Available in PDF, EPUB and Kindle. Book excerpt: Recent earthquake disasters have demonstrated the seismic vulnerability of highway bridge systems. Rapid seismic assessment of regional highway bridges is critical to help reduce severe loss of life and property. However, measurement of the regional scale system performance faces the challenge of dealing with the large uncertainty in structural properties and spatial characteristics. Traditionally, the numerical modeling approaches are established to simulate nonlinear response for each highway bridge across a regional portfolio. This process is largely limited by accuracy of model and computational effort. Especially some key structural component parameters are almost impossible to be retrieved for some ancient bridges. An alternative data-driven framework is developed to predict seismic responses or damage level of bridges using machine learning techniques. The proposed hierarchically structured framework enables a customized application in different scenarios. Firstly, the typical modeling technique for reinforcement concrete highway bridges is introduced using specific elements for different components. However, the modeling procedures are material-level parameter dependent and time consuming. The nonlinear analysis convergence is also a frustrating problem for numerical simulations. Due to these realistic limitations, a simple, fast and robust numerical model which can be developed with only component-level information needs to be adopted. It's shown that the bridge bent representation can be simplified as a single degree of freedom system. The force-displacement relationship of the bridge can be roughly approximated by a bilinear curve. So a simplified 2D bilinear model is adopted for highway bridges throughout the study. Secondly, the statistical distributions for selected bridge input parameters can be derived based on the regional bridge inventory. Then an iterative process by sampling and filtering input parameters can be used to generate as many bridges as possible candidates for a specific region. The proposed bridge models and selected historical ground motions will be utilized to develop a seismic response prediction model using machine learning for instrumented highway bridges. This study investigates the optimal features to represent the highway bridge and ground motion. Different regression models are applied for near-fault motions and far-field motions and similar performance can be achieved, which significantly outperformed the traditional methods. Finally, to predict the seismic response of the non-instrumented highway bridges whose ground motion information is missing, the kriging interpolation model is implemented first. Then graph network is exploited to improve the performance. Different rules are evaluated for constructing an undirected graph for the highway bridges in an active seismic region. Subsequently, the Node2vec model is conducted to extract the embedding for each node and a graph neural network is implemented to predict the seismic response. Furthermore, vast amounts of text description data from online social platforms can be used to help detect the potential severely damaged bridges rapidly once an earthquake happens. A Convolution Neural Network classification model is implemented to evaluate the overall damage level distribution based on the collected text data. GloVe model is used to generate the word vector as its distributed representation.

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Like the systems that supply residents of an area with power, water, sanitation, and communication services, road networks, which provide transport, are lifelines (Chang, 2016). Earthquakes can result in extensive damage to road networks and, in California, have historically caused significant damage to bridges (Mitchell et al., 1995). The immediate goal of seismically retrofitting a bridge is to mitigate the risk of the bridge experiencing structural damage during an earthquake (e.g., Buckle et al., 2006). Seismically retrofitting a bridge reduces the probability that it will be damaged by ground shaking in an earthquake -- and, consequently, the probability that it will incur repair costs or contribute to the indirect costs associated with road network disruptions. Retrofitting bridges has been shown to be a cost-effective method of mitigating the risk of bridge damage (e.g., Giovinazzi et al., 2011). Given budget constraints, retrofitting every bridge in a regional road network subject to seismic hazard is infeasible. How to decide which bridges within such a network to retrofit has therefore proven to be a problem of enduring interest. Complicating factors include the scale of the real-world problem, which precludes exhaustive searches, uncertainty in the seismic hazard and associated bridge damage, the link between bridges' states and the performance of the road network, and the computational cost of simulating road network performance. This dissertation proposes probabilistic and computationally tractable methods for performance-based seismic risk mitigation of complex regional road networks. First, this dissertation proposes a method for prioritizing bridge retrofits within a regional road network subject to uncertain seismic hazard, using a technique that accounts for network performance while avoiding the combinatoric costs of exhaustive searches. Using global variance-based sensitivity analysis (SA), bridges are ranked according to how much their retrofit statuses influence the expected cost of road network disruption, as measured by their total-order sensitivity (Sobol') indices. In a case study of 71 bridges in San Francisco, the proposed method identifies more effective retrofits than other heuristic retrofit prioritization strategies. The proposed method also remains computationally tractable while accounting for uncertainty in the seismic hazard, the stochastic nature of bridge damage, the uniqueness of individual bridges, network effects, and decision-makers' priorities, including budget considerations (but not constraints). As this method leverages existing risk assessment tools and models without imposing further assumptions, it should be extensible to other types of networks, hazards, and decision variables. Second, this dissertation proposes a method with which to increase the computational tractability of the SA-based bridge retrofit prioritization method when the decision variable of interest requires traffic simulation. To more efficiently compute bridges' Sobol' indices, a neural network is trained to serve as a surrogate model for a traffic simulator. For the same set of 71 bridges in San Francisco previously studied, a retrofit strategy based on bridges' total-order Sobol' indices computed using the surrogate model agrees closely with a strategy based on indices computed using only the traffic simulator while reducing the computational time required by as much as 99%. A surrogate model-based approach is also effective at prioritizing bridge retrofits for a set of 141 highway bridges in two Bay Area counties. Leveraging the power of surrogate models to reduce the computational burden of estimating bridges' total-order Sobol' indices will allow application of the SA-based retrofit prioritization method to larger numbers of bridges and larger sets of earthquake scenarios. It will also enable the use of more sophisticated traffic models to characterize network performance. Third, this dissertation integrates two measures of how post-earthquake road network disruption impacts individuals with a probabilistic seismic risk assessment framework in a computationally tractable way. Impacts on individual commuters are characterized using welfare loss, which is a measure of individual well-being and was previously formulated by Mackie et al. (2001), and the number of jobs affected by road network disruption, a novel measure. A case study of the San Francisco Bay Area shows that while all commuters have a similar risk of increased travel time due to post-earthquake road network disruption, commuters with low incomes have substantially higher risk of welfare loss than commuters with high incomes. Traditional metrics of road network disruption like travel time delay, infeasible trips, or combinations thereof obscure these disparate impacts. Quantitative risk metrics that account for variations in individuals' experiences without becoming computationally impracticable should prove useful in reducing risk to regional infrastructure networks in more equitable ways. A novel method for modifying post-earthquake commute demand to account for business interruptions is also presented. This method allows us to better distinguish between the impacts of road network disruption and the impacts of building damage on workers in a region, which is necessary to design effective risk reduction policies. Lastly, this dissertation includes a study of earthquake responders' building damage information needs and use. Although many responders need to understand the scale and distribution of building damage to react effectively, their building damage information needs and information use remain poorly understood, limiting the efficacy of information production, sharing, and research. Based on interview data and questionnaire responses gathered from experienced responders, six post-disaster tasks that rely on building damage information are characterized by their timing and by the necessary qualities of the information they require. Through inductive analysis of the interview data, responders' use of building damage information is also found to depend on factors beyond the building damage information itself -- namely, trust, impediments to information sharing, their varying understandings of disaster, and their attitudes toward emerging technologies. These factors must be considered in the design of any effort to create and/or disseminate post-disaster building damage information.

Download or read book Next Generation Seismic Fragility Curves for California Bridges Incorporating the Evolution in Seismic Design Philosophy written by Karthik Narayan Ramanathan and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantitative and qualitative assessment of the seismic risk to highway bridges is crucial in pre-earthquake planning, and post-earthquake response of transportation systems. Such assessments provide valuable knowledge about a number of principal effects of earthquakes such as traffic disruption of the overall highway system, impact on the regions' economy and post-earthquake response and recovery, and more recently serve as measures to quantify resilience. Unlike previous work, this study captures unique bridge design attributes specific to California bridge classes along with their evolution over three significant design eras, separated by the historic 1971 San Fernando and 1989 Loma Prieta earthquakes (these events affected changes in bridge seismic design philosophy). This research developed next-generation fragility curves for four multispan concrete bridge classes by synthesizing new knowledge and emerging modeling capabilities, and by closely coordinating new and ongoing national research initiatives with expertise from bridge designers. A multi-phase framework was developed for generating fragility curves, which provides decision makers with essential tools for emergency response, design, planning, policy support, and maximizing investments in bridge retrofit. This framework encompasses generational changes in bridge design and construction details. Parameterized high-fidelity three-dimensional nonlinear analytical models are developed for the portfolios of bridge classes within different design eras. These models incorporate a wide range of geometric and material uncertainties, and their responses are characterized under seismic loadings. Fragility curves were then developed considering the vulnerability of multiple components and thereby help to quantify the performance of highway bridge networks and to study the impact of seismic design principles on the performance within a bridge class. This not only leads to the development of fragility relations that are unique and better suited for bridges in California, but also leads to the creation of better bridge classes and sub-bins that have more consistent performance characteristics than those currently provided by the National Bridge Inventory. Another important feature of this research is associated with the development of damage state definitions and grouping of bridge components in a way that they have similar consequences in terms of repair and traffic implications following a seismic event. These definitions are in alignment with the California Department of Transportation's design and operational experience, thereby enabling better performance assessment, emergency response, and management in the aftermath of a seismic event. The fragility curves developed as a part of this research will be employed in ShakeCast, a web-based post-earthquake situational awareness application that automatically retrieves earthquake shaking data and generates potential damage assessment notifications for emergency managers and responders.

Download or read book Performance based Decision making in Post earthquake Highway Bridge Repair written by Eugene Gordin and published by . This book was released on 2010 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: Post-earthquake highway bridge repair is an ever-present part of the lifecycle of transportation systems in seismic regions. These repairs require multi-level decisions involving various stakeholders with differing values. The improvement of the repair decision process, repair decision itself, and repair decision outcomes, requires an evaluation of current practices in post-earthquake repair decision-making. This dissertation assesses these current practices within the California Department of Transportation (Caltrans), outlines areas where the current process is ineffective, and highlights areas for improvement. Current repair decision-making practice is focused on the repair of individual bridges given a limited set of established repair methods. To improve upon these practices, this dissertation presents the Bridge Repair Decision Framework (BRDF), a new and unique methodology that allows for simultaneous consideration of all earthquake-damaged bridges as individual elements of a larger regional transportation system. This systematic approach enables the achievement of short- and long-term transportation system performance objectives while accounting for engineering, construction, financing, and public policy constraints. Furthermore, the BRDF allows for continuous refinement of the decision-making process to incorporate engineering and construction innovations, changes in the financial and public policy environment and, most importantly, changes in transportation system performance goals. While existing methodologies allow the incorporation of some of these changes, the BRDF provides a flexible structure that can account for all of these changes simultaneously. This is accomplished through a rigorous, performance-based, and risk-informed decision-making approach that presents repair decisions using a traditional engineering demand-capacity inequality. As a result, the BRDF empowers decision-makers with a holistic understanding of the transportation network condition on a microscopic (bridge) as well as macroscopic (overall system) level. The BRDF also accounts for the probabilistic nature of the earthquake hazard, bridge seismic capacity, and subsequent repair decisions, providing decision-makers with transparency regarding the uncertainties of system condition, repair method reliability, construction workforce availability, and public and business risks. BRDF decision-outcomes are technology-neutral as a result, greatly expanding the range of repair method alternatives that a decision-maker may consider while allowing for tradeoffs to be made between performance, cost, and time in light of transportation system condition and constraints. The BRDF is validated using a simulated bridge system case study that requires post-earthquake repair. This study was designed to demonstrate the functionality of the framework and to examine two alternate decision-making strategies: one with complete and the other with incomplete post-earthquake bridge damage state information. This case study led to refinements in the framework and insights about the benefits of additional information on the damage state of bridges in terms of overall repair time and cost of the regional transportation system. Additionally, the validation revealed areas where the current BRDF can be improved in future studies. The BRDF was created for large public transportation organizations such as the California Department of Transportation (Caltrans), where implementation of the BRDF requires several important prerequisites, including new database creation and additional training for engineers. Once implemented however, the BRDF allows decision-makers to potentially reduce repair costs and times, minimize system downtime, make better investments, and account for transportation system performance goals given current financial and public policy constraints.

Download or read book Seismic Response and Performance Based Assessment of Multi Span Bridge Ground Systems written by Abdullah S E S E Almutairi and published by . This book was released on 2019 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: The conducted study is directed towards enhancements in performance assessment of highway bridges under a wide range of earthquake input shaking scenarios. Seismic response of the superstructure is highly influenced by the global bridge-ground characteristics as an integral system. Therefore, nonlinear representation of the bridge deck, columns, abutments, and foundation response are to be integrated within a unified framework. On this basis, a performance-based earthquake engineering (PBEE) framework was extended and utilized to estimate the post-earthquake loss. To facilitate systematic execution of this analysis framework, a graphical user-interface was further developed and employed. For calibration purposes, a Finite Element (FE) model of an existing large heavily instrumented bridge system at Eureka, California (Samoa Channel Bridge) was developed. Calibration was undertaken based on the recorded earthquake response. Numerical simulations of the bridge model under seismic loading conditions were conducted. Simulation results show that the recorded data provide valuable insights to understand the seismic bridge response and to reliably estimate the damage. Using a practice-oriented pushover procedure, the response of a bridge subjected to liquefaction-induced lateral spreading was investigated. The analysis framework and representative results are presented, where the abutment lateral slope displacement is resisted by the entire bridge configuration. Permanent ground deformation induces longitudinal displacement on the abutment and consequently the entire bridge system. As such, the response of the bridge and its pile foundations were investigated and correlated with the imposed lateral spreading displacement. Overall, the novel contributions and findings are summarized as follows: (1) A bridge-ground seismic response computational analysis tool was further developed for routine practical applications; (2) In this tool, a PBEE framework was extended to handle multi-span bridge-ground systems within an integrated simulation environment; (3) Calibrated by recorded earthquake response, a framework was implemented for a representative large instrumented bridge-ground system in California to illustrate the involved response mechanisms and PBEE outcomes; (4) For response under lateral spreading considerations, a global bridge-ground systematic analysis framework was proposed and developed; (5) Patterned after an existing bridge in California, the framework was implemented with parametric studies addressing the procedure assumptions and potential retrofit bridge configurations.
