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.

This book was released on 2020 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of this research was to quantify the material strain limits for seismic assessment of existing sub-standard reinforced concrete bridge bents considering operational performance design criteria. Limited confidence exists in the current material strain limit state for operational performance criteria due to lack of experimental results considering the typical detailing of Oregon bridges and the cumulative damage effect resulting from an anticipated long-duration Cascadia Subduction Zone (CSZ) event. Component details for bridge bents such as geometry and reinforcing details were determined through a statistical analysis of available bridge drawings built prior to 1990 in the State of Oregon. Three full-scale bridge bent column-footing subassembly specimens were constructed and subjected to reverse cyclic lateral deformations utilizing a traditional loading protocol and a protocol representing the demands expected from a CSZ earthquake. The tests were designed so that variable axial loading could be applied in order to simulate the secondary effects experienced in a column that is part of a multi-column bent during an earthquake event. Material strains along with global and local deformation quantities were measured with a suite of external and internal sensors mounted to and embedded in the specimens. Despite having sub-standard seismic detailing, all three specimens exhibited ductile behavior under reverse cyclic lateral loading, achieving a minimum displacement ductility of 8.0. The obtained results also suggest that the material strain limits currently used for the seismic evaluation of existing bridges in Oregon considering operational performance criteria are conservative, but may still require further experimental validation. Finally, strain limits based on previous research at Portland State University (PSU) were compiled and combined with the results from this study to propose recommended strain limit values.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of this research was to evaluate the seismic performance of existing sub-standard reinforced concrete (RC) bridge column-spread footing subassemblies and to quantify the material strain limits through a full-scale experimental program. A total of six column-footing test specimens with pre-1990 construction details were subjected to reverse cyclic lateral loading, utilizing a conventional three-cycle symmetric loading protocol and a protocol representing the demands expected from a CSZ earthquake. Additionally, the tests were designed so that variable axial loading could be applied to simulate the secondary load effects experienced during an earthquake in a column that is part of a multi-column bent. A rapid repair method incorporating semi-permanent installation was also developed, anticipating the need for quick measures following the Cascadia Subduction Zone (CSZ) earthquake, which is expected to damage the existing bridges in the Pacific Northwest and spread geographically throughout the region. The proposed repair methodology uses capacity design principles to protect the remainder of the bridge from future earthquakes and eradicates the need for establishing rebar continuity, resulting in a less labor-intensive repair method. The adopted concept is to utilize U-shaped metallic plates as externally attached ductile fuses to be anchored to the non-damaged part of the column, hence bypassing the damaged zone to restore the lateral capacity.
Book Synopsis Post-earthquake Evaluation and Emergency Repair of Damaged RC Bridge Columns Using CFRP Materials by : Ashkan Vosooghi

This book was released on 2010 with total page 742 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of the study was to develop a rapid and effective repair method using carbon fiber reinforced polymer (CFRP) materials for earthquake-damaged reinforced concrete bridge columns. This study consisted of three main phases. In the first phase, a data base of 33 test columns was developed and analyzed and five distinct apparent seismic damage states were defined. The damage states were correlated to measured seismic response parameters in terms of drift, frequency, strains, and yield and ultimate displacements. Fragility curves were developed and applied for two case studies in performance-based design (PBD) and performance-based assessment (PBA) of bridge columns. Comprehensive experimental and analytical studies were conducted in the second phase of the study. Two standard single columns, one standard two-column bent, and two substandard columns were tested on a shake table, repaired using CFRP fabrics, and retested on the shake table to evaluate the proposed repair procedure. The measured data were extensively analyzed to investigate the performance of the repaired columns compared to the original column responses. It was concluded that the strength and ductility of the standard columns were successfully restored and those of sub-standard columns were upgraded to the current seismic standards after the repair. However, the stiffness was not restored due to material degradation during the original column tests. Even though the repair process was done rapidly and was treated as "emergency" repair with implication that it was a temporary measure, it can be treated as a permanent repair as long as the stiffness of repaired columns is sufficient for non-seismic loading. In the analytical studies, extensive static and dynamic nonlinear analyses were performed on the column models and a simple analytical method was developed for the repaired columns to account for stiffness degradation. Based on the results from the experimental and analytical studies, repair design recommendations were developed in the third phase to aid bridge engineers in quickly designing the number of layers of CFRP layers based on the apparent damage and basic information about the column fixity, size, and reinforcement.

Download or read book Predicting Seismic Performance of Circular Reinforced Concrete Bridge Columns written by Hamid Anghaie and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "The 2014 Canadian Highway Bridge Design Code (CHBDC) has been significantly modified to improve the seismic design and analysis of new bridges. Performance-Based Design has been implemented in the code as the main seismic design methodology for bridges. The goal of this research is to provide appropriate damage indicators that can be used in the performance-based design approach. Numerical models were developed using the Response-2000 program and the OpenSees platform. Nonlinear pushover analyses were conducted on a number of columns tested by other researchers. The numerical models were validated by comparing the predictions to the test results and the accuracy of the predictions was investigated. These studies provide guidance for engineers in the numerical modeling of bridge columns and also provide damage indicators for cover spalling, residual crack width, longitudinal bar buckling, and longitudinal bar fracture.

Book Synopsis Displacement-based Seismic Design of Structures by : M. J. N. Priestley
Download or read book Displacement-based Seismic Design of Structures written by M. J. N. Priestley and published by Iuss Press. This book was released on 2007 with total page 750 pages. Available in PDF, EPUB and Kindle. Book excerpt: Displacement-Based Seismic Design of Structures is a book primarily directed towards practicing structural designers who are interested in applying performance-based concepts to seismic design. Since much of the material presented in the book has not been published elsewhere, it will also be of considerable interest to researchers, and to graduate and upper-level undergraduate students of earthquake engineering who wish to develop a deeper understanding of how design can be used to control seismic response. The design philosophy is based on determination of the optimum structural strength to achieve a given performance limit state, related to a defined level of damage, under a specified level of seismic intensity. Emphasis is also placed on how this strength is distributed through the structure. This takes two forms: methods of structural analysis and capacity design. It is shown that equilibrium considerations frequently lead to a more advantageous distribution of strength than that resulting from stiffness considerations. Capacity design considerations have been re-examined, and new and more realistic design approaches are presented to insure against undesirable modes of inelastic deformation. The book considers a wide range of structural types, including separate chapters on frame buildings, wall buildings, dual wall/frame buildings, masonry buildings, timber structures, bridges, structures with isolation or added damping devices, and wharves. These are preceded by introductory chapters discussing conceptual problems with current force-based design, seismic input for displacement-based design, fundamentals of direct displacement-based design, and analytical tools appropriate for displacement-based design. The final two chapters adapt the principles of displacement-based seismic design to assessment of existing structures, and present the previously developed design information in the form of a draft building code. The text is illustrated by copious worked design examples (39 in all), and analysis aids are provided in the form of a CD containing three computer programs covering moment-curvature analysis (Cumbia), linear-element-based inelastic time-history analysis (Ruaumoko), and a general fibre-element dynamic analysis program (SeismoStruct). The design procedure developed in this book is based on a secant-stiffness (rather than initial stiffness) representation of structural response, using a level of damping equivalent to the combined effects of elastic and hysteretic damping. The approach has been fully verified by extensive inelastic time history analyses, which are extensively reported in the text. The design method is extremely simple to apply, and very successful in providing dependable and predictable seismic response.
