In this paper, the load-bearing capacity and the buckling behavior for the hybrid system that combines a latticed structure with metallic sheets are theoretically made clear, and results of the hybrid system are compared with a separate sub framing system. In comparing the hybrid system that combines a latticed frame and sheets with a separate sub framing system, the initial stiffness of the hybrid system is generally higher than that of a separate sub framing system. The maximum load of the hybrid system is bigger than that of a separate sub framing system. The composite effect for the maximum load of the single layer latticed dome is bigger than that of the single layer cylindrical roof shell. For the single layer latticed dome, the maximum load divided by the weight of a latticed frame and sheets of the hybrid system is bigger than that of a separate sub framing system. However, for the single layer cylindrical roof shell, the maximum load divided by the weight of a latticed frame and sheets of the hybrid system is smaller than that of a separate sub framing system. Therefore, the single layer latticed dome is more effective structure for the hybrid system than the single layer cylindrical roof shell.
