FEATURE: Multi-support Input for EE-UQ and WE-UQ

[nealleehit]

Hi,
Please kindly consider that provide a solution if we want to do an opensees multi-support input analysis for spatial structures.

BTW, we have considered about that, multiple input function might be also required in WE-UQ.
The SIM panel might be OK to do the multi-support input setup for models. however, we still can not provide Strong ground motions in EVENT panel.
If you can develop that function, and at the same time can provide an adaptive solution during this developing period, we appreciate that.

Thanks a lot.
Best,

We will consider multi=support for EE-UQ for future inclusion.  is this specifically for bridges or do you envision it's use in buildings?

Can you provide more details as to why you think it should be in WE-UQ.

As to an alternative solution while we develop it, you can use quoFEM.

Thanks.
yes, it is for spatial span bridge or long span structures.
i am not a man on wind things. so, for WE-UQ, did it consider the spatial coherency of the inputs of wind loads at different heights or positions?
basically, they might be the same multi-input problem.

We are using quoFEM alternatively. however, it is still not suitable since it can not process the maximum responses very well just like EEUQ. The sensitivity of parameters is what we need to analyze.
We think it is because the quoFEM can not process the following scripts,

set nodeIn [open node.out r]
set forcesIn [open forces.out r]

while they are available in EEUQ, as in the example.

Best,

Ning.

Share some solutions for the issues before.

the quoFEM is mainly driven by OpenSees which is based on tcl/tk

the structure model tcl script should have a wipe command or record command at the end of the file to force OpenSees finishing the recorder writing into files.
after that ,the command
set nodeIn [open node.out r]
set forcesIn [open forces.out r]

can be processed correctly.

Best,
