An Improved Beam Element for Beams with Variable Axial .

By adding rotary inertia and shear effect into Euler-Bernoulli beam, Timoshenko beam is more accurate than Euler-Bernoulli beam, especially for thick beams. In this study, the simple Timoshenko beam element will be improved to consider the variable axial parameters, and it can also be reduced to Euler-Bernoulli beam element.
