Tension detection of suspension rods in steel-concrete tied arch bridges and analysis of the impact of suspension rod failure
In order to analyze the impact of cable force changes on steel reinforced concrete tied arch bridges,based on historical cable force detection data,the variation of cable force deviation during bridge operation was analyzed.Based on the engineering records of bridge replacement of suspension rods,the impact of different suspension rod failure conditions on the response parameters of bridge structures was discussed.The results indicate that in the daily maintenance of steel-concrete tied arch bridges,special attention should be paid to chan-ges in cable tension and bridge deck alignment.When the suspension rod fails,timely replacement work should be carried out to avoid safety accidents.
