RISA-3D and the PCA design coefficients
(OP)
I am trying to compare results from the finite analysis program RISA-3D to the plate coefficients in "Rectangular Concrete Tanks" published by PCA. All of the results from the RISA run seems to be lower than those listed in the PCA charts. Does anyone have any suggestions about how to model the plate? i.e. how thick, mesh size etc.?
Or has anyone else tried this exercise?

The FE results also assume a non-cracked section if you simply enter a constant thickness throughout your model. Does the PCA document indicate any assumptions as to cracking and loss of stiffness?

This is why I am concerned that I am not getting results closer to the coefficients listed in the PCA charts.
