Available in PDF, EPUB and Kindle. Book excerpt: Inhaltsangabe:Introduction: This dissertation is an investigation into the behaviour of externally prestressed structures, focusing on bridge box girders, at the ultimate limit state. The main objective is the ductility and the tendon stress increase up to failure of externally prestressed structures. Their behaviour will be compared to internally prestressed structures. The dissertation may have valuable information for the first stages of the design process for medium span bridges as the study is concerned about the overall safety and efficiency of prestressed concrete bridges by the means of ductility. The aim is also to provide information about the tendon stress at failure, which is required for the detailed design.

This book was released on 2023-07-08 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book introduces the comprehensive analysis methodology regarding progressive collapse, and the critical issues may happen in concrete structures. Main topics include: the influential parameters of the development of the main load-resisting mechanisms; the dynamic effects with sudden column removal scenarios; the contribution of non-structural components to improve the resilience of concrete structures; uncertainties in progressive collapse analysis. Based on the empirical research of the author and his team, the book provides valuable knowledge in the field of progressive collapse and bridges the gap between academic research and practice.

This book was released on 2015-07-01 with total page 1014 pages. Available in PDF, EPUB and Kindle. Book excerpt: Original research on performance of materials under a wide variety of blasts, impacts, severe loading and fireCritical information for protecting buildings and civil infrastructure against human attack, deterioration and natural disastersTest and design data for new types of concrete, steel and FRP materials This technical book is devoted to the empirical and theoretical analysis of how structures and the materials constituting them perform under the extreme conditions of explosions, fire, and impact. Each of the 119 fully refereed presentations is published here for the first time and was selected because of its original contribution to the science and engineering of how materials, bridges, buildings, tunnels and their components, such as beams and pre-stressed parts, respond to potentially destructive forces. Emphasis is placed on translating empirical data to design recommendations for strengthening structures, including strategies for fire and earthquake protection as well as blast mitigation. Technical details are provided on the development and behavior of new resistant materials, including reinforcements, especially for concrete, steel and their composites.

This book was released on 2012-12-06 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: These volumes contain the edited documents presented at the NATO-Sponsored Advanced Research Workshop (ARW) on Partial Pre8tre88ing, from Theory to Practice, held at the CEBTP Research Centre of Saint-Remy-Ies-Chevreuse, France, June 18-22, 1984. The workshop was a direct extension of the International Symposium on Nonlinearity and Continuity in Pre8tre88ed Concrete, organized by the editor at the University of Waterloo, Waterloo, Canada, July 4-6, 1983. The organization of the NATO-ARW on Partial Prestressing was prompted by the need to explain and reduce the wide dirrerences of expert oph:iipn· on the subject, which make more difficult the accep tance of partial prestressing by the profession at large. Specifically, the workshop attempted to: - produce a more unified picture of partial presetressing, by con fronting and, where possible, reconciling some conflicting American and European views on this subject; - bring theoretical advances on partial prestressing within the grasp of engineering practice; - provide the required background for developing some guidelines on the use of partial prestressing, in agreement with existing structural concrete standards. The five themes selected for the workshop agenda were: (1) Problems of Partially Prestressed Concrete (PPC). (2) Partially Prestressed Concrete Members: Static Loading. (3) PPC Members: Repeated and Dynamic Loadings. (4) Continuity in Partially Prestressed Concrete. (5) Practice of Partial Prestressing.
