Abstract

Hexagonal grid cylindrical latticed shell structure is proposed, due to honeycomb structure (although the hexagon structure) is the most effective structure on save the building materials. As a result of the shell structure always with numerous bars, the distribution of internal force and the design of bars often rely on many parameters, likes the span of the structure, the rise-span ratio of the structure, the size of mesh etc., the large scaled finite element software ANSYS parametric design language ANSYS Parametric Design Language (APDL) be used to establish the model of hexagonal grid single-layer cylindrical reticulated shell. The optimization design also was done to found whether the model was a feasibility one. The analysis process shows that the parametric design method provides great convenience for the design of the structure.
