The present paper discusses not only a linear buckling axial force but also an elasto-plastic buckling axial force for cylindrical latticed shells composed of diagonal and horizontal members. The cylindrical latticed shells are assumed under axial compression, which yields large axial forces to horizontal members. The discussion focuses mainly on the buckling behavior of horizontal members. First, the linear buckling force is derived using continuum analogy and the parameters affecting to the buckling behavior are analyzed. The analysis has shown that the subtended half angle of the members and the member slenderness dominantly affect to the linear buckling force. Second, the elasto-plastic buckling force for the horizontal members is expressed in terms of generalized slenderness which includes the buckling characteristics as continuum shell.
