Hi there,

Does someone know how to deal with the situation in maxima program when you have several variable actions. I would like maxima to sum those two actions if unfovourable, unfortunatelly it chooses only the extreme value of those two.

+prog maxima urs:15.1
head variable actions
ECHO LOAD,FACT
COMB 1 EXPL TYPE DESI TITL 'variable actions'

ADD Q_1 Facu 1 facf 0
LC 5,6,7,8,9,10 type A1 fact 1.00
ADD Q_2 Facu 1 facf 0
LC (13 18 1) type A1 fact 1.00

SUPP 1 MAmi ETYP BEAM TYPE N,VY,VZ,MY,MZ LC 2001
SUPP 1 MAmi etyp NODE Type p,MX,MY,MZ LC 2201

END

How to write a formula that it sums results from Q_1 anad Q_2?

I would be grateful for your help.

Regards

Try this:
Code:
...
LC (13 18 1) type A2 fact 1.00  $ A2 instead of A1
...

Q_1 and Q_2 are part of one action. So all load cases of type A1 are used together. Using A2 you can change this behavior.
