Static Reversed-Cyclic Analysis

[nrojas]

Hi !!!

I want to do static cyclic analysis but with different displacement history in both direction. Is this posible? The Analyze.Static.Cycle.tcl only do cyclic analysis for the same vector of displacement for both directions. Please if some body can help me, I will appreciate it.

do something like this:

[code]
foreach {dU numStep} {0.1 100 -0.01 1000} {
integrator DisplacementControl $ctrlNode $dof $dU
analyze $numStep
}
[/code]

just vary dU and numStep in the list you supply, i.e. the {0.1 100 -0.01 1000 .....}

I have to do this in the analyze.static.cycle.tcl script?

I change the displacement vector including positive and negative values
like this:
set iDmax "0.004 -0.005 0.011 -0.015 0.0151 -0.017 0.0221 -0.025 0.0294 -0.03"; # vector of displacement-cycle peaks, in terms of storey drift ratio

when I run the program it give an error:

integer too large to represent.

What can i do to solve this error?
