The present investigation deals with the effects of initial imperfections on the ultimate strength of a single layered reticular dome whose connections are semi-rigidly jointed. The initial imperfections are an initial deflection and an additional concentrated load at the single nodal point of the dome. Elastic and elasto-plastic buckling analyses are executed with respect to several parameters which define the magnitudes of imperfections. These results from the calculations are summerized by a classical buckling load of isotropic shell which is equivalent to the framed dome. From the results some conclusions about the effects of adoped imperfections are drawn.
