Hi all,
I’m having some troubles using created LCs from MAXIMA COMB, SUP functions and using them in NONL analysis in ASE.
Maybe the approach is wrong…
COMB NO 4 EXTR DESI BASE 6000 TYPE RARE TITL “FAT_B”
ACT G_1
ACT G_2
ACT C_1 GAMU 1.35 1
ACT C_2 GAMU 1.35 1
SUPP COMB 3 EXTR MAX ETYP QUAD TITL “FAT”
SUPP COMB 4 EXTR MAX ETYP QUAD TITL “FAT_B”
end
+PROG ASE urs:49 $ Non-linear analysis ULS (Area elements)
HEAD Non-linear analysis ULS (Area elements)
PAGE UNII 0
SYST PROB NONL ITER 90 TOL 0.002 NMAT YES
NSTR KSV UL
REIQ LCR 11 FACT 1.0 LCRS 99 $ use reinforcement from design case 1, new reinforcement saving in design case 99
LC 6001
END
When I input LC number from MAXIMA in ASE there’s an error that there are no loads stored for this loadcase (for this example I tried 6001, 6003, 6005 etc. still the same)
However when I use loads created in sofiload it works fine.
I assume my LC definition approach is wrong.
MAXIMA is only of limited use for non-linear calculations: You can only use it to determine the relevant individual load case participations for selected elements and save the superposition internal forces.
For the calculation of a non-linear total load case, nothing can be done with the superimposed load cases (in the case of extreme loads, different individual load cases are thrown together element by element), as they do not contain any loads for calculation.
MAXIMA can, however, save fixed load case combinations according to the input requirement.
The old version (still) works with SUPP CSAV, the new version is TRAC CSAV.
SOFILOAD can then use LF…COMB to access this LF combination and convert it into an LF for calculating with ASE.
In the example MAXIMA1.DAT there is a TRAC record, which I have extended by CSAV, in the CDB you can then see how the storage for SOFILOAD takes place there.
