Abstract
Based on the structure features of double reticulated domes, a method for node generation and element connection of six typical double reticulated domes was produced. A macro program was designed by using ANSYS Parametric Design Language (APDL). The six typical double reticulated dome modeling was produced under given parameters such as span, rise high, double 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.
