000012202 520__ $$2eng$$aThe gradation index of safety and reliability evaluation of in-service concrete girder bridge members is discussed based on the reliability theory and the existing safety evaluation methods. Modifying the reduction rate of loading capacity used in Code for Maintenance of Highway Bridges and Culvers, a new reliable index is presented in the same safety standard to reflect the relation between load and resistance. According to the basic principal of calibration method, a procedure is programmed with Matlab language to compute the recommended gradation index under various factors such as different load combinations, vehicle operating status and different failure modes. With these calculated numerical values, the calculated reliability indexes standard for the estimation of safety degree of in-service concrete girder bridge members is ultimately obtained.
