Disclosed is a hollow profiled element, particularly for a lattice tower, comprising a first profiled part and a second profiled part. The cross-section of the hollow profiled element is designed such that the first profiled part has two legs and the second profiled part is disposed between the legs of the first profiled part in such a way that one final edge of the second profiled part is connected to one leg of the first profiled part while the other final edge of the second profiled part is connected to the other leg of the first profiled part in order to form a closed hollow cross-section, said connections being such that a partial section of the respective leg of the first profiled part projects from the joint. The first and the second profiled part are designed such that the ratio between the two area moments of inertia about the centroid axes of the cross-section of the hollow profiled element ranges between 0.9 and 1.6.
La présente invention concerne un profilé creux destiné en particulier à une tour de charpente, comprenant une première partie profilée et une seconde partie profilée, la section du profilé creux étant telle que la première partie profilée présente deux branches et la seconde partie profilée est disposée entre les branches de la première partie profilée de sorte que, pour former une section transversale creuse fermée, une arête terminale de la seconde partie profilée est reliée à une branche et l'autre arête terminale de la seconde partie profilée est reliée à l'autre branche de la première partie profilée, à savoir de sorte qu'une section partielle de la branche respective de la première partie profilée dépasse par rapport à l'emplacement de liaison, la première et la seconde partie profilée étant conçues de sorte que le rapport entre les deux moments d'inertie de surface autour des axes de centre de gravité de surface de la section transversale du profilé creux vaut entre 0,9 et 1,6.
