Hello. I made the static calculations of the steel industry structure in sap2000 with all the necessary combinations including earthquake forces. However, while calculating the single foundation in idecad, I modeled the normal forces and moments of shear force, including earthquake forces, in the idecad single foundation and affected the reactions on the columns separately as point loads. Here I do not understand; After applying the forces to individual columns, idecad calculates the singular basis according to which combinations. Because in sap2000, the reactions have already been increased. How does idecad calculate the singular basis calculation under these reactions. Can you share a sample project related to this?
