Advances in Earthquake Engineering for Urban Risk Reduction
Author: S. Tanvir Wasti
Publisher: Springer Science & Business Media
ISBN: 1402045719
Category : Science
Languages : en
Pages : 563
Book Description
Earthquakes affecting urban areas can lead to catastrophic situations and hazard mitigation requires preparatory measures at all levels. Structural assessment is the diagnosis of the seismic health of buildings. Assessment is the prelude to decisions about rehabilitation or even demolition. The scale of the problem in dense urban settings brings about a need for macro seismic appraisal procedures because large numbers of existing buildings do not conform to the increased requirements of new earthquake codes and specifications or have other deficiencies. It is the vulnerable buildings - liable to cause damage and loss of life - that need immediate attention and urgent appraisal in order to decide if structural rehabilitation and upgrading are feasible. Current economic, efficient and occupant-friendly rehabilitation techniques vary widely and include the application either of precast concrete panels or layers, strips and patches of fiber reinforced polymers (FRP) in strategic locations. The papers in this book, many by renowned authorities in earthquake engineering, chart new and vital directions of research and application in the assessment and rehabilitation of buildings in seismic regions. While several papers discuss the probabilistic prediction and quantification of structural damage, others present approaches related with the in-situ and occupant friendly upgrading of buildings and propose both economical and practical techniques to address the problem.

Next Generation of Bridge Columns for Accelerated Bridge Construction in High Seismic Zones
Author: Mostafa Tazarv
Publisher:
ISBN:
Category : Columns, Concrete
Languages : en
Pages : 406
Book Description
Longitudinal bar debonding allowed spread of yielding and prevented premature failure of reinforcements in UHPC-filled duct connections and grouted coupler column pedestal. The SMA-reinforced ECC column showed superior seismic performance compared to a conventional column in which the plastic hinge damage was limited to only ECC cover spalling even under 12% drift ratio cycles. The column residual displacements were 79% lower than CIP residual displacements on average due to the superelastic NiTi SMA longitudinal reinforcement, and higher base shear capacity and higher displacement capacity were observed. The analytical modeling methods were simple and sufficiently accurate for general design and analyses of precast components proposed in the present study. The proposed symmetrical material model for reinforcing NiTi superelastic SMA was found to be a viable alternative to the more complex asymmetrical model.

Seismic Assessment and Retrofit of Reinforced Concrete Columns
Author: Konstantinos G. Megalooikonomou
Publisher: Cambridge Scholars Publishing
ISBN: 9781527527850
Category : Columns, Concrete
Languages : en
Pages : 387
Book Description
Reinforced concrete columns play a very important role in structural performance. As such, it is essential to apply a suitable analytical tool to estimate their structural behaviour considering all failure mechanisms such as axial, shear, and flexural failures. This book highlights the development of a fiber beam-column element accounting for shear effects and the effect of tension stiffening through reinforcement-to-concrete bond, along with the employment of suitable constitutive material laws.

Book Description
This is the twenty-ninth volume in the Earthquake Engineering Research Institute's series, Connections: The EERI Oral History Series. EERI began this series to preserve the recollections of some of those who have had pioneering careers in the field of earthquake engineering. Significant, even revolutionary, changes have occurred in earthquake engineering since individuals first began thinking in modern, scientific ways about how to protect construction and society from earthquakes. The Connections series helps document this important history. This volume in the EERI Oral History Series presents the life and career of Anil K. Chopra, Professor Emeritus in the Department of Civil and Environmental Engineering at the University of California, Berkeley. After he graduated from college in India, he went to UC Berkeley to earn his Master's and PhD degrees, then taught at the University of Minnesota before returning to join the faculty of UC Berkeley for the next 47 years, retiring in 2016. The first class he was asked to teach at UC Berkeley was structural dynamics, a course which had been started by his mentors, Ray Clough and Joe Penzien. His work in that field resulted in a number of publications on a wide range of topics in earthquake engineering and structural dynamics. Chopra chaired the structural analysis committee of the project producing the influential ATC-3, Tentative Provisions for the Development of Seismic Regulations for Buildings, and he tells interesting stories about working with Nate Newmark, Emilio Rosenblueth, Henry Degenkolb, and others. His expertise in structural dynamics resulted in his being asked to write the EERI monograph on structural dynamics, Dynamics of Structures: A Primer, and later led to his very widely used university textbook, Dynamics of Structures: Theory and Application to Earthquake Engineering, now in its fifth edition. A major theme in Chopra's research is the seismic analysis and design of concrete dams. He and a number of PhD students developed procedures for earthquake analysis of concrete dams, and he has consulted on dozens of major projects around the world. In 2020 he published his comprehensive book on the subject, Earthquake Engineering for Concrete Dams: Analysis, Design, and Evaluation.

Seismic Design and Retrofit of Bridges

Category : Technology & Engineering

Pages : 704
Book Description
Because of their structural simplicity, bridges tend to beparticularly vulnerable to damage and even collapse when subjectedto earthquakes or other forms of seismic activity. Recentearthquakes, such as the ones in Kobe, Japan, and Oakland,California, have led to a heightened awareness of seismic risk andhave revolutionized bridge design and retrofit philosophies. In Seismic Design and Retrofit of Bridges, three of the world's topauthorities on the subject have collaborated to produce the mostexhaustive reference on seismic bridge design currently available.Following a detailed examination of the seismic effects of actualearthquakes on local area bridges, the authors demonstrate designstrategies that will make these and similar structures optimallyresistant to the damaging effects of future seismicdisturbances. Relying heavily on worldwide research associated with recentquakes, Seismic Design and Retrofit of Bridges begins with anin-depth treatment of seismic design philosophy as it applies tobridges. The authors then describe the various geotechnicalconsiderations specific to bridge design, such as soil-structureinteraction and traveling wave effects. Subsequent chapters coverconceptual and actual design of various bridge superstructures, andmodeling and analysis of these structures. As the basis for their design strategies, the authors' focus is onthe widely accepted capacity design approach, in which particularlyvulnerable locations of potentially inelastic flexural deformationare identified and strengthened to accommodate a greater degree ofstress. The text illustrates how accurate application of thecapacity design philosophy to the design of new bridges results instructures that can be expected to survive most earthquakes withonly minor, repairable damage. Because the majority of today's bridges were built before thecapacity design approach was understood, the authors also devoteseveral chapters to the seismic assessment of existing bridges,with the aim of designing and implementing retrofit measures toprotect them against the damaging effects of future earthquakes.These retrofitting techniques, though not considered appropriate inthe design of new bridges, are given considerable emphasis, sincethey currently offer the best solution for the preservation ofthese vital and often historically valued thoroughfares. Practical and applications-oriented, Seismic Design and Retrofit ofBridges is enhanced with over 300 photos and line drawings toillustrate key concepts and detailed design procedures. As the onlytext currently available on the vital topic of seismic bridgedesign, it provides an indispensable reference for civil,structural, and geotechnical engineers, as well as students inrelated engineering courses. A state-of-the-art text on earthquake-proof design and retrofit ofbridges Seismic Design and Retrofit of Bridges fills the urgent need for acomprehensive and up-to-date text on seismic-ally resistant bridgedesign. The authors, all recognized leaders in the field,systematically cover all aspects of bridge design related toseismic resistance for both new and existing bridges. * A complete overview of current design philosophy for bridges,with related seismic and geotechnical considerations * Coverage of conceptual design constraints and their relationshipto current design alternatives * Modeling and analysis of bridge structures * An exhaustive look at common building materials and theirresponse to seismic activity * A hands-on approach to the capacity design process * Use of isolation and dissipation devices in bridge design * Important coverage of seismic assessment and retrofit design ofexisting bridges
