Most of the short span suspension bridges with steel truss girders early constructed will approach their design service life. Correctly evaluating the actual service performance is the basic basis of repairing, strengthening and technical reconstruction. First, load-bearing capacity evaluation based on static load test was briefly introduced. Then, combined with Chengnan bridge, the main existing damages and their causations of the bridge were summarized and analyzed. Based on the field detection datum and original design load grade, the finite element mode with some damages was established. Then, by analyzing the calculation results, the scheme of static load test was confirmed. Through comparing the static load test results with the results of upgraded finite element, the actual conditions of the existing bridge structure were evaluated. In order to resume its load-bearing capacity, some of measurements and suggestions of strengthening were proposed.

Technical Basis

In order to evaluate the stress and working performance of a reinforced concrete box-ribbed arch bridge after completion, the load test of the bridge is carried out. Static load test is to test the stress and displacement of each section of arch rib under the action of partial load and medium load. Through the experiment with the key parts of the stress (strain) and displacement load and other important data, through analysis and study, the comprehensive analysis of the phenomenon of calculation and test, a comprehensive performance evaluation structure and function whether meet the design requirements, to provide technical basis for the safety of the bridge operation, and provide the original material for the bridge maintenance and management in the future.
