Hi all,
I would like to know how to input each pressure tap data (pressure time series at every point from the wind tunnel) in the SAP 2000 model?
I have 500 locations on a building model and at each location, I have pressure time series data. I would like to apply pressure time series data at each point as a load in SAP2000. I will be grateful to all of you if you could anyone help me how to give this input in SAP2000.

Thank you

Well this kinda sounds fun. But let me warn you its a ton of work and I can't verify that it's even possible.

But here is some of my thoughts that I would consider while trying to approach this problem.

1) Pressure needs an area to act over. That means you need to come up with some kind of tributary mesh of surfaces to each pressure tap. Not a trivial task.
You must decide whether you want to vary the pressure or vary a single point load. Either way you need to capture the effect of surface tributary area to each pressure tap.​
2) Now you could use SAP's time dependent load functions to create a time series of the loading for each location. Not a trivial task.
3) You can use SAP2000 linear combination feature to superimpose each load case into a single load case. This is actually a trivial task lol.

The hardest part would be managing all of the time series data, and keeping track of the tap locations, and properly applying the pressure as I discussed in step 1.

If done manually through SAP gui, it will be quite a bit of work.
I would probably look to pre-process as much of the data as I could, perhaps even look into SAP API. With that you could potentially load up your data into python or something and pre-process it and push it out to the SAP model programmatically.
