This command is used to construct a StaticIntegrator object of type LoadControl
integrator LoadControl $dLambda1 <$Jd $minLambda $maxLambda>
$dLambda1 |
first load increment (pseudo-time step) in the next invocation of the analysis command. |
$Jd |
factor relating load increment at subsequent time steps. (optional, default: 1.0) |
$minLambda $maxLambda |
arguments used to bound the load increment (optional, default: $dLambda1 for both) |
The load increment at iterations i, dLambda(i), is related to the load increment at (i-1), dLambda(i-1), and the number of iterations at (i-1), J(i-1), by the following:
dLambda(i) = dLambda(i-1)*Jd/J(i-1)
