Embodiment Construction
[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0027] see Figure 1-2 As shown, the present invention is a method for identifying the internal force of the main cable of a long-span suspension bridge:
[0028] 1) Since the flexural stiffness of the cable is very small and has no fixed shape, the following assumptions can be used for the calculation of the cable structure of the suspension bridge: ① The cable is ideally flexible and cannot resist compression or bending; ② The cable material conforms to Hooke's l...
