Abstract

Truss (100) comprising- at least a lower stringer (111),- at least an upper continuous stringer (110) with length equal to the whole length of the truss,- a plurality of cores (112) connecting said lower (111) and upper stringers, said cores (112) being connected to the upper stringers at well defined geometrical intervals, with a constant pitch (p) along the development of the truss,characterized in that it comprises further, at the two ends of its own longitudinal development, additional upper stringers (114), integrally connected to said cores (112), the length of said additional upper stringers (114) being equal to a multiple of said pitch (p) and lower than the length of said truss.
