This is a structural design proposal of cylindrical shells with interconnected CLTs. To construct the shells with discrete panels, the joints must have axial, in-plane/out-of-plane shear and out-of-plane bending stiffness. For ease of construction, easy-to-handle connectors should be used for joints. In a previous report, the authors proposed an out-of-plane bending joint by using LSBs. In this paper, loading tests of the joints are conducted to confirm the out-of-plane bending properties. In addition, a case study in which CLT shells composed of joints considering stiffness in each direction, including the joints, is adopted to an actual building is presented.
