Stresses to the Database

Dear all

Could someone explain me when data is written to the database.
I’m asking for the moments, normal forces and stresses in the beam:

+prog maxima urs:7
head superposition
echo opt no
comb no 1 extr desi type desi
act type g
lc 1
lc 2
supp comb 1 extr max etyp beam type MY lc 1001 $This is the loadcases that is read by sof_cdb_get
supp comb 1 extr max etyp beam type N lc 1001
supp comb 1 extr max etyp beam type SIG sele Y+,Y-,Z+,Z-


But when I go (after running the .dat file) to Database Tools>Database information, there is no key that contains stresses. What do you need to do for having data stored at the keys.

Kind regards

Stress are calculated in aqb
What you have done is enevelope of forces that causes extremal stresses bur without direct calculation of the

Prog aqb
Lc xxx
Stre k

Thank you, It worked!

Hello Sharon,

MAXIMA does not calculate and save stresses. The superpositions for SIG is done as follows:

  • internal temporary calculations of the normal stress of the initial load cases
  • superpositions for these normal stresses
  • printout and saving of the results as associated internal forces
