| Summary |
Membrane structures and tent warehouses are commonly framed with a steel pipe truss structure.In the structural calculation of these structures, the frame model composed of linear elements converted from the truss structure is generally used.Section forces obtained by frame model is converted to the axial force of truss members, and safety is verified.On the other hand, actual steel pipe truss structures may have the eccentricity of lattice members or distributed forces on chord members.In this study, through the comparison and analysis of displacement and stress, a structural design method used frame models is proposed.
