I’m attaching a .ssp file. It’s actually a simple thing: it’s a built-up steel beam that rests on two pins, one at each end, and is simply-supported with a 14,000 lbs load (for argument’s sake) in the middle of the supports, created using a spot. How should I model the supports? When I make the bearings for the pins both flexible, it gives an error. I have tried using the edges close by as fixed edges, and it works okay, but it’s not what I want. On top of that, the displacement values are about 50% of what they should be.
Any help would be appreciated.
