An Experimental Study of Elastomeric Bridge Bearings with Design Recommendations


Book Description

The purpose of this study was to analyze elastomeric bearing performance on the basis of elastomer hardness, shape factor, reinforcing shim orientation, degree of taper and compressive stress level with the goal of developing a simple design procedure which standardizes as many of those parameters as possible. Particular emphasis was placed on comparing the behavior of flat and tapered bearings. Experimentation included shear, compressive, and rotational stiffness tests, shear and compression fatigue loading, long-term compressive loading, and tests to determine compressive stress limits.

Mechanics of Rubber Bearings for Seismic and Vibration Isolation


Book Description

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 This comprehensive book: includes state of the art, as yet unpublished research along with all required fundamental concepts; is authored by world-leading experts with over 40 years of combined experience on seismic isolation and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.

Eco-design of Buildings and Infrastructure


Book Description

The Chair on Ecodesign for buildings and infrastructures was created by ParisTech in partnership with VINCI with the aim of developing evaluation and simulation tools that integrate all ecodesign aspects (e.g. greenhouse gas emissions, impact on biodiversity, depletion of resources, etc.) and provide genuine decision-aid instruments, based on a scientific approach, to all those involved in the urban environment (i.e. designers, builders and users). The present book takes stock of five years of research under the Chair. It starts by presenting some methodological bases of ecodesign, life cycle assessments, impact studies, and methods for planning and transport. Several specific subjects are then covered, i.e. public transport, parking, road traffic, the environmental profile of building materials, building retrofits, energy management, and biodiversity. The last part of the book sets out how the knowledge and tools developed under the Chair were applied to a case study: Cité Descartes in Marne la Vallée (Ile de France). This work is aimed at urban planners, local authorities, contracting clients, architects, engineering firms, contractors, building managers, research lecturers, and anyone interested in the environmental quality of the places we live in.
