Download or read book Mechanics of Rubber Bearings for Seismic and Vibration Isolation written by James M. Kelly and published by John Wiley & Sons. This book was released on 2011-08-24 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Widely used in civil, mechanical and automotive engineering since the early 1980s, multilayer rubber bearings have been used as seismic isolation devices for buildings in highly seismic areas in many countries. Their appeal in these applications comes from their ability to provide a component with high stiffness in one direction with high flexibility in one or more orthogonal directions. This combination of vertical stiffness with horizontal flexibility, achieved by reinforcing the rubber by thin steel shims perpendicular to the vertical load, enables them to be used as seismic and vibration isolators for machinery, buildings and bridges. Mechanics of Rubber Bearings for Seismic and Vibration Isolation collates the most important information on the mechanics of multilayer rubber bearings. It explores a unique and comprehensive combination of relevant topics, covering all prerequisite fundamental theory and providing a number of closed-form solutions to various boundary value problems as well as a comprehensive historical overview on the use of isolation. Many of the results presented in the book are new and are essential for a proper understanding of the behavior of these bearings and for the design and analysis of vibration or seismic isolation systems. The advantages afforded by adopting these natural rubber systems is clearly explained to designers and users of this technology, bringing into focus the design and specification of bearings for buildings, bridges and industrial structures. This comprehensive book: includes state of the art, as yet unpublished research along with all required fundamental concepts; is authored by world-leading experts with over 40 years of combined experience on seismic isolation and the behavior of multilayer rubber bearings; is accompanied by a website at www.wiley.com/go/kelly The concise approach of Mechanics of Rubber Bearings for Seismic and Vibration Isolation forms an invaluable resource for graduate students and researchers/practitioners in structural and mechanical engineering departments, in particular those working in seismic and vibration isolation.

Download or read book The Coupled Horizontal vertical Response of Elastomeric and Lead rubber Seismic Isolation Bearings written by and published by . This book was released on 2006 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elastomeric and lead-rubber bearings are two types of seismic isolation hardware widely implemented in buildings, bridges and other infrastructure in the United States and around the world. These bearings consist of a number of elastomeric (rubber) layers bonded to intermediate steel (shim) plates. The total thickness of rubber controls the low horizontal stiffness and the close spacing of the intermediate shims provides a large vertical stiffness for a given bonded rubber area and elastomer shear modulus. Conceptually, a lead-rubber bearing differs from an elastomeric bearing only through the addition of a lead-core typically located in a central hole. During earthquake ground shaking, the low horizontal stiffness of elastomeric and lead-rubber bearings translates into large lateral displacements, typically on the order of 100--200% rubber shear strain, that might lead to significant reductions in the axial load carrying capacity and vertical stiffness of the individual bearings. This dissertation presents an analytical and experimental investigation of the coupled horizontal-vertical response of elastomeric and lead-rubber bearings focusing on the influence of lateral displacement on the vertical stiffness. Component testing was performed with reduced scale low-damping rubber (LDR) and lead-rubber (LR) bearings to determine the vertical stiffness at various lateral offsets. The numerical studies included finite element (FE) analysis of the reduced scale LDR bearing. The results of the experimental and FE investigations were used to evaluate three analytical formulations to predict the vertical stiffness at a given lateral displacement. From component testing the vertical stiffness of the LDR and LR bearings was shown to decrease with increasing lateral displacement and at a lateral displacement equivalent to 150% rubber shear strain a 40--50% reduction in vertical stiffness was observed. One of the three analytical formulations, based on the Koh-Kelly two-spring model, was shown to predicted the measured reduction in vertical stiffness of the LDR and LR bearings at each lateral offset with reasonable accuracy. In addition, earthquake simulation testing was performed to investigate the coupled horizontal-vertical response of a bridge model isolated with either LDR or LR bearings. The results of simulations performed with three components of excitation were used to evaluate an equivalent linear static (ELS) procedure for the estimation of the vertical load due to the vertical ground shaking. The equivalent linear static procedure was shown to conservatively estimate measured maximum vertical loads due to the vertical component of excitation for most simulations.

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 2012-04-17 with total page 233 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.

Download or read book Evaluation of Elastomeric Bearings for Seismic Design written by Cale Ash and published by . This book was released on 2002 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elastomeric bridge bearings have been used by various states in the mid-America region to accommodate thermal movement of bridge decks for over thirty years. Their potential role for mitigating damage in the infrequent but high consequence earthquakes that characterize the central United States is explored in this project. The potential protective role of conventional elastomeric bearings is critically influenced by material properties such as shear modulus, known to be temperature dependent. The degree of influence at low temperatures is determined through experimental studies. Slip characteristics of in-service aged and contaminated Teflon interfaces are determined. Full-scale bearings taken from existing bridges in addition to new bearings form the basis of these tests. Materials tests performed on the elastomer characterize the properties of aged bearings. The influence of these physical properties on possible bridge damage caused by earthquake ground shaking is assessed through computational simulations. A retrofit bearing with improved details for seismic isolation is designed and tested. An apparatus for testing the bearings was developed to simulate actual loading conditions. The apparatus provides a temperature-controlled chamber to allow for low temperature testing. Test protocols are developed to address the influence of testing parameters such as low temperature exposure and compressive stress. The prototype retrofit bearing design was also tested in this setup. The seismic response of a representative bridge is assessed by computational simulations conducted using the nonlinear analysis software DRAIN-2DX.
