PROBABILISTIC ANALYSIS ON THE LOAD UPON THE EXISTING BRIDGE STRUCTURES
In this paper, the probability particularity of loads on the existing bridge structures are analyzed and calculating method on statistical parameter are put forward, in allusion to the particularity of loads on the existing bridge structures. The evidences to analyze the existing bridge structures loads for the assessment of existing bridge structures are provided. The distribution of the existing bridge structures loading effect is analyzed. The vehicles loading effect is simulated, and based on the idea which is pointed out that the distribution of vehicles loading effect belongs to extreme value I distribution. The existing bridge load base period and the range of the load are analyzed. The stationary binomial process model is used to predict the existing bridge loads. The groundwork of reliability analysis and identification of existing bridge loads is laid through the study work mentioned above.
