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.
not sure where you're going with this analysis.
you're going to apply the reaction loads on the ends of the beam? how will it be restrained?
half symmetry, even quarter symmetry will add stability but i'm not sure how you're currently restraining it to know where you might be running into trouble.
Thanks guys, I have tried the spring aproach, results weren't too great.
Normally I would apply a fixed hinge at either end, along the top, and then load the bottom, or just use one with symmetry. In this case, I'm trying to work according to the DNV Offshore carrying codes. It basically says that where the rope is located to the beam, there should be a stiffness of 10 N/mm in the vertical & horizontal directions.
Just not too sure how to include that in my setup.
i think you broke your problem down too quickly
here's how i think about it
you have a beam
its being held at some point by 2 cables
the most common thing that people do at this point is look at how the beam bends under its own load
is that what you are trying to do?
or is the beam connected somewhere to a ground and you want to pull up on it?
