Parametric Modeling of Six Typical Double Primary Ribs Reticulated Dome

Based on the structure features of double primary ribs reticulated domes, a method for node generation and element connection of six typical double primary ribs reticulated domes was produced in spherical coordinate system. A macro program was designed by using ANSYS Parametric Design Language (APDL). This six typical double primary ribs reticulated dome modeling was realized under given parameters such as span, rise high, double primary ribs thickness, grid number in circular and radial direction. It is proved by several examples that this method is simple, efficient and possible. It can be easily used to analyze the internal force and optimized design in shell structures.
