Webstiffness element for modified Timoshenko beam theory. For the purpose of numerical simulation, the influence of boundary conditions and slenderness . on the accuracy of axial force identification, element mass and stiffness matrices are needed for . the modified Timoshenko beam theory. As proposed by Friedman and Kosmatka (1993) to avoid WebTo evaluate the accuracy of our viscoelastic Timoshenko beam model, three more models were constructed based on the combinations of these two aspects. For the first aspect, the Euler and Ti-moshenko beam models were compared at a fixed loading rate. For the second aspect, the elastic and viscoelastic models were compared at different loading ...
