Abstract (en)
[origin: WO9109252A1] A composite structural member (10) is fabricated by springing together two generally 'C' section components (11), each of which has a web (12) with a pair of ribs (16) extending along it, upper and lower main flanges (13) terminating at their edges in sub-flanges (14) directed towards each other, and each sub-flange terminates in a lip (15a, 15b) which is directed back towards the web (12). The lips (15a, 15b) of each component engage respectively outer and inner surfaces of the ribs (16) of the other component, thereby inhibiting displacement of contiguous flanges (13), and maintaining a high moment of inertia which inhibits excessive deflection of the member (10) under load.
