ON THE SHEAR STIFFNESS OF BEAMS WITH HETEROGENEOUS CROSS SECTION

Abstract

A number of shear correction factors have been proposed for a century. In addition to the classical elasticity, the numerical methods for the computation of the shear correction factor for general complex shape cross-sections are also developed recently based on the discretization of stress field of the cross-section. However, the method for the estimation of the shear stiffness of the heterogeneous beam has not been reported so far. In this paper, exploiting the averaged method of heterogeneous beams by the authors, a computational method for the shear stiffness of the beam with the heterogeneous cross-section is proposed.
