Analysis of the Influence of the Deviation of Suspension Cable Force on the Mechanical Performance of the Arch Ribs of Multi ribbed Steel Box Tied Arch Bridges
In order to meet the growth of traffic volume and ensure the aesthetic appearance of bridges,more and more multi ribbed steel box tied arch bridges have emerged in urban bridges.In order to study the effect of cable force deviation of suspension rods on the mechanical performance of the arch ribs of a multi ribbed steel box tied arch bridge,a multi ribbed steel box tied arch bridge was selected as the re-search object.Numerical analysis methods were used to study the effect of cable force deviation of suspension rods on the internal force and stress of the arch ribs of the multi ribbed steel box tied arch bridge.The results show that the influence of the deviation of the cable force of the middle arch rib suspension rod on the internal force and stress of the arch rib is significantly greater than that of the deviation of the ca-ble force of the side arch rib suspension rod on the internal force and stress of the arch rib.This indicates that for multi ribbed steel box tied arch bridges,special attention should be paid to the influence of changes in the cable force of the suspension rod of the middle arch rib on the mechanical performance of the bridge arch rib.
