Girder Truss Supports
Girder Truss Supports
(OP)
I am involve in a project where we need to design a 80 feet clear span girder truss that will have wide flange members. The girder will support a three storey wood frame for dwelling. We are going to restrain the girder with pin on one end and roller on the other. My question is the roller support, should a slotted bolt connection (to allow translation in horizontal axis) at bearing point considered as roller? s there any problem with this connection?

Expense.
You can't really match the analytical case. There's friction, corrosion, misalignments, etc.
It only changes the analysis slightly and in a conservative way.
You need the fixity to support the top of the walls.
This is done on bridges, but they're outdoor structures, with more temperature effects.

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