Available in PDF, EPUB and Kindle. Book excerpt: Recent world events have drawn attention to threats that extend to the civilian population. A protective design approach for retrofit of existing structures has become increasingly palatable, despite the high costs, because of terror threats that were once considered "remote." Windows have always been one of the weakest points in most structures, primarily because of the requirement for transparency. Recent research at the Air Force Research Laboratory (AFRL) has addressed the difficult problem of retrofitting windows against the "combined threat" of a bomb blast followed by a chem-bio attack. In the recent Gulf War, several specific threats were highlighted for both US military forces and Israeli civilians. The most obvious threat to civilians in that conflict was explosive, as about forty SCUD missiles were launched into civilian areas of Israel. Less obvious, but even more potentially dangerous, was the threat of chem-bio weapons of mass destruction. Recognizing the weakness of entry points to chem-bio contamination, many Israeli civilians used plastic sheeting on the interior side of their windows during periods of increased threat. Recent research at AFRL has shown that, although cost-effective, this approach is woefully inadequate at the blast-pressures which would be expected in a terror attack, as clearly demonstrated by a sequence of still frames taken from blast test videotapes. The paper briefly discusses early pioneering work at AFRL that dealt with the use of clear polymer membranes (i.e., plastic sheets) to combat the combined threat, but the body of the paper focuses on recent developments in the evolution of "membrane" windows. The AFRL windows will resist blast high blast pressures, and will remain sealed against subsequent chem-bio attack, due to a patent-pending design which includes sever.

Available in PDF, EPUB and Kindle. Book excerpt: Recent research at the Air Force Research Laboratory (AFRL) has addressed the difficult problem of lightweight, blast-resistant doors which can be used in structural retrofits (or new construction) to combat the threat of terrorist bombing. Doors have always been one of the weakest points in most structures, primarily because of the requirement for convenient human access. In some hardened structures, very thick steel doors provide adequate blast protection; but these heavyweight doors are not readily adaptable to more general-purpose, lighter-weight structures, such as businesses and homes. The design problems which must be addressed in creating a lightweight, blast-resistant door can be grouped into three general areas: (1) the door must be lightweight; (2) the door must be capable of withstanding the blast-pressure; and (3) the frame must be capable of holding the blast-resistant door. The first two areas are obvious, but the latter is often overlooked. Stated more specifically, if the "blast-proof" door cannot be contained by the door frame, it will become a large, rigid, and life-threatening projectile. The body of the paper focuses on the specific materials and techniques used to create the AFRL lightweight, blast-resistant doors. These doors use a patent-pending design to resist blast-pressures far above any commercially- available "lightweight" door. In fact, the AFRL blast-resistant doors can achieve protection, with a relatively simple retrofit, that would otherwise require significant and substantial structural modifications. Results from AFRL blast tests on the doors are presented, which clearly show their capability under extremely high blast pressures.

Book excerpt: Terrorist bombs threaten American civilians and military personnel both at home and abroad. Analysis of data from previous terror attacks indicates the largest number of injuries result from projected glass shards from shattered windows and facades. Three key issues have led to increased interest in new window materials as well as changes in building design codes: (1) actual terror attacks, (2) the threat of future terror attacks, and (3) monetary losses due to hurricanes. New protective products include a wide variation of films and laminated glasses for retrofit and replacement. Air Force Research Laboratory (AFRL) research has shown that these protective films will reduce the fragmentation of the enclosed glass. However, protective films that are not anchored will not provide retention of the film/glass system under the severe blast loadings expected from terror bombs. This paper introduces the Flex window, a patent-pending blast-resistant window developed at AFRL, along with key design concepts. In addition, the paper presents results from actual blast tests of the Flex window. Tabular data and photo-documentation is used to illustrate the ability of the Flex window to handle blast pressures a full order of magnitude greater than the typical commercial "blast proof" window. New AFRL methods for modeling both exterior and interior loading functions are presented. In addition, possible response modes are discussed based on observations of high-speed video recordings.

Available in PDF, EPUB and Kindle. Book excerpt: Recent world events have drawn attention to threats that extend beyond deployed forces to the civilian population. In the recent Gulf War, several specific threats were highlighted for both U.S. military forces and Israeli civilians. The most obvious threat to civilians in that conflict was explosive. Less obvious, but even more potentially dangerous, was the threat of chemical-biological weapons of mass destruction. The key in "protective design" is to define the weak points in a structure and reduce the threat at those points. The paper discusses early pioneering work on blast-resistant windows, at the Air Force Research Laboratory (AFRL/MLQD), that dealt with the use of applied polymer membranes to combat the combined threat of blast and chemical-biological attacks. The paper discusses the evolution of "membrane" windows, right up to the present, where a combination of rigid and flexible components, membranes, anchoring techniques, and pressure relief ports are used to create a window that can withstand the pressure expected from a large blast and afterwards retain membrane integrity sufficient to resist a subsequent chemical-biological attack. Specific improvements that have increased the survivability of the window are discussed, as are improvements currently being tested that should allow these windows to be expanded to "store-front" size without a degradation in protection.

Book excerpt: The confluence of the September 11, 2001 terrorist attack and the U.S. Army's historic role to support civil authorities has resulted in substantial new challenges for the Army. To help meet these challenges, the Assistant Secretary of the Army for Research and Technology requested the National Research Council (NRC) carry out a series of studies on how science and technology could assist the Army prepare for its role in homeland security (HLS). The NRC's Board on Army Science and Technology formed the Committee on Army Science and Technology for Homeland Security to accomplish that assignment. The Committee was asked to review relevant literature and activities, determine areas of emphasis for Army S&T in support of counter terrorism and anti-terrorism, and recommend high-payoff technologies to help the Army fulfill its mission. The Department of Defense Counter-Terrorism Technology Task Force identified four operational areas in reviewing technical proposals for HLS operations: indications and warning; denial and survivability; recovery and consequence management; and attribution and retaliation. The study sponsor asked the Committee to use these four areas as the basis for its assessment of the science and technology (S&T) that will be important for the Army's HLS role. Overall, the Committee found that: There is potential for substantial synergy between S&T work carried out by the Army for its HLS responsibilities and the development of the next generation Army, the Objective Force. The Army National Guard (ARNG) is critical to the success of the Army's HLS efforts.

This book was released on 2013-01-26 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: This manual is intended to provide guidance for engineers, architects, building officials, and property owners to design shelters and safe rooms in buildings. It presents information about the design and construction of shelters in the work place, home, or community building that will provide protection in response to manmade hazards. The information contained herein will assist in the planning and design of shelters that may be constructed outside or within dwellings or public buildings. These safe rooms will protect occupants from a variety of hazards, including debris impact, accidental or intentional explosive detonation, and the accidental or intentional release of a toxic substance into the air. Safe rooms may also be designed to protect individuals from assaults and attempted kidnapping, which requires design features to resist forced entry and ballistic impact. This covers a range of protective options, from low-cost expedient protection (what is commonly referred to as sheltering-in-place) to safe rooms ventilated and pressurized with air purified by ultra-high-efficiency filters. These safe rooms protect against toxic gases, vapors, and aerosols. The contents of this manual supplement the information provided in FEMA 361, Design and Construction Guidance for Community Shelters and FEMA 320, Taking Shelter From the Storm: Building a Safe Room Inside Your House. In conjunction with FEMA 361 and FEMA 320, this publication can be used for the protection of shelters against natural disasters. This guidance focuses on safe rooms as standby systems, ones that do not provide protection on a continuous basis. To employ a standby system requires warning based on knowledge that a hazardous condition exists or is imminent. Protection is initiated as a result of warnings from civil authorities about a release of hazardous materials, visible or audible indications of a release (e.g., explosion or fire), the odor of a chemical agent, or observed symptoms of exposure in people. Although there are automatic detectors for chemical agents, such detectors are expensive and limited in the number of agents that can be reliably detected. Furthermore, at this point in time, these detectors take too long to identify the agent to be useful in making decisions in response to an attack. Similarly, an explosive vehicle or suicide bomber attack rarely provides advance warning; therefore, the shelter is most likely to be used after the fact to protect occupants until it is safe to evacuate the building. Two different types of shelters may be considered for emergency use, standalone shelters and internal shelters. A standalone shelter is a separate building (i.e., not within or attached to any other building) that is designed and constructed to withstand the range of natural and manmade hazards. An internal shelter is a specially designed and constructed room or area within or attached to a larger building that is structurally independent of the larger building and is able to withstand the range of natural and manmade hazards. Both standalone and internal shelters are intended to provide emergency refuge for occupants of commercial office buildings, school buildings, hospitals, apartment buildings, and private homes from the hazards resulting from a wide variety of extreme events. The shelters may be used during natural disasters following the warning that an explosive device may be activated, the discovery of an explosive device, or until safe evacuation is established following the detonation of an explosive device or the release of a toxic substance via an intentional aerosol attack or an industrial accident. Standalone community shelters may be constructed in neighborhoods where existing homes lack shelters. Community shelters may be intended for use by the occupants of buildings they are constructed within or near, or they may be intended for use by the residents of surrounding or nearby neighborhoods or designated areas.

Book excerpt: Unique single reference supports functional and cost-efficient designs of blast resistant buildings Now there's a single reference to which architects, designers, and engineers can turn for guidance on all the key elements of the design of blast resistant buildings that satisfy the new ASCE Standard for Blast Protection of Buildings as well as other ASCE, ACI, and AISC codes. The Handbook for Blast Resistant Design of Buildings features contributions from some of the most knowledgeable and experienced consultants and researchers in blast resistant design. This handbook is organized into four parts: Part 1, Design Considerations, sets forth basic principles, examining general considerations in the design process; risk analysis and reduction; criteria for acceptable performance; materials performance under the extraordinary blast environment; and performance verification for technologies and solution methodologies. Part 2, Blast Phenomena and Loading, describes the explosion environment, loading functions needed for blast response analysis, and fragmentation and associated methods for effects analysis. Part 3, System Analysis and Design, explains the analysis and design considerations for structural, building envelope, component space, site perimeter, and building system designs. Part 4, Blast Resistant Detailing, addresses the use of concrete, steel, and masonry in new designs as well as retrofitting existing structures. As the demand for blast resistant buildings continues to grow, readers can turn to the Handbook for Blast Resistant Design of Buildings, a unique single source of information, to support competent, functional, and cost-efficient designs.

This book was released on 2003-09-05 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Individuals may have to rely on themselves to protect their own health and safety--perhaps even their own lives--in the event of a terrorist attack. Even those who know how to take care of themselves in the event of a fire, tornado, or earthquake might not know what to do in case of a chemical, radiological, nuclear, or biological attack. This quick guide attempts to fill in some of these gaps by offering specific actions to take during each of these situations, as well as preparations that can be taken. These actions are appropriate regardless of the likelihood of an attack, its scale, or the current government alert level; are designed to be sensitive to potential variations; and have been defined in terms of simple rules that should be easy to follow. A reference card included at the back of the guide encapsulates the key points and can be removed for display in a prominent place.

Available in PDF, EPUB and Kindle. Book excerpt: First published in 2003, this account of the anti-terrorist measures of London's financial district and the changes in urban security after 9/11 has been revised to take into account developments in counter-terrorist security and management, particularly after the terrorist attack in London on July 7th 2005. It makes a valuable addition to the current debate on terrorism and the new security challenges facing Western nations. Drawing on the post-9/11 academic and policy literature on how terrorism is reshaping the contemporary city, this book explores the changing nature of the terrorist threat against global cities in terms of tactics and targeting, and the challenge of developing city-wide managerial measures and strategies. Also addressed is the way in which London is leading the way in developing best practice in counter-terrorist design and management, and how such practice is being internationalized.
