La zone de liaison (31) peut être reliée à la zone de liaison (31) d'une autre section (13, 15) de charpente. La section (13, 15) de charpente contient respectivement deux sections de membrure supérieure (21A, 21B) et deux sections de membrure inférieure (23A, 23B) qui s'étendent de manière parallèle les unes par rapport aux autres dans le sens longitudinal de la section (13, 15) de charpente et sont reliées entre elles de telle manière par des entretoises de liaison (25) qu'un espace (71) de forme parallélépipédique est jalonné par celles-ci. Les sections de membrure supérieure (21A, 21B) et les sections de membrure inférieure (23A, 23B) comportent une section transversale de forme tubulaire. Les sections de membrure supérieure (21A, 21B) et les sections de membrure inférieure (23A, 23B) sont configurées dans la zone de liaison (31) de manière à passer de la section transversale de forme tubulaire à une section en forme de I.
