The article presents an analysis of static and strength of all supporting elements livestock building from turn of the century XIX and XX. It was analyzed former solutions of materials used for floor support structure. Research were conducted in laboratory conditions due to tensile strength. On the basis of research results, all elements analyzed statically and strength. Due to the high degree of failure of building, in the design stage it was analyzed the possibility of using the existing supporting columns of the supporting structure under the proposed adaptation of the object on the mushroom farm.

Keywords: steel structures, reinforcement, analysis of mechanical resistance.
