Hi,

I'm building a cable stayed bridge in ANSYS mechanical and struggling to get LINK180 to act in tension only.

I've used SECCONTROL,,1 after defining the link element with SECTYPE but based on my output it doesn't seem to have worked.

When I plot FXI and FXJ the longest link element still seems to be taking a compressive load as its colour is within the -1966 to -9485 kN range. Am I using SECCONTROL incorrectly or is there some issue with my plot? All I did was make an etable with FXI and FXJ and then plot it with PLLS. The compressed cables are definitely the correct section since I can select them with the section ID.

For more context this is my definition of the link section:

SECTYPE,4,LINK,,Cable
SECDATA,0.12566370614359174
SECCONTROL,,1

Any help would be appreciated thanks.

Hi Dan,

It looks like you have a duplicate post for the same query, so I will close this post and keep the other one open.
