| Bridge load test high reliability,and other characteristics for its targeted as the primary method Bridge performance evaluation and widely used,and calibration coefficients as an important indicator of performance evaluation,its value objectivity and reliability of the bridge structural performance evaluation of objectivity have a significant impact.This evaluation is a certain way of limitation,is not comprehensive enough,without considering Found quantitative factors should be considered in conjunction resistance index.Structure itself has a certain safety margin for the structural design of the high safety margin structure,an important indicator of performance evaluation as a structure,requiring calibration factor is not so harsh.Calibration coefficient value evaluation of the reliability,but also an important indicator to consider is the relative residual,there is no direct relationship between relative residue and calibration coefficients,but from the relative residual value index considerations for measured values smaller the structure,the relative residual is significantly larger,calibration coefficients may be distorted,causing the bridge structure and properties of miscarriage of justice.Limitations of calibration coefficients of this evaluation,the paper will be based for the bridge carrying capacity Load Test Evaluation based on calibration coefficients increase arch static performance evaluation objectivity,the first based on the detection of the state of technology assessment and Structure Calculation both inadequate bearing capacity of the existing bridge assessment methods were discussed,then arch stress calibration coefficients basic assessment unit for analysis and selection of calibration coefficients represent the value of the study,based on the establishment of the final calibration coefficients and structure calculation comprehensive evaluation indicators to structure a more reliable evaluation. |
