Features for calculating beams with a thin transverse corrugated web plate considering bending-twisting forces

The article describes the features of work beams with a thin transverse corrugated web plate. Exponential fractional regression is presented, which allows one to estimate relative height plate sections working together flanges, obtained by authors based on an analysis numerical experiments. Based work, method proposed for describing stress state arbitrary cross-section I-beam (the profile corrugations triangular, trapezoidal, sinusoidal) bent in plane and compressed longitudinal direction, using theory thin-web platted elastic rods Professor V.Z. Vlasov. calculations are given determining bending-twisting forces (local bending moments bimoments arising from action main forces) cross section.
