One Question on FLUOROGOLD® Slide Bearings

04/16/2010 2:44 AM
WHY FLUOROGOLD®SLIDE BEARINGS?

Function

1.To accommodate movement under load with minimal friction.

2.To provide release or sliding surfaces at bearing ends of structural members, thereby accommodating shrinkage or thermal motion of members.

3.To isolate components or parts of a structure or assembly of parts when their relative movements must be independent of each other.

4.To provide a release bearing system in order to prevent stressesfrom entering certain parts of astructure.

How to intrepret release bearing system here?


5.To provide positive seismic separations.

Does positive mean proactive here?

This is evidently a proprietary product, so there may be some screwy sales lingo involved. (Which may be made worse if they are trying to mirror this or that bureaucratic gobbledygook.)

It may be desirable to allow adjacent structures to move relative to each other, for instance to avoid transmitting seismic deflections from one building section to another. In this respect, a sliding bearing could release one structure/zone/building from being shoved around by an adjacent item. This can be done by such techniques as swivel pipe joints, expansion loops, and the like. The relative movements can be accommodated by roller-type pipe hangers, slider pads, etc.

The phrase "seismic separation" seems sufficient on its own. The word "positive" doesn't add much, but "effective" might make a bit of sense. "Proactive" is a marketing-hype bullshit-bingo word.

I sympathize fully with your efforts to try to explain strange stuff in one language into yet another language, perhaps equally strange....

All 5 statements say the same thing. They are redundant.

The function of the bearing is: To accommodate movement under load with minimal friction. The rest say the same thing.

release bearing system allows free movement between two elements of the system.

I believe that you could remove the word "release" from the statement and just say bearing system and convey the same meaning.

Instead of: To provide positive seismic separations.

I'd say: To provide positive seismic isolation.

Tornado is right. This is marketing hype. You have a low friction bearing system that provides maximum seismic isolation.

Good luck.

Thanks you two on this. Actually i am considering to drop "relase" coz as you have said, it is a weak word.

I've used this system many times from bridge abutments to flue gas duct supports.

I think that "release bearing system" refers to situations where part of a structure is sacrificed to prevent damage to the main structure, akin to blast walls etc.

I think that "positive" simply means that there is no weak link to break as in some tie down systems.

Some of this funny terminology originates with the engineering specs attached to requests for proposals, they demand that the vendor include their terminology in thwe proposal.
