N - normal force, positively directed downwards
Nmin - the minimum normal force from which the shear force is determined
M - moment in the plane of the column
Q - horizontal load
ls - length of the base plate of the column
bs - column base plate width
c - distance from the axis of the column to the bolt; the bolts are considered to be symmetrical; cannot be more than ls / 2
n - number of bolts on one side
Bolt diameter - select from the list
Bolt type - choose from the list: with bend, in the anchor plate, blind or removable, straight, tapered (spacer).
Bolt steel grade - choose from a list of two possible options according to SP 16.13330.2011
Concrete class - select the concrete class of the foundation from the list.
Coefficient k0 - select from the list; coefficient depending on the type of structure, type of load and type of bolt.
Endurance test - check or uncheck the box; performed in the presence of dynamic loads. When selected, the coefficient k0 automatically takes on the value for dynamic loads.
Coefficient α - select from the list; depends on the number of loading cycles.
