- Abstract:
- A comprehensive evaluation method of bearing capacity was proposed for highway T beam bridge based on fuzzy stochastic theory.Factor indexes of load bearing capability were produced by stochastic simulation according to on-site test data.Then the probability distribution of the bearing capacity partial check coefficients and the load bearing capacity were obtained by fuzzy comprehensive evaluation theory.Finally the load bearing capacity with certain guarantee rate was figured out.An example of reinforced concrete (RC) T type beam bridge was analyzed and the feasibility of the proposed method was demonstrated.The results provided reference for highway bridge bearing capacity evaluation and repair management.
