liquid storage tanks and seismic loads

[sanjuan100]

Hello,

Can anyone let me know please whether Robot carries out seismic analysis and calculates the action from a liquid (e.g. water, oil) in a storage tank following EC8-4 Annex A? or what would be the best way of doing this analysis in RSA?

Thank you

Thanks Rafal, but this doesn't help. The issue in the link is a modelling issue.

I was refering to modelling the seismic forces of the fluid, I understand this is different problem to defining standard masses for the structure and from loads.

I refered to EC8 Part 4, though ACI has similar documents. Does Robot model the convective and impulsive pressures from the fluid? if so how can i do that?

thank you

No.
