Hi Everyone,

If I have a beam that is loaded at either end with half its carrying load (P), but also lifted by cables at either end, how would I analyze this scenario?

The payload is easy, its just P/2 at either end, but how would I define the restraints of the cables lifting it, in such a way that it would not compromise any of the beams behaviour? Since the cables are at an angle, there would also be a compressive horizontal component and not only the vertical load.

I have included a simple illustration below.

I have tried a number of options, including Remote Loads, exceptionally stiff Springs, Links & Rigid Connections. None of them allow for the suitable behaviour. The only one that comes close is the link, but it makes the model very unstable.

I'd apply symmetry and model the cable with a spring element. You have two planes of symmetry that you can take advantage of, so remember to apply 1/4 of the total load.
