Hi,<\/p>\n

I’m building a cable stayed bridge in ANSYS mechanical and struggling to get LINK180 to act in tension only.<\/p>\n

I’ve used SECCONTROL,,1 after defining the link element with SECTYPE but based on my output it doesn’t seem to have worked.<\/p>\n

<\/p>\n

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.<\/p>\n

For more context this is my definition of the link section:<\/p>\n

SECTYPE,4,LINK,,Cable
SECDATA,0.12566370614359174
SECCONTROL,,1<\/p>\n

Any help would be appreciated thanks.<\/p>\n","protected":false},"template":"","class_list":["post-326751","topic","type-topic","status-closed","hentry","topic-tag-1Dtensiononlyelement-1","topic-tag-bridge","topic-tag-cable","topic-tag-link180"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
