Parametric Design of Six Typical Semi-Outdoor Reticulated Domes

According to the rules of six typical spherical reticulated shell nodes, the modeling method and the design macro program is developed for the nodes and the bars of six typical semi-outdoor spherical reticulated shell structures by using the ANSYS parametric design language APDL, so as to achieve the parametric design of six typical semi-outdoor spherical reticulated shells. The modeling design examples indicate that it's convenient to achieve the parametric modeling and design of semi-outdoor shell with given span S, rise high F, number of hoop symmetry areas kn, radial node cycles of whole structure nx and the upper removed laps ns, which provides big convenience for the force analysis and the optimization scheme comparison of semi-outdoor spherical lattice shells with varied types and geometric parameters.
