(material) imperfections (e.g., residual stresses). Besides, due to high width-to-thickness ratio of I-section steel members, local buckling occurs [ 2 ]. These imperfections considerably affect the behavior of steel members and reduce their buckling

An actual problem of fabrication of pre-stressed concrete prefabricated elements is presented in this article. The steel form could be more than 100 m long. Inserting the polystyrene plates ten or more prefabricates can be produced in one step. The horizontal deformations represent a special problem. The simplification of the elastic support as the friction effect is introduced. The non-linear solution has been used.
