EleLoad must be considered to mass?

[ishinabe]

Hello.

I have tried codes as follows.
--------------------------------------------------
[Definition of analytical model...]

puts "[eigen 1])]"
pattern Plain 1 1 {
eleLoad -ele 1 -type -beamUniform 1.0
}
loadControl 1.0 1
puts "[eigen 1])]"
--------------------------------------------------
The return value from first eigen command is different from that from second eigen command.
EleLoad must be considered to mass?
Is there no way to use eleLoad without consideration to mass?

the eigenvalus should not change with the addition of an element load. what is the loadControl 1.0 1 doing? if you are doing an analysis in between the eigen commands, the values may change if the model is nonlinear.

Dear Mr.McKeena

Thank you for your advice.
As you indicated, the analytical model had turned into be plastic by eleLoad.

>what is the loadControl 1.0 1 doing?
Sorry. "loadControl" is a procedure created by me.

It means....
integrator LoadControl 1.0
analyze 1
