| According to the analogue principle, this paper set up the analogous models in statics and kinetics of reinforced concrete T beam and bridge. By loading step by step ,the static and dynamic examinations have been done alternately with the models at different damage stages. From the trial of single T beam, an empirical formula was established to express the relations of parameters a and fJ. To analyze the orthotropic bridge with many cross diaphragms, this paper adopted the finite strip method of orthotropic assimilate plate, based on which the dynamic decomposed method was set up and the static stitThess of each single beam could be forecasted form dynamic parameters. The experiment and analysis showed that there was little difference between the forecasted value and the real. The method of evaluating the capability of bridge structure was given at the end of the paper. This paper researched the application of dynamic method in evaluating bridge capability, and we hope it can be referenced to the new Criterion. |
