Hi, I have a question of using FOR in Opensees. I model a frame and want to add a brace to that and analysis it in each step.
Below there are two options that have to same results, but they have not (one of them element was added before For, other added in the loop). I would appreciate if you could help me. Thank You.
OPTION _ 1:
set ABrace 5.e-3
set MatBrace 1
uniaxialMaterial Elastic $MatBrace $E
for {set i 1} {$i<6564} {incr i} {
element truss 4 1 4 $ABrace $MatBrace
analyze 1 0.005
remove element 4
}

OPTION _ 2:
set ABrace 5.e-3
set MatBrace 1
uniaxialMaterial Elastic $MatBrace $E
element truss 4 1 4 $ABrace $MatBrace
for {set i 1} {$i<6564} {incr i} {
analyze 1 0.005
}
.
