| Abstract: | Three methods for cable calculation, that is, catenary method, parabola method and finite element method, are introduced in this paper. The formula of elastic stretching is derived for the catenary method, followed by the accurate formula for cable calculation. In conjunction with the practice of cable hanging in the construction of Hongshan Bridge, three representative cables are analyzed with the three methods. Finally, the advantages and disadvantages of the three methods are compared. |
