针对目前规范中尚未明确斜拉桥结构的校验系数常值范围,提出斜拉桥结构状态评价应基于主梁、拉索、主塔3部分构件的校验系数进行;利用统计软件Minitab对各构件的校验系数样本进行分析计算,最后确定了斜拉桥结构的主梁构件、拉索构件及主塔构件各自校验系数的取值范围。研究结果表明:斜拉桥主梁构件的应变校验系数在0.60～1.00是合理取值范围,挠度校验系数在0.72～1.00是合理取值范围;拉索构件的索力校验系数在0.76～1.00是合理取值范围;主塔构件的应变校验系数在0.18～1.00是合理取值范围,偏位校验系数在0.47～1.00是合理取值范围。
Aiming at the range of constant value of the calibration coefficient of cable-stayed bridge not yet specified in current codes, the structural state evaluation of cable-stayed bridge is proposed based on the calibration coefficients of three components of main girder, cable and main tower. Using the statistical software Minitab, Component of the calibration coefficient sample analysis and calculation, and finally determine the cable-stayed bridge structure of the main beam components, cable components and the main tower components of the calibration factor range of values. The results show that: the strain of the main girder component of cable-stayed bridge calibration coefficient in the range of 0.60 to 1.00 is reasonable, the deflection coefficient of calibration in the range of 0.72 to 1.00 is a reasonable value; cable component of the cable force calibration coefficient of 0.76 ~ 1.00 is a reasonable range of values; the strain correction coefficient of the main tower component is within a reasonable range of values from 0.18 to 1.00, and the calibration coefficient of deviation from 0.47 to 1.00 is a reasonable range of values.
