In this paper, results obtained in both conventional and finite element analysis of straight and belled anchor shafts subjected to a pullout force are presented. In numerical analysis, it is assumed that no drainage takes place during the anchor pullout. Comparisons between two conventional methods of analysis for ultimate pullout load and the results obtained by the finite element analysis are also presented. The load-deformation and stress-strain responses in the shaft, in the interface between shaft and soil, as well as in the soil are discussed.
