REDUCTION OF RIGID ROLLED U-SHAPED ARCH PROFILETO A PROFILE WITH T-SECTION

Assessment of the reduction rigid rolled U-shaped arch profiles features finds difficulties first of all in their geometrical form and functioning. In this article there was made a calculation of reduction of rigid rolled U-shaped arch. While taking into account the complication of their assessment, two main calculating methods were considered. The first one is experimental, while the other is solid models modeling, taking into account the rolling of the profiles. Within the scope of this work the second method of reduction rigid rolled U-shaped arch profiles features assessment was examined. In this case the calculation of the reduction rolled profiles proceed along their length with the conversion their form to an T-shaped section. The profile modeling was based on the Solid Works software package. The results are the estimation of reduction rigid rolled U-shaped arch profiles features as well as the substantiation of the T-shaped section conversion.
