Optimum design of lead-rubber bearing system with uncertainty parameters

Structural Engineering and Mechanics, 2015
In this study, a non-stationary random earthquake Clough-Penzien model is used to describe earthquake ground motion. Using stochastic direct integration in combination with an equivalent linear method, a solution is established to describe the non-stationary response of lead-rubber bearing (LRB) system to a stochastic earthquake.

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

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
