[0040] Example 1.
[0041] 1 Standard suspension bridge main cable based on the present invention
[0042] Due to the difference in the length of the main cable of the suspension bridge, the number of parallel steel wires in the strands can be divided into 61, 91, and 127 according to needs. In this example, 61 standard strands are used for illustration.
[0043] 1.1 Main cable specifications
[0044] In this example, the number of cable strands used for the main cable is 19, of which, except for the central cable strand, the rest of the cable strands are all stressed strands, a total of 18, see figure 1 .
[0045] 1.2 Strand strand structure
[0046] The stress cable strands are all parallel steel wires except for the central ventilation steel pipe. The lengths of the parallel steel wires and the ventilation steel pipe are the same, which are usually related to the size of the applied bridge. The cross section of each strand is a regular hexagon, see figure 2 .
