Download or read book Performance Based Aseismic Design of Shallow Foundations written by Jeremy Toh and published by LAP Lambert Academic Publishing. This book was released on 2010-07 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: State of the art understanding of the seismic behaviour of shallow foundations has advanced rapidly in recent years, yet current design practice does not account for these advances. The idea that shallow foundation bearing failure should not occur during an earthquake is not in line with other areas of earthquake engineering, where performance based design is widely accepted. The macro-element investigated in this study is a simple tool that can model complex dynamic soil-structure interaction beneath a shallow foundation. A detailed account of macro-element theory and behaviour is given and a computer code, written for use with the MATLAB software, is included. Insights are made into the usefulness of the macro-element in routine design, the trade-off between actions and permanent displacements of the foundation and superstructure, and the way that conventional geotechnical conservatism does not apply in performance based design. This book will be of interest to academics and practitioners involved in earthquake engineering. It will be of particular value to those working in the areas of performance based design and soil-foundation-structure interaction.

Book Synopsis Probabilistic performance-based seismic design by : fib Fédération internationale du béton
Download or read book Probabilistic performance-based seismic design written by fib Fédération internationale du béton and published by fib Fédération internationale du béton. This book was released on 2012-05-07 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last ten to fifteen years a vast amount of research has been undertaken to improve on earlier methods for analysing the seismic reliability of structures. These efforts focused on identifying aspects of prominent relevance and disregarding the inessential ones, with the goal of producing methods that are both more efficient and easier to use in practice. Today this goal can be said to be substantially achieved. During these years scientific activity covered all of the many aspects involved in such a multi-disciplinary problem, ranging from seismology, to geotechnics, to structural analysis and economy, all of them to be consistently organised into a probabilistic framework. As the output of this research was dispersed into a multitude of technical papers, fib Commission 7 thought it worthwhile to select the essential aspects of this large body of knowledge and to present them into a coherent and accessible document for structural engineers. To this end a task group of specialists was formed, whose qualifications come from their personal involvement in the above-mentioned developments throughout this period of time. From its inception the group decided that the bulletin should have had a distinct educational character and provide a clear overview of the methods available. The outcome is a compact volume that starts by introducing the concepts and definitions of performance-based engineering, continues with two chapters on assessment and design, respectively, presenting the methods in detail accompanied by illustrative examples, and concludes with an appendix with sample programming excerpts for their implementation. It is believed that at present fib Bulletin 68 represents a unique compendium on probabilistic performance-based seismic design.

Book Synopsis Performance Based Seismic Design for Tall Buildings by : Ramin Golesorkhi
Download or read book Performance Based Seismic Design for Tall Buildings written by Ramin Golesorkhi and published by . This book was released on 2017-10-30 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Performance-Based Seismic Design (PBSD) is a structural design methodology that has become more common in urban centers around the world, particularly for the design of high-rise buildings. The primary benefit of PBSD is that it substantiates exceptions to prescribed code requirements, such as height limits applied to specific structural systems, and allows project teams to demonstrate higher performance levels for structures during a seismic event.However, the methodology also involves significantly more effort in the analysis and design stages, with verification of building performance required at multiple seismic demand levels using Nonlinear Response History Analysis (NRHA). The design process also requires substantial knowledge of overall building performance and analytical modeling, in order to proportion and detail structural systems to meet specific performance objectives.This CTBUH Technical Guide provides structural engineers, developers, and contractors with a general understanding of the PBSD process by presenting case studies that demonstrate the issues commonly encountered when using the methodology, along with their corresponding solutions. The guide also provides references to the latest industry guidelines, as applied in the western United States, with the goal of disseminating these methods to an international audience for the advancement and expansion of PBSD principles worldwide.

Book Synopsis Seismic Performance of Soil-Foundation-Structure Systems by : Nawawi Chouw
Download or read book Seismic Performance of Soil-Foundation-Structure Systems written by Nawawi Chouw and published by CRC Press. This book was released on 2017-08-25 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seismic Performance of Soil-Foundation-Structure Systems presents invited papers presented at the international workshop (University of Auckland, New Zealand, 21-22 November 2016). This international workshop brought together outstanding work in earthquake engineering that embraces a holistic consideration of soilfoundation-structure systems. For example, the diversity of papers in this volume is represented by contributions from the fields of shallow foundation in liquefiable soil, spatially distributed lifelines, bridges, clustered structures (see photo on front cover), sea floor seismic motion, multi-axial ground excitation, deep foundations, soil-foundation-structurefluid interaction, liquefaction-induced settlement and uplift with SFSI. A fundamental knowledge gap is manifested by the isolated manner geotechnical and structural engineers work. A holistic consideration of soil-foundation-structures systems is only possible if civil engineers work collaboratively to the mutual benefit of all disciplines. Another gap occurs by the retarded application of up-to-date research findings in engineering design practices. Seismic Performance of Soil-Foundation-Structure Systems is the outcome from the recognized need to close this gap, since it has been observed that a considerable delay exists between published research findings and application of the principles revealed by the research. Seismic Performance of Soil-Foundation-Structure Systems will be helpful in developing more understanding of the complex nature of responses these systems present under strong earthquakes, and will assist engineers in closing the gaps identified above.
Book Synopsis Earthquake Geotechnical Engineering Design by : Michele Maugeri
Download or read book Earthquake Geotechnical Engineering Design written by Michele Maugeri and published by Springer Science & Business Media. This book was released on 2014-02-03 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pseudo-static analysis is still the most-used method to assess the stability of geotechnical systems that are exposed to earthquake forces. However, this method does not provide any information about the deformations and permanent displacements induced by seismic activity. Moreover, it is questionable to use this approach when geotechnical systems are affected by frequent and rare seismic events. Incidentally, the peak ground acceleration has increased from 0.2-0.3 g in the seventies to the current value of 0.6-0.8 g. Therefore, a shift from the pseudo-static approach to performance-based analysis is needed. Over the past five years considerable progress has been made in Earthquake Geotechnical Engineering Design (EGED). The most recent advances are presented in this book in 6 parts. The evaluation of the site amplification is covered in Part I of the book. In Part II the evaluation of the soil foundation stability against natural slope failure and liquefaction is treated. In the following 3 Parts of the book the EGED for different geotechnical systems is presented as follows: the design of levees and dams including natural slopes in Part III; the design of foundations and soil structure interaction analysis in Part IV; underground structures in Part V. Finally in Part VI, new topics like the design of reinforced earth retaining walls and landfills are covered.
Book Synopsis Isolated shallow rocking foundation on different soils with varying embedment depth by :
Download or read book Isolated shallow rocking foundation on different soils with varying embedment depth written by and published by OAE Publishing Inc.. This book was released on 2024-01-29 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although seismic design concepts integrated the idea of shallow rocking foundations as an effective way to dissipate the induced seismic energy, a practical design solution is yet to be established. To attain this objective, it is necessary to identify the key parameters that govern the rocking efficacy of foundation and eventually overall seismic performance of the entire structure. The primary focus of this study is to assess the key parameters such as soil type and embedment depth of footing in conjunction with varying rocking foundation efficacy on the seismic force and displacement demands of the Reinforced Concrete (RC) buildings. A simplified generic high rise RC building along with its foundation is considered for the analytical study which is designed and detailed as per relevant Indian Standards. To highlight the beneficial effects of rocking foundation, seismic responses of the RC buildings with varying foundation rocking efficacy are compared with the conventional foundation design philosophies by conducting nonlinear dynamic time history analyses. From the seismic responses, it is determined that the moment from column to foundation and base shear, owing to seismic action, decreases with an increasing settlement at the base of the foundation for rocking footing. It is also observed from the seismic responses that rocking foundations effectively de-amplifies the peak roof acceleration by utilizing the nonlinear soil responses during earthquakes. Hence, it can be depicted that the foundation rocking improves the overall stability of the buildings by decreasing the seismic force demands with a slight increase in seismic displacement demands. The investigation also indicates that the efficacy of rocking foundation is not sensitive to embedment depth of footing.
