Prediction and analysis of deterioration of Moscow Bridges

摘要

Adequate description of deterioration of structures and their elements is veryrnimportant for the effective use of the BMS. In the course of exploitation of Moscow BMS,rndeterioration processes have been studied using the results of standard inspections of 1,059rnfacilities. The analysis shows that for structural SE, deterioration of strength properties virtuallyrndoes not occur or is of accidental character. In most cases, deterioration is attributable primarilyrnto the wear of materials, which depends to a large degree on the quality of their manufacturingrnand protection. Also, lifespan prediction for a set of SE should take into account their mutualrneffects on each other. The methodological sequence of adjustment of deterioration models forrndifferent SE, initially adopted on the basis of experts' judgments, is suggested.
