Hi everyone...

I'm having a problem in modeling column elements, I want to use Member Type : Giberson 1-Component Yield Surface : Concrete Column(1) as in the manual for RUAUMOKO3D ITYPE=2 Reinforced Concrete BEAM-COLUMN (type 1) member. An example of the input data for the member type property is the following:

2 FRAME COL_002
2 0 0 0 4 1 0 0 0
1.3440E+05 5.1691E+04 6.4255E+03 4.2558E+06 2.1279E+06 2.1279E+06 6.4255E+03 6.4255E+03 .0 .0 .0
.0 35.0 .0 35.0 .0 .0 .0 .0
.00 .00 .02 .02
32.1 32.1 32.1 32.1
.0 .0 2.0 1.0 0
-1.4884E+06 -5.2453E+05 1.6750E+07 1.6750E+07 2.4563E+05
2.43 4.45 .10 .00 .00
.00 .30 1 2

And in the output file I get the next information:

I don't know what I'm missing in the interaction data, hope anyone can help me with this, I'll be very thankfull.

Thank you very much for the message. There is an error in the input for Concrete type 1 (only found with your hint) The Tension yield force is not copied if both ends of the member have the same yield actions. As as short term fix set end 2 to be different from end 1 and supply the same data. Concrete Yield 1, which is similar but more restrictive than the one in Perform 3D is somewhat limited in the shape of the yield surface formed which is why concrete surface 3 and 4 were developed and I have not used surface 1 since about 2002 which is why the error has not been detected. The subroutine does a check on input data and this data item fails the test.
