Pforce, 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

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.
