| Popis: |
At the time of reconstruction of edifice, it often appears a need in researches of bearing capacity for prefabricated reinforced concrete crane beams for the purpose of their exploitation in future. And also the designers look into possibility of installation modern bridge cranes with technical characteristics, which are different from foreseen or existing bridge cranes for establishment on these constructions. Different mark of cranes by equal weight-bearing capacity during the exploitation cause appearance of bending moments and shear in reinforced concrete crane beams, the values of which differ depending on technical characteristics of cranes. The maximum load of the wheel on the crane and the distance between the wheel’s axes are important characteristics of hoisting cranes during researches of bearing capacity for prefabricated reinforced concrete crane beams. Accordingly, the exploitation of reinforced concrete crane beams is possible only after research of bearing capacity for these constructions by means of plotting of bending moment diagram and shear diagram, and moreover analysis of changing for deflected mode of these constructions. |
