Hi!
I have 4 nodes on the centers of 4 load transfer surfaces which simulates a base plate.
In the UI I have checked the boxes in the 4 nodes to enable punching design, and run the concrete design but I get the error "One or more nodes have a dimensionless node load. Punch calculation is not allowed."
From Punching Shear Design in RFEM 6 it says "The concentrated load at these nodes can be introduced by columns, concentrated force, or nodal supports". The load transfer surface has a pressure load of 6090 kPa (2985kN total force) so it warrants a punching shear check, but unsure if rfem6 will check it for a pressure load or if it has to be a node load? The node is an integrated object in both the main (standard) surface and the load transfer surface. I'm not 100% sure what constitutes a 'concentrated load'.
I can email or message through the model file if that will help 
Thanks
