multiple "integrator DisplacementControl" in one F

[GunAndRose]

Hey, all
I am trying to include the sectional analyses/pushover alalyses in one openSees run.

Because these analyses require "integrator DisplacementControl". So my question is whether it is possible to include multiple "integrator DisplacementControl" commands such that I can do multiple sectional analyses/pushover alalyses in one run of OpenSees to save time.

Thanks.

not really.
you can do it in series, or set up the elements in parallel...

Thanks, silvia.

I am not sure on your saying "set up the elements in parallel". Because of the integrator command, I was thinking that for each sectional analysis/pushover analysis on one section/structural member, we need a reference node for the analysis on each section/structural member.

Could you please be more specific?

Thanks.

you connect many elements that have different sections to the same nodes.
i do this to test a number of materials at the same time:

element truss [expr 1 + 100] 1 2 $AgCol [expr $IDmat + 100];
element truss [expr 1 + 200] 1 2 $AgCol [expr $IDmat + 200];
element truss [expr 1 + 300] 1 2 $AgCol [expr $IDmat + 300];
element truss [expr 1 + 400] 1 2 $AgCol [expr $IDmat + 400];

recorder Element -file $dataDir/Fele${endword}A.out -time -ele [expr 1 + 100] localForce
recorder Element -file $dataDir/Fele${endword}B.out -time -ele [expr 1 + 200] localForce
recorder Element -file $dataDir/Fele${endword}C.out -time -ele [expr 1 + 300] localForce
recorder Element -file $dataDir/Fele${endword}D.out -time -ele [expr 1 + 400] localForce
