This paper summarizes the results of numerical studies into the effects of initial geometric imperfections on the elastic buckling behaviour of steel circular and elliptic toroidal shells subjected to follower-type external pressure. The types of initial imperfection studied are (a) axisymmetric localized ones and (b) sinusoidal buckling modes. The principal localized imperfections studied are (i) circular increased-radius "flat spots" and (ii) smooth dimples. The buckling pressures pcr of circular toroidal shells were not very sensitive to initial imperfections. With elliptic toroids, whether the shell was sensitive to initial imperfections or not depended on the ratio k(≡ a/b) of major to minor radii of the section. The shells on the ascending part of the pcr versus k curve behaved like circular toroidal shells, i.e. they were not sensitive to initial imperfections. However, the behaviour of elliptic toroids on the descending part of the versus k curve was very different. The numerical results quoted in the paper are for limited ranges of the geometric parameters. It would be useful to extend these ranges, to explore the effects of plasticity and to conduct model tests on imperfect steel models to verify the conclusions of the numerical studies.

Vinnytsia National Technical University The estimated cost of construction of foundations reaches about 40% of the total estimated cost of the building. In the industrial and civil construction of Ukraine due to its geological conditions it is advisable to use pyramidal piles and the peculiarities of their interaction with the foundations and theoretical calculation methods are insufficiently studied. The lack of reliable methods for estimating the bearing capacity of pyramidal piles leads to an increase in inventory ratios and imperfect decisions. Therefore, the topic of VAT research of rational pyramidal piles is relevant. Numerical studies on the IHE to determine the VAT and bearing capacity of pyramidal piles, which are characterized by load resistance with equal subsidence. Numerical studies of the pyramidal pile were performed on the numerical IHE. MGE - a modern numerical method for solving boundary value problems of structural mechanics, has attracted the attention of researchers mainly by the fact that the continuous environment is divided into a number of elements that can be considered as separate parts The analysis of results of numerical researches is carried out, the correlation with experimental data which are restrained by direct measurement of pressure in a soil basis by mezdoses is carried out.
