Where does robot show the value of the base shear and the total vertical load on the structure

Thank you

Results then Reactions. look for Fx or Fy for base shear, Fz for vertical

What accounts for the difference between the Fx, Fy and Fz calculated in the reactions table to that calculated in the stories (reduced forces tab) table?

hi rafal and artur

i am wondering

is it possible to take value of seismic force at any direction (x or y )that acts on wall and coulmn from reduced forces tab ( results>>> story >>>reduced forces tab

because it is completely different from reaction results table

197.21+551.88=749.09

any idea

Looks like your filter is wrong.

The total Fx is the same, I think there are some nodes not being counted properly in the reactions table.

I don't think you can filter for bars, when you are actually after node reactions.

I have selected coulms at base level in order to know the total forces that acts on it

yes total Fx the same and = base shear but distributed forces to coulmn are wrong ??? how can i know distribution force to coulmn on reaction table as shown on reduced force tab

Hi Rafal and Artur
please

coud you confirm me is it possible to use reduced force tab instead of reaction table in order to know distribution forces to coulmn or wall at base level
