Pile foundations are among the most widely used deep foundations. Compared to the full-area foundation, here the weight of foundation and extent of excavation works have been reduced while the sheeting and massive backfilling have been eliminated. Concrete piles have been usually made of plain concrete or reinforced concrete. Piles of circular, square or polygonal shapes have been mostly used. Their dimensions differ depending on the technology used. The paper presents effects of piles loaded by bending moment. The solution depends on the chosen model of a pile, of subsoil, and the interaction between them. The piles loaded in bending have been mostly investigated as elastic rods, which act together with elastic and homogeneous subsoil or a pile-lengthwise variable subsoil of Winkler type with bilateral bonds between the pile and the subsoil. Winkler subsoil model describes the behaviour of incoherent subsoil properly enough. Presently, in addition to the deterministic approach, also some new approaches are being used in the design and assessment of building structures. The probabilistic analysis represents one such approach. Input values have been entered as stochastic ones and they have been characterized by various distributions (Gaussian, lognormal, etc.). Values of input variables have been generated either randomly (using Monte Carlo simulations), or using the Response Surface Method (RSM). Selected results of the performed analyses have been presented in the conclusion.
