Um die Auswirkungen von Erdbeben auf Gebäude, Brücken und andere empfindliche Konstruktionen zu mildern, wurden im Laufe der Jahre zahlreiche Technologien entwickelt. Eine der neueren hiervon ist die seismische Isolation: Sie beinhaltet den Einbau von Mechanismen, die das Gebäude von den Bewegungen des Untergrunds entkoppeln. Der Erfolg dieser Technik übertrifft den aller vorher bekannten Verfahren - ein Grund für Ingenieure und Architekten, sich genauer zu informieren. Dazu sei dieses Buch empfohlen. (04/99)

This book features chapters based on selected presentations from the International Congress on Advanced Earthquake Resistance of Structures, AERS2016, held in Samsun, Turkey, from 24 to 28 October 2016. It covers the latest advances in three widely popular research areas in Earthquake Engineering: Performance-Based Seismic Design, Seismic Isolation Systems, and Structural Health Monitoring. The book shows the vulnerability of high-rise and seismically isolated buildings to long periods of strong ground motions, and proposes new passive and semi-active structural seismic isolation systems to protect against such effects. These systems are validated through real-time hybrid tests on shaking tables. Structural health monitoring systems provide rapid assessment of structural safety after an earthquake and allow preventive measures to be taken, such as shutting down the elevators and gas lines, before damage occurs. Using the vibration data from instrumented tall buildings, the book demonstrates that large, distant earthquakes and surface waves, which are not accounted for in most attenuation equations, can cause long-duration shaking and damage in tall buildings. The overview of the current performance-based design methodologies includes discussions on the design of tall buildings and the reasons common prescriptive code provisions are not sufficient to address the requirements of tall-building design. In addition, the book explains the modelling and acceptance criteria associated with various performance-based design guidelines, and discusses issues such as selection and scaling of ground motion records, soil-foundation-structure interaction, and seismic instrumentation and peer review needs. The book is of interest to a wide range of professionals in earthquake engineering, including designers, researchers, and graduate students.

Ground motion due to earthquake excitation often induces disastrous disturbances that severely damage structures and their contents. Conventional earthquake-resistant design focuses on the strengthening of structures to avoid collapse, while little attention is paid to the prevention of damage as it is almost impossible to construct completely earthquake proof structures at reasonable cost. This state-of-the-art volume explores seismic isolation as an alternative and performance-based design approach to minimise earthquake induced loads and resulting damage in low to medium-rise buildings. A discussion of the characteristics, advantages and limitations of seismic isolation is followed by a demonstration of its capability to decouple a structure from the damaging effects of ground acceleration. Describes currently used seismic isolation systems in detail. Evaluates the performance of seismically isolated structures and provides examples of their response under earthquake action. Proposes a preliminary design methodology for seismically isolated structures. Accessible to both students and practising structural engineers who need to familiarise themselves with this approach.

"This primer describes the current state of seismic isolation technology and highlights issues and concerns which are unique to the design of isolated structures. Readers will rapidly gain practical knowledge related to base isolation design from this concise book. Included are the fundamentals of seismic isolation, design of isolated structures, analysis, and testing. Provided are overviews of of the topic that are accessible not only to structural engineers who have not been formally trained in base isolation design, but also to architects and students in a first-level engineering course. This book emphasizes practical issues, rather than theoretical issues, making it complementary to textbooks on earthquake engineering."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

My involvement in the use of natural rubber as a method for the protec 1976. At that time, tion of buildings against earthquake attack began in I was working on the development of energy-dissipating devices for the same purpose and had developed and tested a device that was even tually used in a stepping-bridge structure, this being a form of partial isolation. It became clear to me that in order to use these energy devices for the earthquake protection of buildings, it would be best to combine them with an isolation system which would give them the large displace ments needed to develop sufficient hysteresis. At this appropriate point in time, I was approached by Dr. C. J. Derham, then of the Malaysian Rubber Producers' Research Association (MRPRA), who asked if I was interested in looking at the possibility of conducting shaking table tests at the Earthquake Simulator Laboratory to see to what extent natural rubber bearings could be used to protect buildings from earthquakes. Very soon after this meeting, we were able to do such a test using a 20-ton model and hand-made isolators. The eady tests were very promising. Accordingly, a further set of tests was done with a more realistic five storey model weighing 40 tons with bearings that were commercially made. In both of the test series, the isolators were used both alone and with a number of different types of energy-dissipating devices to en hance damping.

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.
