Steel Structure on Bearing Pad

[ingdaniel]

Hi all,

I have a structure and I want a couple of the supports have bearing pad (rubber), to give some movement and reduce the longitudinal load. The vertical load is low (least the 10 tonf).

What material can I use? neoprene will work?

There is any catalog for select the thickness of the pad?

There ir any way or table to estimate the horizontal and vertical stiffness of the support?

First time I do this....

Thanks in advance,

Best regards...

I'd start by looking at the bearing pad info in the PCI manual. This kind of thing is done all the time in precast and the principles are the same. You can also google Masticord and Fabreeka. They are two common suppliers and they each offer good design guides.

The greatest trick that bond stress ever pulled was convincing the world it didn't exist.

Here are a couple of spreadsheets that might get you started. It would be important to learn about pad design first, though, to understand the principles.
