The loading coefficients are calculated for real models of Venus taking into account the asthenosphere for anomalous density waves positioned at different characteristic levels. An associated analysis of the topography and the non-equilibrium part of the gravitational field allows one to determine long-wave primary tangential stresses in the lithosphere and mantle for zonal harmonics with n = 2-8. The stresses in the lithosphere of Venus are approximately equal to 30 bar, while those in the lower mantle can be up to 45 bar, but they are only on the order of a few bars in the weakened upper mantle. The low level of tangential stresses in the core and mantle of Venus is an important indication that the interior of the planet is intensely heated. A conclusion is drawn on aseismic nature of Venus.
