![]() ![]() 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: ![]()
