This book was released on 2014-06-19 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: SYNER-G, a multidisciplinary effort funded by the European Union, allowed the development of an innovative methodological framework for the assessment of physical as well as socio-economic seismic vulnerability and risk at urban and regional level. The results of SYNER-G are presented in two books both published by Springer, the present and a second one, entitled “SYNER-G: Typology Definition and Fragility Functions for Physical Elements at Seismic Risk: Buildings, Lifelines, Transportation Networks and Critical Facilities”(*), which provides a comprehensive state-of-the-art of the fragility curves, an alternative way to express physical vulnerability of elements at risk. In this second volume of SYNER-G, the focus has been on presenting a unified holistic methodology for assessing vulnerability at systems level considering interactions between elements at risk (physical and non-physical) and between different systems. The proposed methodology and tool encompasses in an integrated fashion all aspects in the chain, from hazard to the vulnerability assessment of components and systems and to the socio-economic impacts of an earthquake, accounting for most relevant uncertainties within an efficient quantitative simulation scheme. It systematically integrates the most advanced fragility functions to assess the vulnerability of physical assets for buildings, utility systems, transportation networks and complex infrastructures such as harbours and hospitals. The increasing impact due to interactions between different components and systems is treated in a comprehensive way, providing specifications for each network and infrastructure. The proposed socio-economic model integrates social vulnerability into the physical systems modelling approaches providing to decision makers with a dynamic platform to capture post disaster emergency issues like shelter demand and health impact decisions. Application examples at city and regional scale have provided the necessary validation of the methodology and are also included in the book. The present volume, with its companion volume on fragility functions, represent a significant step forward in the seismic vulnerability and risk assessment of complex interacting urban and regional systems and infrastructures. These volumes are not only of interest to scientists and engineers but also to the insurance industry, decision makers and practitioners in the sector of civil protection and seismic risk management.

Download or read book Acceptable Risk Processes written by Craig Taylor and published by ASCE Publications. This book was released on 2002-01-01 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prepared by the Council on Disaster Reduction and the Technical Council on Lifeline Earthquake Engineering of ASCE. This TCLEE Monograph provides engineers and decision makers with tools to help them better understand acceptable risk processes and then develop risk reduction strategies and implement mitigation actions to reduce lifeline losses from future earthquakes. The disruption of lifelines from natural hazards has a direct impact on the world's regional economies and the health of their citizens. Therefore, it is important to understand what natural hazards are, how they can affect infrastructure lifelines, and what can be done to minimize their impact. These three elements, in turn, influence decisions that involve acceptable risk processes. The topic of "acceptable risk" provides one way of bringing integrated systems risk evaluations for disaster explicitly into a decision-making context. Topics include technical issues; risk criteria issues; and communication, administration, and regulation issues.

Available in PDF, EPUB and Kindle. Book excerpt: Transportation networks constitute one class of major civil infrastructure systems that is a critical backbone of modern society. Physical damage and functional loss to transportation infrastructure systems not only hinder everyday societal and commercial activities, but also impair post-disaster response and recovery, leading to substantial socio-economic consequences. Therefore, understanding and modeling the disastrous impact on the transportation infrastructures and the corresponding changes of travel patterns under extreme events are vital for stakeholders, emergency managers, and government agencies to mitigate, prepare for, respond to, and recover from the potential impact. This research is aimed at developing a systematic approach for risk modeling and disaster management of transportation systems in the context of earthquake engineering. First, by employing the performance metrics that are suited for immediate post-disaster response, this dissertation explores efficient methodologies to maximize the overall system functionality and the benefit of mitigation investment for transportation infrastructure systems. Furthermore, the regions potentially unreachable after a damaging earthquake are identified promptly by using network reachability algorithms that provide essential information for rapid emergency response decision-making. Lastly, an integrated simulation model of travel demand that accounts for damage of bridge and building structures, release of hazardous materials, and influences of emergency shelters and hospitals, is developed to approximate the 0́−abnormal0́+ post-earthquake travel patterns and evaluate the functional loss of the transportation systems. This study extends the understanding of disaster management of transportation infrastructure systems. The methodologies developed in this study have the following significance: (i) help leverage available mitigation resources to improve the disaster resilience and functionality of transportation infrastructure systems; (ii) enable emergency response and recovery teams to rapidly identify and evaluate the performance of optimal routes for emergency ingress and egress; (iii) accurately estimate traffic congestion under extreme events; and (iv) provide important insights necessary to make decisions on protecting these systems to meet the needs of current and future generations.

Available in PDF, EPUB and Kindle. Book excerpt: Water distribution systems are vital to the well-being of communities because they contribute to the functionality of all other infrastructure and lifeline systems. Earthquakes and other natural hazards can cause damage to the components of a water distribution system, causing far-reaching socioeconomic consequences. This research begins with the development of an end-to-end simulation framework to model post-earthquake functional loss and restoration of a water system, which encompasses seismic hazard characterization, component damage assessment, hydraulic performance evaluation, and network restoration modeling. The modeling framework is validated using data from the 2014 South Napa Earthquake and extended to a hypothetical scenario. The end-to-end simulation framework is then extended to consider stochastic event set assessments of the water network using the UCERF2 (Uniform California Earthquake Rupture Forecast, Version 2) earthquake rupture forecast model. Given that the end-to-end performance evaluation of distributed infrastructure for a large set of events is computationally expensive, a framework that uses Active learning to select a subset of ground motion maps and associated occurrence rates that reasonably estimates the water network risk is also developed. To deal with the temporal complexities that are embedded in the post-earthquake restoration process, a dynamic updating methodology is developed to reduce uncertainties in the outcomes of post-event recovery forecasts using Bayesian Inferencing, by exploiting real-time data. The specific example of updating predictions (post-earthquake functional recovery forecasts including total recovery time and complete recovery trajectory) is presented and validated on a real pipe network (Napa water system) and event (2014 earthquake and recovery). Ultimately, the frameworks and models developed as part of this work can inform risk-based decision making and resilience planning of water networks and other lifeline systems.

We deployed a web-based survey for the Texas 2021 winter storm and built statistical models to investigate the effects of household and event attributes, household risk experience and perception, and social connectedness on household impact and adaptation adoption. The results from this study were compared to findings from Los Angeles (both revealed and stated preferences) studies to explore the patterns and generalizability of the results. The findings revealed a similar frequency of implemented adaptations to those in Los Angeles, but predictors of adaption and the household impact that were somewhat different. These findings provide insight to comprehend the degree of societal impact and adaptation adoption due to service interruptions, which facilitates efficient emergency management.

Download or read book Improved Treatment of Epistemic Uncertainty in Seismic Hazard Modeling with Focus on Central and Eastern North America written by Ali Farhadi and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, I take advantage of up-to-date studies and recently compiled datasets to solve some important problems faced in seismic hazard modeling in the Central and Eastern North America (CENA) as well as in Iran through four separate chapters. In these chapters, I provide useful information to improve treatment of epistemic uncertainty in seismic hazard modeling for CENA and Iran. Seismic hazard modelers in both CENA and Iran may use this study when performing earthquake hazard evaluations. In the first chapter, I assess the applicability of ground-motion models (GMMs) to propose a set of models that can be confidently used for induced seismicity applications within the CENA. This study is the first or one of the earliest studies of this kind that focused on GMMs for induced earthquakes. In the second chapter, I use the same methodology to come up with a shortlist of suitable GMMs for the probabilistic seismic hazard assessment (PSHA) in Iran. The need for assessing models relative performances prior to carrying out seismic hazard studies is crucial for the tectonic region of Iran due to the shortage of experienced domestic experts. In the last two chapters, because of the need of the earthquake engineering community in CENA to predict ground-motion intensity measures (GMIMs) other than the horizontal ground-motion component, I develop a set of new GMMs based on the NGA-East database. I develop these models using the referenced empirical approach. In the third chapter of the present study, I establish a referenced empirical ground-motion model for estimating Arias Intensity (AI) and cumulative absolute velocity (CAV) for CENA using Campbell and Bozorgnia (2019) as the reference model. AI and CAV have extensive applications in assessing the impact of strong-motion duration on slope stability, soil liquefaction, building damage, and seismic response of bridges. In the fourth chapter, I develop three referenced empirical models considering the Bozorgnia and Campbell (2016), Glerce et al. (2017), and Stewart et al. (2016) models. The effect of the vertical component is significant for the design of ordinary highway bridges and vital structures such as nuclear power plants and dams..

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Earthquakes in the last 100 years have resulted in $3 trillion U.S. dollars in economic losses worldwide. Even moderate-magnitude events, such as the Mw6.7 1994 Northridge earthquake and the Mw6.9 1989 Loma Prieta earthquake, have caused widespread damage, significant economic losses, and tens of thousands of families displaced from their homes. In the last two decades, the performance-based earthquake engineering framework developed by the Pacific Earthquake Engineering Research Center, also referred to as the PEER PBEE framework, has gained much attention from researchers and practitioners not only in the U.S. but also in most seismic-prone countries. This framework was focused on individual structures under seismic hazards. However, large earthquakes occurring close to large urban regions may strike and affect thousands or even millions of structures simultaneously, leading to large numbers of casualties and significant disruptions to the normal functionality of communities. Hence, the concept of "performance" in PBEE needs to be expanded from an individual to a regional scale, with broader definitions of stakeholders and performance metrics in order to evaluate the seismic risk of groups of structures that are spatially distributed within a region, referred to as regional seismic risk. The main goal of this dissertation is to propose improved regional seismic risk methodologies within a probabilistic framework that explicitly quantifies, incorporates, and propagates uncertainties at the different stages of the analysis, in order to provide improved information for decision makers. The main contributions of this dissertation are: • A mathematical formalization of a regional performance-based earthquake engineering (RPBEE) framework for seismic risk assessment of groups of structures and infrastructure spatially distributed within a region. • An improved model for the spatial correlation of ground motion intensity measures, which is based on 39 well-recorded earthquakes and is the first model that explicitly incorporates the event-to-event variability. • Recommendations of ground motion intensity measures to characterize the seismic hazard for regional seismic risk assessment of wood-frame single-family houses. • An investigation on the relative seismic performance of one- and two-story houses, leading to recommendations for future building classification systems for regional seismic risk assessment, where one- and two-story houses are separated into different classes with different seismic vulnerabilities. • Novel fragility curves for estimating the probability of damage to chimneys and severe damage to structural shear walls in wood-frame single-family houses which are particularly useful for improving current approaches to estimate the number of yellow- and red-tagged wood-frame single-family houses. • A model for explicitly incorporating the correlation between the damage in different structures conditioned on their ground motion intensities for regional seismic risk asessment, along with an investigation on the effect of this correlation on regional seismic risk metrics. • A probabilistic framework for evaluating and comparing alternative public policies for enhancing the seismic performance of structures in terms of regional seismic risk mitigation. • Evaluation of the inherent regional risk of collapse implicit with the probability of collapse of individual buildings that is currently specified as acceptable in U.S. seismic design provisions. • A simplified seismic design approach that explicitly considers the regional seismic risk in the seismic design criteria of structures, referred to as "regional-risk-targeted seismic design.".

This book was released on 2012-05-31 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the past few years, there has been extensive research done on structural design in terms of optimization methods or problem formulation. But, much of this attention has been on the linear elastic structural behavior, under static loading condition. Such a focus has left researchers scratching their heads as it has led to vulnerable structural configurations. What researchers have left out of the equation is the element of seismic loading. It is essential for researchers to take this into account in order to develop earthquake resistant real-world structures. Structural Seismic Design Optimization and Earthquake Engineering: Formulations and Applications focuses on the research around earthquake engineering, in particular, the field of implementation of optimization algorithms in earthquake engineering problems. Topics discussed within this book include, but are not limited to, simulation issues for the accurate prediction of the seismic response of structures, design optimization procedures, soft computing applications, and other important advancements in seismic analysis and design where optimization algorithms can be implemented. Readers will discover that this book provides relevant theoretical frameworks in order to enhance their learning on earthquake engineering as it deals with the latest research findings and their practical implementations, as well as new formulations and solutions.
