long module with expansion joint during shipping

[westheimer1234]

anyone had a case where the module has expansion joint during shipping? how did you resolve this?

this question was asked to me during my interview with an oil and gas EPC company.. i never had a case like this coz we split our modules at the expansion joint..

how does one design an expansion joint connection of a steel in a high seismic location?

say you have a shear plate with slotted holes and 2 nuts finger tightened..

thanks,

I didn't understand "module" in the first post, I thought you might be talking about ductwork with bellows expansion joints.

At the risk of sounding as though I'm being patronizing, you have to design for the forces that will be met. Usually, a sliding connection is a guide, it limits movement in one direction and permits it in another. That module will usually have an anchor, or sometimes, a two way guide in that it allows rotation, at the other end.

You may have to replace a slide plate with a pair of tees on either side of a wide flange stub in the event of large lateral seismic loads

On the transport thing, I agree, I wouldn't do it, but if I had to, I would use some torqued up friction bolts for shipping.

Timing has a lot to do with the outcome of a rain dance.

pad, what's a typical expansion joint detail again for steel structure in high seismic area and why it should be like that?

thanks,

westheimer1234, I'm not much help there, I have had to resist some heavy forces, but not because of high seismic loads. I was hoping someone else would cover that.
