CALCS	BAS004 BOLT GROUP

NOTATION
Xcoord	coordinate, bolt, from datum
Ycoord	coordinate, bolt, from datum
Dia	diameter, bolt
Px y	force, applied to group, parallel to x (y) axis
Mz	moment, applied to group,parallel to z axis
Xl Yl	coordinates, point of force application
Px Py	force, applied, parallel to x (y) axis
P	force, vector sum

APPLICATION

Bolt or rivet groups joining two plates and carrying loads in the idealised common plane.
Maximum number of bolts 50.

OUTPUT

Bolt shear force.
Problem definition plot showing bolt positions & vectors indicating relative stiffnesses.

THEORY

Roark5, Page524

GUIDANCE

The program calculates bolt shear force on the basis of bolt relative diameters. While bolt CSAs are an alternative basis, this is not invoked in the present program. Either may be justified having regard for the more significant assumptions of the analysis.
