METHOD OF SEARCHING A RATIONAL STRUCTURAL FORM INCLUDING OPERATIONAL EXPENSES
In this report proposes a method of searching for a rational structural form of metal structures with the accounting of operating costs. Choice of rational structural form of metal structures to avoid unwanted costs both during construction and during the operational phase. The article highlights the main challenges for the goal. Described in detail the method of calculation of longevity of elements of metal structures, and selection of the necessary elements of the cross sections for the required life of the structure. An example of the choice of constructive form of the metal farm from round tubes at its operation with the presence of the protective coating, without coating and without regeneration.
