WebOct 22, 2024 · Timoshenko beam theory is commonly used for the calculation of beam deflection when the shear deformation is considered. The Timoshenko beam theory addresses the shear deformation using a shear form factor. The shear form factor compensates for the assumption of a constant shear strain over the cross-section. WebIn this paper, the dynamic response of a simply supported beam subjected to a moving load is reinvestigated. Based on a new beam theory, slope inertia-based Timoshenko (SIBT), the governing equations of motion of the beam are derived. An analytical solution is presented by using a coupled Fourier and Laplace–Carson integral transformation method. … richard maxon daily mail
