Test and analysis of the main crane girder stress and the dynamic characteristics of column

摘要

Due to the long construction time of a steel mill, carried on reinforced many times, multiple replacement and an increase in crane, the pillars of the main building now have a larger vibration. Roof damage Serious. Plant leak serious, in order to guarantee the reliability of building structure, needed to carry out the reliability evaluation of the plant, in this paper, the stress and dynamic characteristics of crane beam and column are tested. In order to evaluate the crane beam system better and the column system for more comprehensive, provided reliable basis for strengthening and rebuilding of plant.
