摘要：

On the basis of virtual work variations a new finite element with a variable crosssectional area along a generation, which due to numerical integration takes into account the variability of mechanical and geometrical parameters in cross-section was developed. In the process of test problem solving the correctness of the results, which allows to get this version of FE, was confirmed.
