2dof pushover load scale

[toy0410]

Hello,
I have a problem about doing 2dof system push-over analysis.
Is it passable changing the pushover load scale when doing analysis?
For example, in the beginning load scale for 1st dof is 1; 2nd dof is 2.7 (1st at below, 2nd at top).
Then change load scales to 1:0.022 (1st:2nd) when 2nd shear force achieve some value i want.

yes .. you could a) put the loads in 2 different load patterns with different time series or b) add the required load pattern at each step and remove at end of step.

Dear fmk,
Thanks your reply. I follow your suggestion to put loads in 2 different load patterns, but the analysis fail to do load pattern 2. The code is follows. How could i correct the failure?
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------
pattern Plain 1 "Linear" {
load 101 1.0 0.0 0.0
load 1015 2.39 0.0 0.0
}
integrator DisplacementControl 1015 1 1
analyze 100
remove loadPattern 2
puts "First push done"

pattern Plain 2 "Linear" {
load 101 1.0 0.0 0.0
load 1015 1.77 0.0 0.0
}
integrator DisplacementControl 1015 1 0.1
analyze 300
puts "pushover analysis done..."
