Dear All,
Can we model building slabs as node to node anchors in Plaxis 2D?
Dear Jamal,
I would take it down to the basics: what does a node-to-node anchor simulate?
A node-to-node anchor is a linear structural element (also considers an out-of-plane spacing in 2D) which can handle only axial forces, no bending or shearing and has no interaction with the surrounding soil or rock.
Typically a slab has a thickness (and a width) which would not be captured via the node-to-node anchor. Also, it is typical that a slab would bend, which is also not handled with the node-to-node anchor.
Considering the above I hope you are now aware of what you can simulate with this element and whether it is sufficient for what you want.
Thank you, this is clear, I appreciate.
In addition Stefanos Papavasileiou,
I was investigating in ways to obtain lateral seismic earth pressure from basement walls. One of the ways available is, to take a cross section and investigate effective/total stress (sigma xx), check interface faces total/effective. I was wondering if I could use a method where we obtain the forces on the lateral elements (e.g slabs) and divide them by effective area (depth between elements * out of plane dimension to obtain the pressure in force/m2 form.
