Behaviour of lead-rubber bearings

Structural Engineering and Mechanics, 1998
Experimental work undertaken to investigate the behaviour of lead-rubber bearings under compression and a combination of compression and shear or rotation has been reported on elsewhere. However, it is difficult to determine the state of stress within the bearings in terms of the applied forces and the interaction between the lead plug and the steel ...

System identification of a bridge with lead–rubber bearings

Computers & Structures, 2000
Abstract This study develops an identification algorithm to investigate the dynamic properties of a base-isolated highway bridge equipped with lead–rubber bearings. A linear model is used for the substructure while a bilinear hysteretic model is chosen for the bearing system.

Design Method for Bridges on Lead‐Rubber Bearings

Journal of Structural Engineering, 1989
This paper presents a design method based on a parametric study by Turkington (1987) of the response of bridge superstructures supported on lead-rubber bearings and subjected to the 1940 El Centro (N-S component) and Parkfield earthquakes. The study showed trends of both period shift and additional damping brought about by the inelastic behavior of the

The Study of the Design Parameter of Lead Rubber Bearing

Applied Mechanics and Materials, 2012
The Lead-Rubber-Bearing is a type of isolation device in entirety. Its design parameter is complicated. when it is used in bridges, it always need plenty of time to design. It is not beneficial to its application and dissemination. The design formula now available are lack of relevance，can not provide a clear and distinct computation measure.

Seismic Design of Bridges on Lead‐Rubber Bearings

Journal of Structural Engineering, 1989
This paper reports on a parametric study of the response of bridge superstructures supported on lead‐rubber bearings when subjected to the 1940 El Centro earthquake (N‐S component) and the 1966 Parkfield earthquake. The effect of parameters such as lead‐plug size and aspect ratio, bearing thickness and yield strength, pier, abutment, and superstructure

Principles of scaling and similarity for testing of lead–rubber bearings

Earthquake Engineering & Structural Dynamics, 2010
AbstractLead–rubber bearings are seismic isolators that have been extensively used to protect buildings, bridges and mission‐critical infrastructure from the damaging effects of earthquake shaking. Testing of isolators, including lead–rubber bearings, is conducted either for research purposes (for example, shake table testing) or for determination of ...

Application of Lead Rubber Bearing in Curved Continuous Bridge

Advanced Materials Research, 2011
Based on the general FEA program, the bidirectional nonlinear behavior of lead rubber bearing is taken into account by using two orthogonal nonlinear spring elements. Considering the effect of radius of curvature, lead diameter and dissimilar seismic motions, dimensional FEA model of seismically isolated curved continuous bridge is established. And the

A mechanical tension-resistant device for lead rubber bearings

Engineering Structures, 2017
Abstract Tensile stresses in laminated rubber bearings can create expandable cavities and cause damage to spread inside the rubber, which may lead to inestimable impact on the mechanical performance of the isolators. Thus, laminated rubber isolation systems are mainly used in multistoried buildings in which compression state is maintained at the ...

Stability of Elastomeric and Lead-Rubber Seismic Isolation Bearings

Journal of Structural Engineering, 2012
Elastomeric and lead-rubber bearings are two commonly used types of seismic isolation devices. During seismic events, some of the bearings in an isolation system will be subjected to large axial compressive loads, caused by gravity plus overturning forces, accompanied by simultaneous large lateral displacements.

Development of a design procedure for bridges on lead-rubber bearings

Engineering Structures, 1989
Abstract This paper presents a design method that is based on a parametric study of the response of bridge superstructures supported on lead-rubber bearings and subjected to El Centro 1940 N/S component and the 1966 Parkfield earthquakes. The effect of parameters such as lead plug sizes and aspect ratio, bearing thickness and yield strength, pier ...
