Abstract

Taking the Jinan National Games Stadium as an example, according to the characteristics of the hoop-shaped spherical reticulated shell, the APDL language (Ansys Parametric Design Language) was used to program the parametric macro design of the single-layer reticulated shell, and the ANSYS software was used. This structure (different spans S1, S2, different top opening diameters d, different vector heights f, different numbers of circumferential area parts kn, different radial node turns Nx) was subjected to force analysis. The results show that the application of the parameterized design macro program can facilitate the modeling design and performance comparison of the reticulated shells, which provides great convenience for the reticulated shell structure design. According to the analysis of 4 groups of 21 examples, the structural performance is better when the span S1 is 100 meters, the opening diameter is d=60 meters and the vector height is f=30 meters (vector span ratio f/S2=1/3). For this kind of reticulated shell structure optimization design and engineering application provides a useful reference.
