Abstract
Computer studies of natural vibrations of reinforced concrete structures of caisson type in two software complexes - SolidWorks and ANSYS. Parametric models are constructed. Calculations were carried out for six thickness ratios of the plate and the rib height. In each variant, five frequencies are defined. The results of solving the problem in ANSYS invariants with respect to reducing the size of the finite element grid, while the results of calculation in SolidWorks essentially depend on these dimensions. The spectrum of natural frequencies in SolidWorks in all cases is overestimated in relation to the calculation in ANSYS - up to 22.7 % at the lowest frequency of oscillations. It is concluded that for the dynamic calculation of coffered ceilings, the use of the SolidWorks software package is inappropriate.
