Lattice shells have various forms, mesh patterns of member arrangement and boundary conditions. The buckling behavior is different depending on these parameters. As considered, reliability indexes for lattice shells under vertical loads are determined by these parameters. Therefore, it is important to accumulate the results with reliability analyses for various lattice shells. In this study, reliability analyses are performed for the cylindrical lattice shell roofs under dead load and uniform snow load using member slenderness ratios, boundary conditions and half open angles as parameters. The relationships between load factors for snow depth of 0.5 m and reliability indexes are clarified.
