Directions of Development of Transport Networks and Traffic Engineering by Elżbieta Macioszek,Grzegorz Sierpiński Pdf
This book offers a collection of valuable guidelines for making decisions concerning the future development of transport networks and traffic engineering. The decision-making support systems described here will certainly attract the interest of those who face the challenge of finding solutions to problems concerning modern transport systems on a daily basis. Consequently, the book is chiefly intended for local authorities involved in planning and preparing development strategies for specific transport-related areas (in both urban and regional contexts), as well as for representatives of business and industry who are directly engaged in the implementation of traffic engineering solutions. The guidelines provided in the respective chapters help to address the given problem soundly, and to simplify the selection of an appropriate strategy. The topics covered include increasing the competitiveness of public transport, the status quo of electric vehicle infrastructures worldwide, methods for calming urban traffic as an element of sustainable transport development, speed traffic zones and electric buses, car-sharing systems in Poland, a method for deconstructing the regional travel demand model, monitoring urban traffic using floating car data, problems of deliveries in urban agglomeration distribution systems, estimating the number of threatened people in case of fire in road tunnels, and road pavement evaluation using advanced tools. Since the book also considers new approaches to theoretical models (including traffic flow surveys and measurements, transport behaviors, human factors in traffic engineering, and road condition modeling), it will also appeal to researchers and scientists studying these problems. The book gathers selected papers presented at the 15th Scientific and Technical Conference “Transport Systems. Theory and Practice”, organized by the Department of Transport Systems and Traffic Engineering, Silesian University of Technology in Katowice, Poland on September 17–19, 2018.
“Eco-lit needs more attention, and devotees will be pleased to discover a new addition from the Icelandic author Andri Snaer Magnason, who writes with a Seussian mix of wonder, wit and gravitas ... immensely satisfying.”—New York Times Longlisted for the 2022 National Translation Award • Finalist for the 2021 Nordic Council Literature Prize • A Winnipeg Free Press Top Read of 2021 Asked by a leading climate scientist why he wasn’t writing about the greatest crisis mankind has faced, Andri Snær Magnason, one of Iceland’s most beloved writers and public intellectuals, protested: he wasn’t a specialist, he said. It wasn’t his field. But the scientist persisted: “If you cannot understand our scientific findings and present them in an emotional, psychological, poetic or mythological context,” he told him, “then no one will really understand the issue, and the world will end.” Based on interviews and advice from leading glacial, ocean, climate, and geographical scientists, and interwoven with personal, historical, and mythological stories, Magnason’s resulting response is a rich and compelling work of narrative nonfiction that illustrates the reality of climate change and offers hope in the face of an uncertain future. Moving from reflections on how one writes an obituary for a glacier to exhortation for a heightened understanding of human time and our obligations to one another, throughout history and across the globe, On Time and Water is both deeply personal and globally minded: a travel story, a world history, a desperate plea to live in harmony with future generations—and is unlike anything that has yet been published on the current climate emergency.
