Design of Double Arch in Steel Structure Engineering

The steel structure oval tube and double arch consists of two oval tubes connected by spacers. This design has several advantages. If the broad side of an oval tube is welded, the contact area of ​​the weld will be larger than that of a welded round tube. Choose the oval tube, you can weld high quality and quality parts, the two-piece combination is perfect and safe welding. Oval tubes provide excellent structural engineering in the Datong area. At the same aperture, an oval tube is 4 times stronger than a round tube and 1.5 times stronger than a rectangular tube of the same size. Therefore, more steel must be placed in circular or rectangular tube buildings to meet wind and snow loads. Due to the shape of the oval tube, the oval tube resists a highly compressible rectangular tube or a square of the same size, the ellipse enters the plastic limit (class 1 or 2), and the rectangular or square tube does not exceed the elastic limit (class 3). The oval tube has a wide flat surface on which the film is placed. There is no edge, it combines with the tension of the membrane, creating only friction points and wear, such as square or rectangular tubes. Extend the life of the movie. Straight columns are rectangular or square, connecting two oval tubes to form a double arch. The angled support members are welded to the flats of the oval tube. By reinforcing the supported straight struts with double arched struts, each significant deformation of the Chongqing steel structure creates a weak point of resistance when considering folding paper clips. pillar phenomenon. identical. In each arch section, use calipers to install 5 sections later to form a complete arch. The caliper is better than other types of connections and its shape is also visible in other constructions, which gives it excellent strength. All surfaces between the end yoke and the yoke are welded and have imperfections.
