underground rectangular water tank design

[Anonymous]

 its showing some warnings...plus i need wall RC design results to compare with the staad model......SP is soil pressure and Wp is water pressure.....can any one check the model...if any mistakes r there pls info me soon.....i need area of steel required in each wall....i have give planar support.....because i staad pro i was thinking to give spring support....can we give spring support in robot structural analysis....if yes....pls info me soon.....

Hi @Anonymous

Yes, you can define planar supports in Robot. I'd suggest watching the recording of the 5th RSA webinar which is available from here.

its showing some warning....can u check the model which I have attached...

About some material....

Hi @Anonymous

I can't see any calculating your model. Could you attach its screen capture?

i attached the warning its showing.....i am publishing a paper of comparative study between staad pro and RSA......i will come back to u ...once the paper is done...if u can give any feedback ...it will be good....

Hi @Anonymous,

Your soil pressure (SP) can also be modeled better under special loads rather than uniform planar loads.

I also think you can refine your mesh to a better degree. I like using;

a = 2h ; 1/10 x l ...whichever is smaller. Where a is element size, h is plate thickness and l is the shorter span of the panel (from a post I saw on this forum  ) https://forums.autodesk.com/t5/robot-structural-analysis-forum/finite-element-mesh-size/td-p/3752226 props to igos

If the material properties assigned to the panels are correct then you can ignore it.
