Available in PDF, EPUB and Kindle. Book excerpt: Earthquake is one of the most destructive natural disasters leading to financial, environmental, and even human losses. The most effective approach to prevent losses induced by structural damage is seismic design for structures, in which the determination of design earthquakes, including seismic design spectra and seismic design ground motions, is of great importance. Probabilistic Seismic Hazard Analysis (PSHA) has been widely used for the determination and selection of design earthquakes. However, there are a number of issues on the engineering application of PSHA in obtaining the design earthquakes, which need to be addressed before it can be readily implemented into reliability- and performance-based seismic design. In this research, based on the PSHA, the generation of seismic design spectra and spectrum-compatible earthquake groundmotions is studied. The PSHA-based seismic design spectra mainly include Uniform Hazard Spectrum (UHS), predicted spectrum based on Ground-Motion Prediction Equations (GMPEs), and Conditional Mean Spectrum considering [epsilon] (CMS-[epsilon]). These existing design spectra, however, do not or only partially provide probabilistic knowledge about the simultaneous occurrence of spectral accelerations at multiple vibration periods. The lack of such probabilistic knowledge of the design spectra may prevent them from being incorporated into reliability- and performance-based seismic design. The purpose of this study is to bridge the gaps between seismological analyses and engineering applications, i.e., to find suitable representations of design earthquakes from the PSHA.

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 Simplified Vector-valued Probabilistic Seismic Hazard Analysis and Probabilistic Seismic Demand Analysis by : André R. Barbosa
Download or read book Simplified Vector-valued Probabilistic Seismic Hazard Analysis and Probabilistic Seismic Demand Analysis written by André R. Barbosa and published by . This book was released on 2011 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive and rigorous probabilistic methodology for performance-based earthquake engineering (PBEE) has been under development under the auspice of the Pacific Earthquake Engineering Research (PEER) Center over the past thirteen years. The probabilistic estimation of the seismic demand is an important part of the PBEE methodology and consists of a two-step procedure: probabilistic seismic hazard analysis (PSHA), and probabilistic seismic demand analysis (PSDA). Two shortcomings are identified in past applications of the PBEE methodology : (i) the use of a single, or scalar, ground motion intensity measure (IM) which is typically taken as the 5% damped linear spectral acceleration, Sa(T1), at the fundamental period of the structure; and (ii) the use of testbed applications based on two-dimensional (2-D) finite element (FE) models (e.g., 2-D frame models) of the considered structures, which are three-dimensional in nature and cannot always be reduced to 2-D models. Sa(T1) represents an inefficient and insufficient predictor of the nonlinear structural response for structures with significant higher mode effects and significantly different fundamental periods in two orthogonal directions. This dissertation addresses both shortcomings. First, a simplified and computationally efficient vector-valued PSHA (VPSHA), making use of USGS scalar probabilistic seismic hazard maps results, is proposed. Second, a PSDA of an advanced 3-D nonlinear FE model of the 13-story National Earthquake Hazards Reduction Program (NEHRP) reinforced-concrete frame-wall building design example is performed based on the simplified VPSHA for a specific site located in Berkeley, California. Nonlinear dynamic time-history analyses (NDTHA) are performed by subjecting the 3-D nonlinear FE model to an ensemble of 90 bi-directional (horizontal) historical earthquake ground motions. The FE model was developed in OpenSees and results of the FE analyses are used to establish a statistical model between the IMs and different EDPs (e.g., roof drift ratio, interstory drift ratios, and floor absolute accelerations). Based on the computational results from NDTHA, it is found that, for the building structure considered, a vector-valued IM consisting of multiple spectral accelerations at different periods of interest is a sufficient and more efficient predictor of the structural response, and therefore provides for more reliable and mode accurate PSDA results.

Book Synopsis Advanced Seismic Hazard Assessment by : Giuliano Panza
Download or read book Advanced Seismic Hazard Assessment written by Giuliano Panza and published by Birkhäuser. This book was released on 2011-05-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Issues pertaining to urban risks are a pressing concern for those involved in disasters mitigation. Development of effective mitigation strategies requires sound seismic hazard information that is commonly derived through a seismic hazard assessment (SHA). The purpose of SHA is to provide a scientifically consistent estimate of seismic hazard for engineering design and other considerations. The time is ripe to move beyond the old paradigms of the traditional Probabilistic Seismic Hazard Analysis (PSHA). This two-part volume advocates advanced methods for SHA that utilize up to date earthquake science and basic scientific principles to derive the seismic hazard in terms of a ground motion or related quantity and its occurrence frequency at a site, as well as the associated uncertainty. It aims to: (1) identify the issues in the current SHAs, (2) facilitate the development of a scientifically consistent approach for SHA and (3) disseminate, both in scientific and in engineering practice societies, advanced reliable tools for independent hazard estimates, like NDSHA (neo-deterministic SHA), which incorporates physically based ground motion models. It provides a fresh approach to seismic hazard analysis. Part 2 provides advanced SHA case studies, concerning regional national and metropolitan estimates for different parts of the world, including Asia, Europe, North and South America. It is addressed to seismologists, engineers and stake-holders, and aims to contribute to bridging between modern interdisciplinary research and practitioners.

Download or read book Characterization of Modern and Historical Seismic–Tsunamic Events, and Their Global–Societal Impacts written by Y. Dilek and published by Geological Society of London. This book was released on 2021-06-22 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earthquakes and tsunamis are devastating geohazards with significant societal impacts. Most recent occurrences have shown that their impact on the stability of nations–societies and the world geopolitics is immense, potentially triggering a tipping point for a major downturn in the global economy. This Special Publication presents the most current information on the causes and effects of some of the modern and historical earthquake–tsunami events, and effective practices of risk assessment–disaster management, implemented by various governments, international organizations and intergovernmental agencies. Findings reported here show that the magnitude of human casualties and property loss resulting from earthquakes–tsunamis are highly variable around the globe, and that increased community, national and global resilience is significant to empower societal preparedness for such geohazards. It is clear that all stakeholders, including scientists, policymakers, governments, media and world organizations must work together to disseminate accurate, objective and timely information on geohazards, and to develop effective legislation for risk reduction and realistic hazard mitigation–management measures in our globally connected world of today.
Book Synopsis Guidelines for Probabilistic Performance-Based Seismic Design and Assessment of Slope Engineering by : Yu Huang
Download or read book Guidelines for Probabilistic Performance-Based Seismic Design and Assessment of Slope Engineering written by Yu Huang and published by Springer Nature. This book was released on 2023-03-16 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a new design and evaluation framework based on slope Stochastic Dynamics theory to probabilistic seismic performance for slope engineering. For the seismic dynamic stability safety of slope, it shifts from deterministic seismic dynamic analysis to quantitative analysis based on nonlinear stochastic dynamics, that is, from qualitative to the description of stochasticity of earthquake excitation that meet the needs in related design specification and establish a performance standard. In the nonlinear dynamic time history analysis of slope subjected to seismic ground motion, the term “randomness” is used to express the uncertainty in the intensity and frequency of earthquake excitation for slope engineering dynamic seismic performance. It mainly includes seismic design fortification standard, corresponding ground motion excitation, performance index threshold, and slope deterministic nonlinear seismic dynamic response. Even more than that, the seismic dynamic large deformation approaches of the whole process and comprehensive analysis for flow analysis after slope instability failure. Eventually, the probabilistic seismic dynamic performance of the slope engineering will be characterized by nonlinear dynamic reliability.
