Abstract:
Beam structure adapted to be subjected at least to a bending force determining along said beam structure an envelope curve of the bending moments which comprises at least one first part in which the bending moments are of the same first sign, at least one second part in which the bending moments are of a same second sign opposite said first sign, and at least one third part in which the bending moments can be of said first sign or said second sign or zero, said beam structure comprising particularly concrete, at least one first (11) body whose height and length define respectively the height and length of said beam structure, characterized in that said beam structure comprises a second (13) body connected laterally to the first body along the length of said first body,said second body being disposed at an upper end of the height of said first body in the first part of said curve envelope of the bending moments,said second body being disposed at a lower end of the height of said first body in the second part of said curve envelope of the bending moments,and in that said second body is continuous longitudinally and is disposed at a variable position along the height of said first body, from said upper end to said lower end in the third part of said curve envelope of the bending moments.
