Embodiment Construction
[0073] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0074] A wind resistance method for a long-span suspension pipeline bridge, comprising the following steps, such as figure 1 Shown:
[0075] Step 1, establishing a finite element model of a suspension pipeline bridge with interfering cables, which connect the main cables and wind cables of the suspension pipeline bridge, and are used to limit the amplitude of the main cables and wind cables and increase the vibration of the suspension pipeline bridge Structural damping; according to the size and tension of the cable system, preliminarily set the tension of the interference cable;
[0076] The pre...
