High Elevation Walkway Connections
High Elevation Walkway Connections
(OP)
I am working on a high elevation platform/walkway connecting two vessels. I am looking for examples, input, or advise on the best connections for the job.
For different elevation platforms I've seen stairs hinged at the top, then free at the bottom to allow for twist, sway, etc. however, the client wants some walkways at the same elevation.
I know slotted connections and over sized bolt holes can allow for movement, but for this project we are up 200 feet in the air, with some pretty good sway and deflection (and I have read about the failures with slotted connections).
I was also advised to rest the walkway beam on another member and leave a gap equal to the addition of the lateral movement in each vessel (and if over 1", provide a plate on top) and the metal on metal will allow movement. But what about vertical movement? Twisting? I need a connection that will allow and withstand all of it.
Thanks for any input!

Are you suggesting the other end be free to allow for twist and lifting? Guided slide bearings only allow for movement in one direction, correct?
