Abstract
The paper gives a brief review of works describing bending torsion analysis of beams with corrugated web. The authors put forward a solution specifying V. Vlasov's famous thin-walled bars theory which is generally used to calculate stress-strain behaviour of beams with corrugated web bending torsion. The specification lies in the following: the researchers measure flexure-torsion characteristics of the cross-section while increasing pure torsion moment of the cross section by means of introducing equivalent flange thickness into calculations. To check the efficiency of the introduced method the authors calculated five beams with sinusoidal corrugation for two concentrated forces action. The paper introduces the results of these five methods of beam calculation including the one developed by the authors. The obtained results showed that the tension value in each case is almost the same (with maximum 7% difference in rates). The research also determines the scope limitations of the authors’ specified theory.
