The Study of the Design parameter of Lead Rubber Bearing
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.This paper explains in a systematic way the formula and reasonable value range of the design parameter.These parameters include the diameter and height of lead pin,effective design deflection,the equivalent linear model,shear strain of rubber beating shear stress of the lead,initial rigidity and second rigidity and so on.At last this paper induces computing method of equivalent rigidity and equivalent damping constant and gives some examples o This paper gives scientific basis for the concrete design and makes the beating standard and serial to lay a foundation for its application.
