Stress and Strain State in Beams with Corrugated Web and Their Use in Hydraulic Engineering Structures

The paper presents a methodology for calculating stress and strain state in beams with corrugated web. The methodology has been developed by the authors and is simpler than the existing method of calculation. While calculating, the authors offer to change the corrugated web for a plane orthotropic plate with the reduced modulus of elasticity showing the same non-rigid characteristics as the corrugated web. The given mathematical notation calculates the reduced modulus of elasticity of a plane orthotropic plate simulating the performance of the corrugated web. The calculation in the paper is made for a beam with corrugated web used as a cross-beam plane gate in hydraulic engineering structures. The calculation results got by the authors while using their methodology are compared with those obtained by the finite-element method (FEM).
