Available in PDF, EPUB and Kindle. Book excerpt: Evacuation calculations are increasingly becoming a part of performance-based analyses to assess the level of life safety provided in buildings. In some cases, engineers are using back-ofthe- envelope (hand) calculations to assess life safety, and in others, computational evacuation models are being used. This paper presents a review of 26 current computer evacuation models, and is an updated version of a previous review published in 2005. Models are categorized by their availability, overarching method of simulating occupants, purpose, type of grid/structure, perspective of the occupants, perspective of the building, internal algorithms for simulating occupant behavior and movement, the incorporate of fire effects, the use of computer-aided design drawings, visualization methods, and validation techniques. Models are also categorized based upon whether they simulate special features of an evacuation, including counterflow, exit blockages, fire conditions that affect behavior, incapacitation of the occupants due to toxic smoke products, group behavior, disabled or slower-moving occupant effects, pre-evacuation delays, elevator usage, and occupant route choice.

This book was released on 2014-02-18 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evacuation calculations are increasingly becoming a part of performance-based analyses to assess the level of life safety provided in buildings. In some cases, engineers are using back-of-the-envelope (hand) calculations to assess life safety, and in others, evacuation models are being used. Hand calculations usually follow the equations given in the Emergency Movement Chapter of the Society of Fire Protection Engineers (SFPE) Handbook2 to calculate mass flow evacuation from any height of building. The occupants are assumed to be standing at the doorway to the stair on each floor as soon as the evacuation begins. The calculation focuses mainly on points of constriction throughout the building (commonly the door to the outside) and calculates the time for the occupants to flow past these points and to the outside.
Download or read book Evacuation Modeling Trends written by Arturo Cuesta and published by Springer. This book was released on 2015-10-17 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an overview of modeling definitions and concepts, theory on human behavior and human performance data, available tools and simulation approaches, model development, and application and validation methods. It considers the data and research efforts needed to develop and incorporate functions for the different parameters into comprehensive escape and evacuation simulations, with a number of examples illustrating different aspects and approaches. After an overview of basic modeling approaches, the book discusses benefits and challenges of current techniques. The representation of evacuees is a central issue, including human behavior and the proper implementation of representational tools. Key topics include the nature and importance of the different parameters involved in ASET and RSET and the interactions between them. A review of the current literature on verification and validation methods is provided, with a set of recommended verification tests and examples of validation tests. The book concludes with future challenges: new scenarios and factors for future model developments, addresses the problem of using deterministic and/or stochastic approaches and proposes, and discusses the use of evacuation models for supporting timely decisions in real-time. Written by international experts, Evacuation Modeling Trends is designed for those involved in safety, from emergency and intervention personnel to students, engineers and researchers.
Download or read book The Process of Verification and Validation of Building Fire Evacuation Models written by National Institute of Standards and Technology and published by CreateSpace. This book was released on 2014-02-24 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: To date, there is no International standard on the methods and tests to assess the verification and validation (V&V) of building fire evacuation models, i.e., model testers adopt inconsistent procedures or tests designed for other model uses. For instance, the tests presented within the MSC/Circ.1238 Guidelines for evacuation analysis for new and existing passenger ships provided by the International Maritime Organization are often employed for the V&V of models outside their original context of use (building fires instead of maritime applications). This document discusses the main issues associated with the definition of a standard procedure for the V&V of building fire evacuation models. A review of the current procedures, tests (e.g. the MSC/Circ.1238 Guidelines), and methods available in the literature to assess the V&V of building evacuation models is provided. The capabilities of building evacuation models are evaluated studying their five main core components, namely 1) Pre-evacuation time, 2) Movement and Navigation, 3) Exit usage, 4) Route availability and 5) Flow constraints. A set of tests and recommendations about the verification of building evacuation models is proposed. Suggestions on simple qualitative validation tests are provided together with examples of experimental data-sets suitable for the analysis of different core components. The uncertainties associated with evacuation modelling are discussed. In particular, a method for the analysis of behavioural uncertainty (uncertainty due to the use of distributions or stochastic variables to simulate human behaviour in evacuation modelling) is presented. The method consists of a set of convergence criteria based on functional analysis. The last part of this document presents a discussion on the definition of the acceptance criteria for a standard V&V protocol.
Download or read book Large Scale Evacuation written by Michael K. Lindell and published by CRC Press. This book was released on 2018-12-07 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large-Scale Evacuation introduces the reader to the steps involved in evacuation modelling for towns and cities, from understanding the hazards that can require large-scale evacuations, through understanding how local officials decide to issue evacuation advisories and households decide whether to comply, to transportation simulation and traffic management strategies. The author team has been recognized internationally for their research and consulting experience in the field of evacuations. Collectively, they have 125 years of experience in evacuation, including more than 140 projects for federal and state agencies. The text explains how to model evacuations that use the road transportation network by combining perspectives from social scientists and transportation engineers, fields that have commonly approached evacuation modelling from distinctly different perspectives. In doing so, it offers a step-by-step guide through the key questions needed to model an evacuation and its impacts to the evacuation route system as well as evacuation management strategies for influencing demand and expanding capacity. The authors also demonstrate how to simulate the resulting traffic and evacuation management strategies that can be used to facilitate evacuee movement and reduce unnecessary demand. Case studies, which identify key points to analyze in an evacuation plan, discuss evacuation termination and re-entry, and highlight challenges that someone developing an evacuation plan or model should expect, are also included. This textbook will be of interest to researchers, practitioners, and advanced students.
Download or read book Assessment of Total Evacuation Systems for Tall Buildings written by Enrico Ronchi and published by Springer. This book was released on 2014-05-27 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SpringerBrief focuses on the use of egress models to assess the optimal strategy for total evacuation in high-rise buildings. It investigates occupant relocation and evacuation strategies involving the exit stairs, elevators, sky bridges and combinations thereof. Chapters review existing information on this topic and describe case study simulations of a multi-component exit strategy. This review provides the architectural design, regulatory and research communities with a thorough understanding of the current and emerging evacuation procedures and possible future options. A model case study simulates seven possible strategies for the total evacuation of two identical twin towers linked with two sky-bridges at different heights. The authors present the layout of the building and the available egress components including both vertical and horizontal egress components, namely stairs, occupant evacuation elevators (OEEs), service elevators, transfer floors and sky-bridges. The evacuation strategies employ a continuous spatial representation evacuation model (Pathfinder) and are cross-validated by a fine network model (STEPS). Assessment of Total Evacuation Systems for Tall Buildings is intended for practitioners as a tool for analyzing evacuation methods and efficient exit strategies. Researchers working in architecture and fire safety will also find the book valuable.

Download or read book Survival Psychology written by J. Leach and published by Springer. This book was released on 1994-09-05 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: '...it should be made standard reading for those dealing with disaster/survival situations, it is also very informative in helping the general reader understand the psychology of survivors...The text makes compulsive reading and the book is hard to put down. It is worth examining, no matter where your professional interest lies.'- Duncan MacPaul, Nursing Times. Why do so many people die without need? How can an exceptional few survive extraordinarily harsh conditions sometimes after months or years of deprivation? Recent years have seen remarkable improvements in survival training and technology, yet most people still perish quickly in the face of adversity. In this book John Leach seeks to answer these questions by considering the psychology of human survival; how groups and individuals behave before, during and after life threatening events. Both short and long-term survival are addressed as well as the psychological consequences of hunger, thirst, cold, heat, crowding, isolation, fatigue and sleep deprivation. The essence of this work is distilled into a set of principles for psychological first-aid for use in the field.
Download or read book Building Performance Analysis written by Pieter de Wilde and published by John Wiley & Sons. This book was released on 2018-05-31 with total page 619 pages. Available in PDF, EPUB and Kindle. Book excerpt: Explores and brings together the existent body of knowledge on building performance analysis Shortlisted in the CIBSE 2020 Building Performance Awards Building performance is an important yet surprisingly complex concept. This book presents a comprehensive and systematic overview of the subject. It provides a working definition of building performance, and an in-depth discussion of the role building performance plays throughout the building life cycle. The book also explores the perspectives of various stakeholders, the functions of buildings, performance requirements, performance quantification (both predicted and measured), criteria for success, and the challenges of using performance analysis in practice. Building Performance Analysis starts by introducing the subject of building performance: its key terms, definitions, history, and challenges. It then develops a theoretical foundation for the subject, explores the complexity of performance assessment, and the way that performance analysis impacts on actual buildings. In doing so, it attempts to answer the following questions: What is building performance? How can building performance be measured and analyzed? How does the analysis of building performance guide the improvement of buildings? And what can the building domain learn from the way performance is handled in other disciplines? Assembles the current body of knowledge on building performance analysis in one unique resource Offers deep insights into the complexity of using building performance analysis throughout the entire building life cycle, including design, operation and management Contributes an emergent theory of building performance and its analysis Building Performance Analysis will appeal to the building science community, both from industry and academia. It specifically targets advanced students in architectural engineering, building services design, building performance simulation and similar fields who hold an interest in ensuring that buildings meet the needs of their stakeholders.

Download or read book Visual Analysis of Situationally Aware Building Evacuations written by Jackie Dean Jr Guest and published by . This book was released on 2012 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rapid evacuation of large urban structures (campus buildings, arenas, stadiums, etc.) is a complex operation and of prime interest to emergency responders and planners. Although there is a considerable body of work in evacuation algorithms and methods, most of these are impractical to use in real-world scenarios (non real¬time, for instance) or have difficulty handling scenarios with dynamically changing conditions. Our goal in this work is towards developing computer visualizations and real-time visual analytic tools for building evacuations, in order to provide situational awareness and decision support to first responders and emergency planners. We have augmented traditional evacuation algorithms in the following important ways, (1) fa-cilitate real-time complex user interaction with first responder teams, as information is received during an emergency situation, (2) visual reporting tools for spatial occu¬pancy, temporal cues, and procedural recommendations are provided automatically and at adjustable levels, and (3) multi-scale building models, heuristic evacuation models, and unique graph manipulation techniques for producing near real-time sit¬uational awareness. We describe our system, methods and their application using campus buildings as an example. We also report the results of evaluating our system in collaboration with our campus police and safety personnel, via a table-top exercise consisting of 3 different scenarios, and their resulting assessment of the system.
Download or read book Decision making Analysis and Optimization Modeling of Emergency Warnings for Major Accidents written by Wenmei Gai and published by Springer. This book was released on 2018-11-03 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights cutting-edge research into emergency early warning management and decision-making for severe accidents. Using toxic gas leakages as examples, it puts forward new design methods for emergency early warning systems, as well as a systematic description of emergency early warning information communication mechanisms and characteristics of regional evacuation, based on a wide range of theories, including safety engineering, information engineering, communication, behaviorology and others. The book applies a range of methods, such as case analysis, questionnaire interviews, and multi-objective optimization modeling. Drawing on this basis, it subsequently proposes a multi-objective optimization modeling and algorithm for emergency path selection, together with an evacuation risk assessment method. Divided into six chapters prepared by an international team of researchers, the book addresses the design of early warning systems, communication and dissemination mechanisms of early warning information, characteristics of regional evacuation, multi-objective optimization of emergency paths, and evacuation risk assessment. The book offers an essential reference guide for engineering technicians and researchers in a wide range of fields, including emergency management, safety science and engineering, disaster relief engineering, and transportation optimization, as well as graduate students in related majors at colleges and universities.
Download or read book Pedestrian and Evacuation Dynamics written by Richard D. Peacock and published by Springer Science & Business Media. This book was released on 2011-06-29 with total page 862 pages. Available in PDF, EPUB and Kindle. Book excerpt: An aging population, increasing obesity and more people with mobility impairments are bringing new challenges to the management of routine and emergency people movement in many countries. These population challenges, coupled with the innovative designs being suggested for both the built environment and other commonly used structures (e.g., transportation systems) and the increasingly complex incident scenarios of fire, terrorism, and large-scale community disasters, provide even greater challenges to population management and safety. Pedestrian and Evacuation Dynamics, an edited volume, is based on the Pedestrian and Evacuation Dynamics (PED) 5th International 2010 conference, March 8th-10th 2010, located at the National Institute of Standards and Technology, Gaithersburg, MD, USA. This volume addresses both pedestrian and evacuation dynamics and associated human behavior to provide answers for policy makers, designers, and emergency management to help solve real world problems in this rapidly developing field. Data collection, analysis, and model development of people movement and behavior during nonemergency and emergency situations will be covered as well.
