Dear all,
I would like to ask you:
1) I was checking the Plaxis3D Structural Verification for Plates and Shells (Plates:https://communities.bentley.com/products/geotech-analysis/w/plaxis-soilvision-wiki/45502/bending-of-plates Shells:https://communities.bentley.com/products/geotech-analysis/w/plaxis-soilvision-wiki/45505/performance-of-shell-elements) and noticed that both verifications consider the plate self-weight as zero. Using the same models I considered the self-weight of the plates and the results were not the same. Using the plate self-weight it was necessary to multiply the max moment by the length of the plate to get the correct value. Why this difference? I believe is due to the thickness (d) that I am considering in the plate properties that must be in accordance with the desirable load of the plate. But I would like to confirm it.
2) I am modelling a vertical tunnel shaft. I am a little bit confused with the discussion in "">communities.bentley.com/.../plaxis-3d-plate-output-unit-kn-m-m" about the integration of the results. It is ALWAYS necessary to multiply the moment results by the plate length (perpendicular to the moment)? Or this is applicable only in cases that I want to simplify and turn out the plate into a line?
My model is illustrated below. This is only one panel of the shaft. This panel is 5m wide and 50m deep. The M11 value that PLAXIS is illustrating is the final value or do I need to multiply it by the length of the panel?
3) For the Plates results PLAXIS gives the M11, M11 min and M11 max. How does PLAXIS calculate the M11?
Thanks!
