摘要:
针对中小跨径T形粱桥的特点,提出了一种模糊随机的上部结构承载能力综合评估方法.根据现场检测结果对承载能力评定的各因素指标进行随机模拟,应用模糊综合评定方法得到各分项验算系数和承载能力的概率分布,进而计算得到具有一定保证率的承载能力评定结果.通过对某公路钢筋混凝土简支T梁桥的计算,验证了该方法的可行性,且研究结果可为公路桥梁的承载力评定和维修管理提供参考.
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.
