FIELD: machine building.
SUBSTANCE: invention relates to the field of transport machine building. Vehicle structure has section containing first and second elements passing in longitudinal direction. First element faces the inner side of the vehicle, and the second element faces the outer side of the vehicle. First and second elements form a closed space. Section comprises one or more first and second tubular reinforcing elements located in closed space. First and second tubular reinforcing elements have longitudinal elongation passing in longitudinal direction. First and second tubular reinforcing elements are corrugated and contain corrugations. Crimps of tubular reinforcing elements contain annular ridges and annular grooves. Second tubular reinforcing element forms the inner space. First tubular reinforcing element is located in the inner space formed by the second tubular reinforcing element.
EFFECT: possibility of deformation of structure for shock absorption is achieved.
