First, we must carefully determine the number of bridge layers, width, type of support points, spacing, and the specific distribution of cables on each layer of the bridge. Secondly, the uniform load of each layer of cable is calculated according to the physical engineering formula, so that the model of the bridge frame and some related specifications can be determined initially. Then, we need to strictly calculate the strength of Baotou cable tray in strict accordance with the maximum total uniform load value of the cable . The verification formula is Q use = q1 + q2, where: q1 refers to the uniform load of the cable; q2 is the uniform load equivalent to the weight of a person when we are considering cable laying or maintenance. Based on the above-mentioned initially determined bridge model, specifications and fulcrum distance, check the distance and bridge model repeatedly by consulting relevant data until the load is met Requirements. Finally, the deflection value is determined. The maximum allowable stress of the steel is used in the calculation, and a sufficient safety factor is ensured. Generally, the ratio between the maximum deflection and the span is 1/250 ~ 1/150.
