Book excerpt: Terrorist attacks and other destructive incidents caused by explosives have, in recent years, prompted considerable research and development into the protection of structures against blast loads. For this objective to be achieved, experiments have been performed and theoretical studies carried out to improve our assessments of the intensity as well as the space-time distribution of the resulting blast pressure on the one hand and the consequences of an explosion to the exposed environment on the other.This book aims to enhance awareness on and understanding of these topical issues through a collection of relevant, Transactions of the Wessex Institute of Technology articles written by experts in the field. The book starts with an overview of key physics-based algorithms for blast and fragment environment characterisation, structural response analyses and structural assessments with reference to a terrorist attack in an urban environment and the management of its inherent uncertainties.A subsequent group of articles is concerned with the accurate definition of blast pressure, which is an essential prerequisite to the reliable assessment of the consequences of an explosion. Other papers are concerned with alternative methods for the determination of blast pressure, based on experimental measurements or neural networks. A final group of articles reports investigations on predicting the response of specific structural entities and their contents.The book concludes with studies on the effectiveness of steel-reinforced polymer in improving the performance of reinforced concrete columns and the failure mechanisms of seamless steel pipes used in nuclear industry.
Download or read book Prediction of 3 D Blast Loading on a Partially Open Industrial Building Feasibility Study written by John D. Wortman and published by . This book was released on 1981 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The modified 3-D HULL hydrocode is used to calculate the blast loading on a partially-open, industrial-type building struck by a 32.8 kPa (4.75 psi) overpressure shock at oblique incidence. The feasibility of predicting the net unsteady loading on the front and back walls of the building is demonstrated. The predicted loading appears to be qualitatively correct; further studies will be necessary to assess the quantitative results and extend the analysis to other types of structures. (Author).

This book was released on 2006 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dissertation responds to the need for efficient techniques for testing and validating protective technologies to resist explosive loading on civil structures; the newly-developed Explosive Loading Laboratory allows investigators to simulate explosive blast loading at a lower cost and with better data than when using real explosives. Analytical tools are developed for the new laboratory and comparisons between real and simulated explosive tests confirm that the two are equivalent. These developments provide future investigators with confidence in the simulated blast methodology and tools to predict results and analyze the data, thus setting the stage for decades of fruitful research in a nascent field of simulated explosive testing. The simulated blast load is applied via specially designed apparatuses called blast generators, each of which is made of a high speed actuator that accelerates an impacting module towards the specimen. An elastomeric pad, called the programmer, on the front of the impacting module provides a blast-like pressure pulse to the specimen. The entire setup is housed in a post-tensioned, self-reacting, reinforced concrete reaction structure. An inaugural series of tests on column specimens provides data on structural behavior and on the functioning of the laboratory. New methods of data analysis are developed: the equivalent uniform load method reduces the load recorded on multiple channels to a single, rationally-derived value, and the equivalent charge method translates the experimental results to an equivalent real scenario. Because there is no fireball to obscure the specimen during the blast, the verbal descriptions and video stills herein are the first-ever visual record of structural behavior under blast loading. The laboratory results are corroborated with field test data via qualitative comparisons and demand-damage plots to demonstrate the validity of simulated blast testing. A methodology is developed for quickly and easily determining the necessary velocity of the impacting module to deliver a desired impulse to the specimen. Load-deformation programmer data are collected and a phenomenological model of programmer behavior is derived for use in detailed pre-test analyses, including finite element implementations. Both tools are derived theoretically, calibrated to experimental data, and verified against independent experimental data.

Download or read book Structural Design for Physical Security written by Task Committee on Structural Design for Physical Security and published by ASCE Publications. This book was released on 1999-01-01 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prepared by the Task Committee on Structural Design for Physical Security of the Structural Engineering Institute of ASCE. This report provides guidance to structural engineers in the design of civil structures to resist the effects of terrorist bombings. As dramatized by the bombings of the World Trade Center in New York City and the Murrah Building in Oklahoma City, civil engineers today need guidance on designing structures to resist hostile acts. The U.S. military services and foreign embassy facilities developed requirements for their unique needs, but these the documents are restricted. Thus, no widely available document exists to provide engineers with the technical data necessary to design civil structures for enhanced physical security. The unrestricted government information included in this report is assembled collectively for the first time and rephrased for application to civilian facilities. Topics include: determination of the threat, methods by which structural loadings are derived for the determined threat, the behavior and selection of structural systems, the design of structural components, the design of security doors, the design of utility openings, and the retrofitting of existing structures. This report transfers this technology to the civil sector and provides complete methods, guidance, and references for structural engineers challenged with a physical security problem.
