rotated supports

rotated supports

(OP)
Hi,

maybe just simple question, but now i solve simultaneously some another partial problems, and currently i am not able to solve this one.

i model a cable by link10 going under a angle according to attached picture. I do not care about upper support, but in lower suppor i want to apply a force in direction of the cable.

i tried to deffine a local CS and hoped, that when i apply support it will by in correct direction, but this did not work.

Any input is highly appreciated becouse of deadline and lack of time.

update

i tried to model the cables horizontaly (this does not solve my previous problem - finally cable will be a part of a bridge) and apply the force in direction of cable, but i want to model slack of cable from self-weight as well - so i decomposed gravity acceleration to x and z direction, but after non-lin solution i can see only symmertic deformation in z-direction. ...?

RE: rotated supports

I don't know what you are on about in the second question but for the first you have to rotate the nodes into the local cordinate system ie.

csys,11
nsel,s,,,2
nrotat,all
f,fy,2,100
alls
etc...
