Review article

The current research is focused on the study of the distribution of tensile forces acting on reinforced concrete large-size modules during transportation in factory conditions as well as during installation on the construction site. The determination of the appropriate position of the center of the module mass is carried out. It is necessary to further accumulate statistical data on the magnitudes of the forces acting on the reinforced concrete large-size modules in order to study the influence of volume-planning and structural solutions of reinforced concrete modules on the distribution of forces at the slinging nodes. Determination of the most disadvantageous combination of forces will allow specifying the boundary conditions in the design as well as optimizing the design of lifting elements and reducing their material intensity. The forces at the module slinging points are determined for a reinforced concrete large-size module as follows: by calculation, with the help of the weight measuring system of the portal conveyor and dynamometers during lifting of the module by the crawler crane. The position of the module mass center corresponding to the obtained forces is determined. Deviations of the module mass center from the geometric center of the module in the longitudinal and transverse directions of the module are obtained.
