Abstract: According to the reliability evaluation of the structure of a heavy industrial plant which was near service limit years, several major safety hazard issues were found and corrective measures to reinforce were proposed. On the basis of structural calculation and analysis, whether to upgrade the crane can be determined and the upgrade feasibility projects were proposed, which can provide the basis for other similar identification.
Keywords: reliability assessment; steel structure; crane upgrading; structural calculation and analysis
