![]() ![]() ![]() Westok software (Westok Cellbeam, developped by SCI: ).FBEAM automatically finds the most economical cellular beam designĭesigners of cellular beams will welcome the ability to optimise their designs in the latest version of cellular beam manufacturer Fabsec’s free software.īeam Wizard, launched a year ago in version 3.1 of Fabsec’s free FBEAM software, “takes the donkey work out of designing a cellular beam,” says Head of Software Development Guy Rutter.ArcelorMittal software (ACB+, developped by CTICM: ).More extensive calculations are possible with: Arcelor Cellular Beams: Detailed Technical Description. Design of composite beams with large web openings (SCI P355). Resistance of tees in Vierendeel bendingĪlso note that the deformation will be larger than calculated with Diamonds because of the effects for Vierendeel shear deformation along the openings. This can be calculated with a Vierendeel (framework) analogy.Ī new Eurocode part is in the making about these beams (EN: Steel beams with large web opening).Buckling of compressed tee due to global bending.These additional checks are mainly local and relate to the tee section (part of the web above and below the opening) and the web post (part of the web between two openings). Next to the usual checks from EN (implemented in Diamonds), the additional checks mentioned below also apply (not implemented in Diamonds). If not, also adjust the cross section classification. ![]() Check that the cross section of the tee section (part of the web above and below the opening) is less conservative than the cross section of the entire beam.curve c (=0,49) for double symmetric castellated beams (circular or hexagonal openings) made from hot rolled parent sections.Adjust the imperfection factor for lateral torsional buckling to.Adjust the properties I y, W y (elastic and plastic), I T and A Vz (substract opening from the properties of the gross section).Find the parent section in the Diamonds section library and adjust its height H.For the global analysis (determing M,N,V in a construction) I-shaped cross sections with reduced properties (calculated near the openings) can be used: ![]()
