摘要：

为了确定网架结构因钢材遭受大气腐蚀而引起的结构性能退化,用钢材长期暴露腐蚀试验所得的模型代替实际腐蚀过程,建立以杆件应力为主要症状的结构可靠度方法.在杆件壁厚随时间不断改变的条件下,将控制杆件的应力随时间变化曲线用于拟合Weibull模型曲线,以此生命症状模型对网架结构进行基于症状的可靠度分析和结构剩余寿命预测.考虑实际健康监测所得症状值与理论预测值的差异,对可靠度分析结果进行修正.算例结果表明,在单一损伤所致性能退化条件下,结构可靠度和结构剩余寿命以设计年限为基准,逐年递减.该结论与相关文献的结果一致.
Abstract:

In order to determine the performance deterioration of latticed structures subjected to steel corrosion under atmospheric exposure, symptom-based reliability method employing stress evolutions of structural members as a primary symptom was presented, where the practical steel corroding process was replaced by the model gained from long term experimental results of steel exposed in corrosive environment. The Weibull model curve, fitted by the stress-time curve of the controlling member with its wall thickness decreasing constantly, was employed for symptom-based reliability analysis and lifetime prediction of latticed structures. Considering the discrepancy between symptom data from the practical health monitoring and those from the analytical results, the predictions of symptom-based reliability analysis were updated. The results from a case study show that the structural reliability and remaining useful lifetime drcrease year by year, based on the design reference under the consideration of the performance deterioration due to the single cause for damage. This conclusion grees with those published in previous papers.
