While the possibility of large space structural systems is pursued, it is important to study a new structural system as well as a new performance of materials. One of possible structural systems that have been developed is the hybrid system combining a space frame structure with a cladding, for example, a concrete slab, steel panels or membrane. In this case, constituent members of the structure are subjected to laterally distributed load due to the dead and live load. Then in this paper, the elastic buckling behavior of latticed structures is theoretically investigated on the condition that constituent members are subjected to laterally distributed load by using the proposed tangent stiffness equations of beam-column members. The treated latticed structures are double-layer latticed grids, cylindrical latticed shells and single-layer latticed domes.
