In a building in which pillars have a rotational restraint, we will have, apart from axial forces, moments and shear forces. The moment on the head of the pillar is not the same that reaches the lower slab (frame effect explained in this other article). This article explains the advanced user the origin of the values of these on-head forces (the ones exported to STATIK). Basically, they are the reaction on each storey using ‘POINTS’ (not surface).
- The forces on the head, the reactions and the forces on the base are shown in the Building (Nu,Vv,Vw,Mu,Mv,Mw) and they can also be seen in STATIK (identical values because they are imported):
One must be careful because the slab on CEDRUS has a support modelling that works much better with the negatives and that is the ‘Area’ support instead of the point one. This is the default support, that enhances the behaviour of every slab.
With the ‘Area Support’ , the reactions of CEDRUS will slightly differ from the values of STATIK because the values that will be exported to STATIK will continue to be the ones considering the support as a "point".
