Determination of deflections of beams with corrugated web with the shear strain
Incoming article date: 10.01.2013This article is devoted to the analytical determination of deflections of beams with corrugated web. The reduced shear modulus which must be considered when determining the components deflection from of the shear strain in the beam with corrugated web is defined. Applying the energy method in the form of the Ritz, the problem of determining deflections with considering of bending strain and shear strain is solved. This article, as an example, is considered simply supported beam on both sides of constant and variable cross-section and are given to the final formulas according with three kinds of loading. The results of the calculation of the numerical examples for the three main shapes of corrugated web are submitted. Numerical results with great accuracy are consistent with calculations based on the finite element method.
