In a gusseted base, when the end of the column is machined for complete bearing on the base plate, then the axial load is assumed to be transferred to base plate
When the axis of load lies in the plane of rivet group, then the most heavily loaded rivet will be the one which where, Fa is the load shared by each rivet due to axial load and Fm is the shearing load due to moment in any rivet.
A.
is at the maximum distance from CG of the rivet group
B.
is at the minimum distance from CG of the rivet group
C.
gives the maximum angle between the two forces Fa and Fm
D.
gives the minimum angle between the two forces Fa and Fm
