The paper shows the main approaches to the calculation method of cross-sections of the structural element of the arch that meets the condition of reliability and the corresponding the minimum weight of the arch structure. The calculation is performed in the design of optimal arch designs, which is designing the structure so that all cross sections of the structural element of the arch of reliability was given, and the weight of the arch structure was the minimum possible.
The use of light arches with a given reliability saves metal and reducing the cost of the design and determines the prospects of applying such structures in buildings and agricultural buildings.

Key words: Cross-section of the arch, the cross-sectional area of the arch, the length of the cross section of the arch, a structural element of the arch, the margin of safety, reliability and durability of the steel structure, the stability of the metal framework, independent of the random variable.
