In designing a roof of a large span structure, such as a roof of a gymnasium, double-layer space latticed structures are widely used. The double-layer space latticed structures are applied by a cylinder, a dome or a curved surface, the curvature of which can be changed freely, etc. The meshes are classified by a triangle, a square, a hexagon or a combination of them in the two layers. The structural characteristics of double-layer space latticed structures will be changed greatly according to the forms and mesh patterns. In this paper, the elastic buckling behavior of double-layer space latticed structures affected by the effect of forms and mesh patterns is investigated by analyzing many kinds of double-layer space latticed structures which are combined with often used mesh patterns and forms. The treated mesh patterns are "square + square" , "square + diagonal" , and "diagonal + square". The forms treated are plates, domes, cylinders and translation shells.
