Abstract. An engineering estimation of accuracy of existing strength estimation technique has been derived for forced vibrations of framed structure. It has been shown that existing strength estimation technique essentially lowers the values of dynamic loads and stresses in oscillated structures, and the smaller is resistance of medium, the lower is strength estimation with existing strength estimation technique. The recommendations concerning improvement of existing technique have been proposed. The proposed approach, reported in this article, can be useful for students, university lectures and practical specialists in mechanics of materials.

Keywords: framed system, forced vibrations, strength estimation, parameters’ influence, computational technique.
