The study deals with the behavior of bolted joints between the wings and the fuselage of an airplane. To study this complex structure, we use a classical finite element code with a simplified model (called macromodel) to avoid a large number of degrees of freedom implied by a fine discretization of the local geometry and non-linearities (contact, friction). During previous studies, the macromodel was constructed by simple springs. The use of this type of macromodel in assembly simulations enables to define the most loaded bolt. However, these simple springs do not allow to take into account non-linearities such as contact with friction. To face this problem, a new macromodel is considered.
