JUSTIFICATION OF EXPLOITATION TANK WITH GEOMETRICAL IMPERFECTIONS FORM WALL
On the basis of data surveying wall RVS-20000 authors developed a finite element model of the tank, which takes into account the actual geometry of the building with a view of the wall of geometric shapes of deviations from the ideal cylindrical shell. Tank’s design scheme for the analysis of stress-strain state of the tank wall at the existing design of operational loads. It was found that the SST calculation of vessel taking into account the imperfections of geometric shapes give smaller values of safety margin, than the calculation of the ideal shell. Results for reliable determination of SST of the concrete tank with imperfections geometric shape when the current operational loads, it is necessary to develop a model that reflects its real geometry in accordance with the coordinates of the points of the wall surface, which can be obtained as in the traditional theodolite and modern 3D laser scanning methods.
