Wind Engineering (WE-UQ) / numeric assignment for the pset command
« on: April 27, 2021, 07:26:27 PM »
Hi,

When I use the pset command with an expression instead of a number like below:

pset mass_roof [expr 40.06/(2.*6.*12.)] 

the "mass_roof" random variable doesn't appear in the tool. I can replace the expression with a number for this specific case. But is it possible to be able to have expressions as inputs as well?

Wind Engineering (WE-UQ) / correlation between RVs in LHS method
« on: April 17, 2021, 03:45:35 AM »
In the current version, are the RVs uncorrelated? Does the shuffling approach in the current LHS sampling method configured in a way to prevent spurious correlations between RVs?

ok thank you, I saw the static analysis parameters in the example.tcl file now. But I don't understand what this means:

integrator LoadControl 0.0
analyze 1

This is an OpenSees question, I guess. But I don't know what a load factor increment of zero does. Does this take the first input in the wind loading time series and apply that statically to the building? If yes, then the value assigned to "staticWindLoad" in the event.jason file is unused.

General Questions / Re: Running on DesignSafe
« on: April 12, 2021, 06:07:52 AM »
Just wondering how many nodes and processors is ok to use when running on DesignSafe? I think I remember 64 processors per node from a WE-UQ video tutorial. But I don't remember how many nodes we can use.

Thank you so much for you swift response. I am referring to the definition of the analysis engine parameters in the FEM module of the WE-UQ tool. They include "analysis", "integration", "algorithm", "convergence test", and "solver". But I don't see a constraint option. I just wonder how constraint equations are handled by the program, and whether or not I need to include the constraint command in my tcl file when I am uploading an analysis script?

Hi,

I'm just curious to know why isn't there a "constraint" section in the FEM section of WE-UQ?

Thanks,
Azin

Well that is great! I didn't know about that, so I have added a ramp at the beginning of my loading histories to prevent sudden dynamic impact.

I couldn't find anything in the example.tcl file about "StaticWindLoad". I am just wondering what is the timeSeries type using which this load pattern is applied to the structure? Is it a linear timeSeries to create a ramp? If that is the case, then it's so nice since I don't have to add the ramp manually to the loading histories.

This is great, thank you. Is the "StaticWindLoad" defined within each load pattern a load coefficient that will be applied to the data points in the corresponding time series?

Wind Engineering (WE-UQ) / existing event file format

Hi,

What is an example of a valid existing wind event format?

Thank you,

When I use the nodes on the leaning column as the "centroid" and "response" nodes, the problem is resolved since I don't have panel zones on the leaning column, and I don't need to skip any nodes in between, which was the case when I was using the left column line as the loading and response line.

For this model, I use the nodes located at the bottom of the panel zones, throughout the left column line as centroid nodes as well as response nodes. Therefore, not all the nodes on the left column line are included in loading and response monitoring (e.g. nodes on the panel zones are not included). Could this the problem?

I used the WE-UQ three-story example, and eliminated one of the nodes to see what happens. i.e, instead of 1 2 3 4 as centroid nodes, I wrote down, 1 2 4, and modified the recorder and postprocess files accordingly. So with this conditions, no recorders were generated for me. That is why I assumed that either all the nodes on the column line should be included in the centroid and response sections, or I am modifying the recorder and postprocess files incorrectly.

That would be great. I appreciate it. I have attached the code to the message.

Thanks,
