Effects of different Actions at the end of contruction stage analysis

Hi,
I am currently running a bridge model and I have implemented the construction stage analysis using CSM. After running it, I get a single load case 4XXX with the effects of all loads applied during construction.

I would like to access the effect of each action independently. For example, I would like to separate the effects of self-weight (G_1), cable stressing(P_4) and superimposed dead load (G_2 and G_3) at the end of construction.

Is there a way I can do this?

Thank you.

You can use maxima after csm analysis with single action.

Apologies, your response is not clear to me. When I call maxima after the CSM analysis the only results I get are the total (G1+G2+P). Can you clarify how to separate the results? Thank you

there is an example:

+prog maxima
head acts solo

comb 101 expl 10100 none
  add G_1 facu 1 1
supp 101 mami auto

comb 102 expl 10200 none
  add G_2 facu 1 1
supp 102 mami auto

comb 103 expl 10300 none
  add G_3 facu 1 1
supp 103 mami auto

comb 104 expl 10400 none
  add P_4 facu 1 1
supp 104 mami auto
end

There is a single action facu=1 facf=1 in each combination only, so supp ... auto may be too excessive.

Thank you for your reply. I had tried to run maxima as described but the results I get are not at the end of construction but rather at the stage where the loads are introduced. (e.g. I have reactions at the temporary supports)

The code above adds all stages defined as G_X.
