Abstract

This article deals with the straightening of flat curve lines lying on a plane. To straighten the curve, a box curve of a flat arch is built according to its width AB and the height of the os. The hollow roof box curve consists of four circular arcs. To straighten the arch, you had to define the length of each circle arc. The authors of the article applied the method of small chords. As the name itself shows, the method is that a broken line is inscribed into the flattened flat curve, the links of which represent small chords of the curve. Thus, the straightening and determination of the length of box flat curves of flat vaults find application in the construction of arches of bridges, entrances to buildings and metro, etc.
