Abstract
Recently various kinds of free-formed single-layer latticed shell structures with glass surface are realized in Europe for covering public open spaces. The connection system for such structure requires out-of-plane strength and stiffness, and the buckling stability of such structures is affected by the stiffness of the connections. In this report, simple connection system composed of hollow-cylindrical nodes and tension bolts is proposed. The stiffness and strength of proposed connections against out-of-plane bending, in-plane bending, compression, and tension forces are confirmed by experiments, and the effects on the buckling strength of sample structure are discussed.
