| Abstract: | Production run of metallurgical industry characters frequent operations in crane girder system and results in fatigue damage as a signal of premature fracture over there. To analyze crane girder performance under actual situation in service along with necessary measurement in situ, method estimating residual life has been deduced based on cumulative damage rule. |
