It was established that they are different, because they are obtained using different initial positions, and give underestimated values of the optimal height of the beam and, accordingly, overestimated values of the mass of the structure. An improved algorithm for assigning the height of the beam has been developed, which, with limited wall and shelf thicknesses, practically ensures the condition of the minimum weight of the structure Product Description popup.authors popup.nrat_date 2023-01-07 Close
