1. Various assemblies

A joint is a bolted (or riveted) assembly of thin-walled, flat or quasi-plain parts, subjected to forces located in the joint plane and to moments normal to this plane.

There are two ways of transferring forces from one part to another:

• by shearing the fasteners at the joint plane of the assembled parts. Fasteners are then fitted with very little play (< 2% of diameter) or with a tight fit (interference);

• by adhesion between the clamped parts. The fasteners are then installed with play, and the coefficient of friction between the assembled parts and the prestressing force installed on each bolt are the characteristic parameters of the assembly.

Two classic arrangements are used:

• single lap splices...
