Abstract
After numerous surveys during the company of modernizing of the milk - commodity farm, a planning phase of the reconstruction of the objects came. It’s required to perform verification calculations to determine the need to strengthen the structures according to their actual state. Buildings, engineered by the requirements of the previous TNPA, should be checked with the current regulations. The comparative analysis of calculations of the reinforced concrete structures were held according to SNiP 2.03.01-84, SNB 5.03.01-02, TKP EN 1991-1-3-2009 in the present work. The major differences in the determination of the values of resistivity of concrete and rebar, as well as, changes in safety factors of stress were revealed. Also, differences in the determination of the normative values of snow loads were identified. Also, there were identified differences in the determination of the normative values of snow loads. The calculations were held according to presented methods with determination of safety factors for structural strength.
