    Abstract:

    Taking the Changzhou Stadium-Kiewitt lamella ellipsoid parabolic shell as an example, two types of 6 kinds of hybrid ellipsoidal paraboloid reticulated shell parameterized design macro program are developed by using the APDL(Ansys Parametric Design Language)parameterized design language. ANSYS software is used to compare and analyze the force performance of 6 kinds of reticulated shells. The results show that:Under the same condition, the structure and mechanical properties of Kewitte-lamella ellipsoid parabolic shell is the most reasonable. Therefore, it's a priority selection in practical engineering. The vector span f/S of the first type hybrid elliptic paraboloid reticulated shell is 1/4~1/3 and the optimal force performance of second kinds of reticulated shells with sagittal span ratio f/S to 1/3~1/2 is optimal. This paper provides a certain reference for the shape optimization and engineering design of this kind of reticulated shell.
