Available in PDF, EPUB and Kindle. Book excerpt: Mitigating the energy created from a blast has been a topic of utmost importance in the terrorism-feared world of today. Main targets of concern are passageways that are significant to a specific area, such as bridges. These structures are expensive to construct and vulnerable to explosive loads which is why a cost-effective means of blast mitigation must be researched. There are many aspects of bridges that could be damaged when a blast load is applied. These susceptible areas can be strengthened using new-age, high-strength composite materials to ensure the security of the whole structure. These materials are able to sustain larger loads while dissipating higher amounts of energy when compared to conventional building materials. As a result, the response of the entire structure will be minimized when a blast load is applied. Despite the fact that these composites cost more than typical materials, the increase in project cost could be minimized by limiting the use of these high-strength materials for only the critical areas of the bridge. Other cost effective solutions to blast mitigation occur in the preliminary design phase. Eliminating all pressure-amplifying areas would save members and connections should a blast occur. Also, designing a bridge with high vertical clearances above areas of excessive boat traffic would also minimize the resultant forces and stresses from an explosion.

This book was released on 2014 with total page 790 pages. Available in PDF, EPUB and Kindle. Book excerpt: International terrorist organizations have been active across the globe for decades, but attacks against public surface transportation infrastructure constitute a recent trend. Statistical data from past attacks, along with numerous threats received by United States (U.S.) Government authorities, support this claim and render U.S. transportation infrastructure security a national concern. Public highway bridges can be particularly vulnerable to a malevolent attack due predominately to their public accessibility and exposed nature. Furthermore, the sudden failure of a highway bridge located on a major transportation corridor has the potential to cause significant economic loss, human casualties, and societal distress. Motivated by the recent trend of increasing worldwide attacks and identified vulnerabilities associated with public highway bridges, considerable research in the area of bridge security has been carried out over the past decade. While much research is still needed, it is important to begin transitioning the existing knowledge and technology to the appropriate users within the bridge analysis and design community. Accordingly, the main objective of the research described in this dissertation is to facilitate this transition and advance the state of-the-practice in bridge-specific protective analysis and design by developing accurate yet fast-running dynamic response models for reinforced concrete (RC) bridge columns and tower panels subjected to blast loads. Given a threat scenario and bridge component of interest, the RC component response models characterize demand on a selected component and provide an estimate of peak dynamic response and incurred damage. Such fast-running, engineering-level models provide practicing bridge engineers with the ability to readily assess the performance of blast-loaded bridge components without having to rely on time-consuming, costly, and complex resources such as physical testing or high-fidelity finite element simulations. The proposed dynamic response models are also capable of facilitating anti-terrorist/force protection (ATFP) retrofits and rapid in-situ vulnerability assessments of existing bridge components, as well as safe designs of new bridge components. As part of a larger research effort that was chiefly managed by the author of this dissertation, the RC component response models were integrated with similar models for steel bridge towers and high-strength steel cable components to form a comprehensive, component-level vulnerability assessment software for blast-loaded bridges. Therefore, the results of this research synthesize the state-of- the-art in blast-resistant bridge analysis/design and put forth a practical, engineering-level tool to aid in the growing concern of domestic transportation infrastructure security. This contribution to the structural engineering community marks a step towards enhanced resiliency of existing and future U.S. highway bridges.

Available in PDF, EPUB and Kindle. Book excerpt: Earthquake engineering is the ultimate challenge for structural engineers. Even if natural phenomena involve great uncertainties, structural engineers need to design buildings, bridges, and dams capable of resisting the destructive forces produced by them. These disasters have created a new awareness about the disaster preparedness and mitigation. Before a building, utility system, or transportation structure is built, engineers spend a great deal of time analyzing those structures to make sure they will perform reliably under seismic and other loads. The purpose of this book is to provide structural engineers with tools and information to improve current building and bridge design and construction practices and enhance their sustainability during and after seismic events. In this book, Khan explains the latest theory, design applications and Code Provisions. Earthquake-Resistant Structures features seismic design and retrofitting techniques for low and high raise buildings, single and multi-span bridges, dams and nuclear facilities. The author also compares and contrasts various seismic resistant techniques in USA, Russia, Japan, Turkey, India, China, New Zealand, and Pakistan. Written by a world renowned author and educator Seismic design and retrofitting techniques for all structures Tools improve current building and bridge designs Latest methods for building earthquake-resistant structures Combines physical and geophysical science with structural engineering
