Webbcompared to solid section beams. In particular the proﬁle warping occurs combined with elastic couplings involving bending and twisting; other local effects arise as well. Therefore, the recognized classical beam theories like Euler–Bernoulli and Timoshenko cannot be trustworthy to analyse thin-walled members. Webbwarping constant of CW steel beams based on experimental tests results. The study confirmed that the torsional section constant may be calculated using the same method as beam with flat web. Sayed-Ahmed [8] concluded that the resistance of CW steel beams to lateral torsional buckling is higher than those with flat webs by magnitude up to 37%.
