What is it about?
This paper presents a guide to the analysis of preloaded bolted joints made using multiple bolts. A practical method of analysis of loads and stresses in individual bolts and dowels, along with flange bending and thread shear in tapped or threaded holes is developed.

Why is it important?
The article brings together a number of concepts and links them into a practical design analysis process that is applicable for many cases of preloaded bolted joints and are adequate to demonstrate the structural integrity of each element of the joint.
Perspectives
I hope that the article raises awareness of preloaded bolted joints and shows that each joint is a complete, complex, system and that the bolts cannot be considered in isolation.
