【 摘 要 】

The article presents the analysis of the influence of the rebars distribution, in reinforced concrete beam section, on the perpendicular (to the side surface) deformation of the tested element. The beams were tested under the load of two forces. Displacements and crack formation in middle part of reinforced concrete beams were measured by using 3D optical scanner. Test results confirm the large influence of the asymmetry of the reinforcing bars distribution, within beams cross-sections, on their deformation and crack formation during loading. It is shown that the displacements perpendicular to the side surface are consequent upon irregularities in the distribution of the main reinforcement due to errors in the stage of beams manufacturing in the precast factory.
