| 摘 要： | 分析了应急装配式钢桥安全性因素,建立了基于设计、制造和使用因素的钢桥安全性评估模型（AHP模型）,进而提出了结构基频、挠度等10个评估指标的具体评分方法,然后利用关键构件裂纹长度修改系数来评估钢桥的安全等级。实例应用表明,该评估方法可用于100型、＂321＂型和200型钢桥的安全性评估。

| Abstract: | Upon the basis of analyzing the safety factors of portable steel bridges,an Analytic-Hierarchy-Process-based(AHP)safety-assessing model for portable steel bridges is established in the paper,with all the design,manufacturing and application factors taken into account,after which the specific rating methods for ten indexes,such as the first natural frequency,deflection,stress,etc.of the structure,are further put forward.Finally,the crack-length-based modification coefficients for the key members are used to ... |
