Available in PDF, EPUB and Kindle. Book excerpt: In the past, facilities considered to be at the end of their useful life were demolished and replaced with new ones that better met the functional requirements of modern society, including new safety standards. Humankind has recently recognised the threats to the environment and to our limited natural resources due to our relentless determination to destroy the old and build anew. With the awareness of these constraints and the emphasis on sustainability, in future the majority of old structures will be retrofitted to extend their service life as long as feasible. In keeping with this new approach, the EU’s Construction Products Regulation 305/2011, which is the basis of the Eurocodes, included the sustainable use of resources as an "Essential Requirement" for construction. So, the forthcoming second generation of EN-Eurocodes will cover not only the design of new structures, but the rehabilitation of existing ones as well. Most of the existing building stock and civil infrastructures are seismically deficient. When the time comes for a decision to prolong their service life with the help of structural and architectural upgrading, seismic retrofitting may be needed. Further, it is often decided to enhance the earthquake resistance of facilities that still meet their functional requirements and fulfil their purpose, if they are not earthquake-safe. In order to decide how badly a structure needs seismic upgrading or to prioritise it in a population of structures, a seismic evaluation is needed, which also serves as a guide for the extent and type of strengthening. Seismic codes do not sufficiently cover the delicate phase of seismic evaluation nor the many potential technical options for seismic upgrading; therefore research is on-going and the state-of-the-art is constantly evolving. All the more so as seismic evaluation and rehabilitation demand considerable expertise, to make best use of the available safety margins in the existing structure, to adapt the engineering capabilities and techniques at hand to the particularities of a project, to minimise disruption of use, etc. Further, as old structures are very diverse in terms of their materials and layout, seismic retrofitting does not lend itself to straightforward codified procedures or cook-book approaches. As such, seismic evaluation and rehabilitation need the best that the current state-of-the-art can offer on all aspects of earthquake engineering. This volume serves this need, as it gathers the most recent research of top seismic experts from around the world on seismic evaluation, retrofitting and closely related subjects.

Download or read book Protection of Built Environment Against Earthquakes written by Matjaž Dolšek and published by Springer Science & Business Media. This book was released on 2011-08-16 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current knowledge and state-of-the-art developments in topics related to the seismic performance and risk assessment of different types of structures and building stock are addressed in the book, with emphasis on probabilistic methods. The first part addresses the global risk components, as well as seismic hazard and ground motions, whereas the second, more extensive part presents recent advances in methods and tools for the seismic performance and risk assessment of structures. The book contains examples of steel, masonry and reinforced concrete buildings, as well as some examples related to various types of infrastructure, such as bridges and concrete gravity dams. The book's aim is to make a contribution towards the mitigation of seismic risk by presenting advanced methods and tools which can be used to achieve well-informed decision-making, this being the key element for the future protection of the built environment against earthquakes. Audience: This book will be of interest to researchers, postgraduate students and practicing engineers working in the fields of natural hazards, earthquake, structural and geotechnical engineering, and computational mechanics, but it may also be attractive to other experts working in the fields related to social and economic impact of earthquakes.

Download or read book Evaluation of the Factors Influencing the Seismic Demand on Non structural Elements written by Giulia Scagliotti and published by . This book was released on 2022 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This work focuses on the seismic design of non-structural components, which are elements attached to the floors, roof and walls of a building and are not part of the main structural system. During seismic events, damage to these critically important elements may be extensive, costly and even life threatening. Current building codes that provide design criteria and requirements for non-structural elements follow a simplified prescriptive approach and do not take into account some relevant parameters. Hence, the goal of this work is to examine the factors that influence the seismic demand on acceleration-sensitive non-structural components, evaluate current design criteria and suggest improved requirements with the aim to reduce their level of damage in case of an earthquake. Specifically, the research involves processing and interpretation of strong motion acceleration data, which has been recorded in instrumented buildings in California that have experienced earthquake ground shaking. This work highlights the relevance of building periods and ground motion frequency content in determining the seismic demand on non-structural elements. Furthermore, it shows the role played by the relationship between the natural period of the non-structural component and the vibration modes of the building on the component amplification. Including these factors into the building code design criteria for non-structural elements would better predict the seismic demand on non-structural elements, and it follows that design to the improved demand estimates would reduce earthquake damage to non-structural elements.

Download or read book Seismic Design and Assessment of Bridges written by Andreas J. Kappos and published by Springer Science & Business Media. This book was released on 2012-04-18 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book focuses on the use of inelastic analysis methods for the seismic assessment and design of bridges, for which the work carried out so far, albeit interesting and useful, is nevertheless clearly less than that for buildings. Although some valuable literature on the subject is currently available, the most advanced inelastic analysis methods that emerged during the last decade are currently found only in the specialised research-oriented literature, such as technical journals and conference proceedings. Hence the key objective of this book is two-fold, first to present all important methods belonging to the aforementioned category in a uniform and sufficient for their understanding and implementation length, and to provide also a critical perspective on them by including selected case-studies wherein more than one methods are applied to a specific bridge and by offering some critical comments on the limitations of the individual methods and on their relative efficiency. The book should be a valuable tool for both researchers and practicing engineers dealing with seismic design and assessment of bridges, by both making the methods and the analytical tools available for their implementation, and by assisting them to select the method that best suits the individual bridge projects that each engineer and/or researcher faces.

Download or read book Seismic Analysis and Design using the Endurance Time Method written by Homayoon E. Estekanchi and published by CRC Press. This book was released on 2021-10-08 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The endurance time method (ETM) is a seismic analysis procedure in which intensifying dynamic excitations are used as the loading function, and it provides many unique benefits in the design of structures. It can largely reduce the computational effort needed for the response history analysis of structures. This aids in the practical application of response history-based analysis in problems involving very large models and/or requiring numerous analyses to achieve optimal design goals. A single response history analysis through ETM provides an estimate of the system response at the entire range of seismic intensities of interest, thus making it ideal for applications such as seismic risk assessment, life-cycle cost analysis, and value-based seismic design. Conceptual simplicity also makes ETM a useful tool for preliminary response history analysis of structural systems. Features: Presents full coverage of the subject from basic concepts to advanced applied topics. Provides a coherent text on endurance time excitation functions that are essential in endurance time analysis. Seismic Analysis and Design using the Endurance Time Method serves as a comprehensive resource for students, researchers, and practicing structural engineers who want to familiarize themselves with the concepts and applications of the endurance time method (ETM) as a useful tool for dynamic structural analysis.
