Wind load on dome

Anonymous — Tue, 26 Nov 2019 10:36:49 GMT

Hi all,

so I calculated manually wind loads on my dome (using EC1) but I don't know how to put it on robot structural plz if you have any idea or advice

Did you try the wind load simulation(CFD) . On Loads/wind load simulation/Generate wind loads.

I tried a test model here and the load distribution looks like the picture you sent. You may probably have to adjust the load values manually to follow eurocode rules.

You just have to pay attention to some details when building the model.

1- RSA CFD only generate loads on flat panels . So each piece of the dome is a panel.

2- set a mesh size larger than the panel dimensions , to have just one FE per panel. Set something absurd like 20m.

3- Watch the video to see how I modelled the dome

test model attached

thank you for your help but actually I have like this (pic) so I'm struggling to define manually the wind load (using 3p or 2p..)

Can you send this model?

Zip before attaching.

Why don't you use the wind load generation on this model?

I'm trying to apply all wind loads like in the picture, I can't use the wind load generation on this model because robot takes the value of the coefficient Cpi different from the one that is in EC1.
