Multi-Support Excitation Pattern command

[Baodkt]

Hi,
I had the problem when I used Multi-support command, I don't know why recording acceleration values are so much different with input acceleration, but recording displacement values are the same as input motion.
Can anyone please help me to find out the reason

Here is my code which I use to apply input motion

for {set i 1} {$i<= 35} {incr i} {
timeSeries Path [expr $i+100] -dt 0.011712 -filePath input/acc_node$i.txt -factor 1
timeSeries Path [expr $i+200] -dt 0.011712 -filePath input/vel_node$i.txt -factor 1
timeSeries Path [expr $i+300] -dt 0.011712 -filePath input/disp_node$i.txt -factor 2

}

pattern MultipleSupport 101 {
for {set i 1} {$i<= 35} {incr i} {

groundMotion $i Plain -accel [expr $i+100] -vel [expr $i+200] -disp [expr $i+300]
imposedMotion [expr $i+400] 1 $i #node, dof, GM tag

}
}

thank you.

Which accelerations and displacements are you recording?

Dear selimgunay
I recorded from node 401 to 435, these nodes are applied inputmotion.

They should be the same. Are you sure you are checking the accelerations correctly? How about the velocities?

thanks for reply Seilimgunay
velocities are also different
here is my code
