In order to grasp the structural behaviors of a new type of single-layer lattice shell consisted of aluminum members and joints, the following researches had been planed and performed : (1) Experiment of structural elements such as member and joint, (2) Experiment of small-scale models. These results were presented in the reference [1]. In this paper, analytical researches on the structural behaviors of the single-layer lattice shell consist of aluminum members and joints are performed. This single-layer lattice shell has the insertion joint system which has a varied type of an edge shape of tubes and an uneven shape of insertion joint with a hab and fillers. In the first part, analytical studies, using the finite elememt method, on the structural behaviors of the edge shapes of tubes and the uneven shapes of the insertion joint in the hab are shown. In the second part, using this analytical results, the analytical model of the tube with the insertion joint are presented. In the last part, non-linear analyses of the three kinds of small-scale models with a diameter of 4.2 meters which were examined in the reference [1] are performed.
