A composite beam that comprises a web (21) having a corrugated-shaped profile, with aligned parts (23, 22) in two parallel planes (27, 25) in the longitudinal direction and tilted parts (29) between them; two flanges (17, 19); a first element (33) of C-shape and a second element (43, 53, 63) of beam-shape, such as C or Z, each of them having webs (35; 45, 55, 65) bonded to the parallel parts (23, 22) of the corrugated web in one plane (27, 25) enclosing the web (21) between them, and having the caps (37, 39; 47, 49; 57, 59; 67, 69) of said first and second elements bonded to one or two additional single flanges (7, 9) or bonded between them to form the beam flanges (17, 19). |
