Numerical Study on the Behaviour of Built-up Cold-Formed Steel Corrugated Web Beams End Connections

Corrugated web beams made of cold-formed steel components represent an economical solution for structures, offering high flexural capacity and deformation rigidity. For conventional corrugated beams, thick plates the flanges thin sinusoidal sheets web, elements can be joined by standard bolted end-plate connections. In case thin-walled only, additional are required to accommodate shape position profiles. A large experimental program was carried out on elements. One objectives determine these influence several parameters response beam, but also very important were end connections beams. The recordings obtained from tests used validate a numerical model. Based validation model, finite element analyses performed study four solutions facilitate assembly, optimise number bolts, increase Although connection improved assembling reasons with presented solutions, overall is limited subjected compression that lose their stability.
