Grid-purlin system composed of RHS members are known to be effective to prevent buckling of the welded beams. In this paper, lattice dome composed of radial beams and welded grid purlins (Grid purlin shell dome) are studied. The linear, elastic, and elasto-plastic buckling strength of Grid purlin shell domes are analyzed using detailed FEM analyses. Their results are compared with the shell theory with continuum analogy and easy design approaches are investigated.
