Parametric design and mechanical performance analysis of hyperbolic flat reticulated shells

摘要

A parametric design macro program of five kinds of hyperbolic flat lattice shells was developed by using APDL (Ansys Parametric Design Language) parametric design language. On this basis, hundreds kinds of working conditions of three kinds of hyperbolic flat lattice shells were selected for the change of long and short span of vector high, and did the structural force performance comparison analysis. In these three types of hyperbolic flat latticed shells, the three-dimensional lattice-type reticulated shell has the most reasonable mechanical properties, with long span of the ratio of vector high to span fa/a= 1/3 and short span of the ratio of vector high to span fb/b=1/6 are suitable. those provides a reference for practical engineering design.
