Resumo

The basic concepts of an applied technique of finite-element inelastic analysis are presented for the connections of intersecting shells. The determination of the limit load as a parameter that assigns the bearing capacity to a structure is also presented. The results of computations with the developed program SAIS are compared to the experimental results obtained by testing a cylindrical vessel model with a nonradial branch pipe. The dependencies for the nonradial connections are provided, which show a significant decrease in the limit load when the branch pipe is inclined from the radial position. The results of the parametric analysis are given, which demonstrate the effect of the inclination angle of the branch pipe and the diameter ratio of the branch pipe and vessel on the value of the limit load.
