ABSTRACT:
A rivet splice that holds an upper and a lower sheet metal end portion together includes at least one row (6) of rivets that is subject to dynamic loads and a further row (7) of rivets that holds the sheet metal end portions together so that a limited sliding motion between the sheet metal end portions is possible. The further row (7) of rivets is positioned between an end edge (4A) of an upper sheet metal end portion and the at least one row (6) of rivets. The limited sliding motion provides a load relief of the at least one row of rivets thereby reducing the starting of cracks at the walls of the rivet holes and impeding the spreading of cracks.
