HI EVERYONE,

Actually i model prestressed concrete beam in ANSYS APDL V19. As i know that it's not possible to apply with GUI as that of old version ANSYS V12. So i given a "inistate" command like this to apply prestrain to link 180,

inistate,set,dtyp,epel

inistate,set,mat,3 (as mat 3 = properties of prestress strand)

inistate,defi,,,,,,,,,,,,0.001903, is this command is correct.

i given this command once i completed the concrete and steel modelling and then given boundary condition and then i apply theses command to apply prestrain to link 180, as prestress itself is the first load step in ANSYS without any external load.

I consider it as load step 1, after this when i run the model and check the camber due to prestress it wont shows any value in the contour diagram even not deflected upward.

once i applied the commands directly without selecting the prestress steel and then again tried by selecting the prestress steel, in both case it wont considered the prestrain value at all.

Does i need to do few more steps, if yes please mention.

can anyone please kindly suggest a clear procedure (stepwise) for applying prestrain to link 180.

Thank you,

Regards,

Pandimani.
