| Abstract: | Octahedral steel casting joints are used in the large-span structure of National Stadium in Beijing to transfer the inner columns from the diamond section into the rectangular section. It is introduced that geometric configuration of the polyhedral joints, the measure to reduce the stress concentration, the finite element method analysis and strength criterion, the material specification of the steel castings, industrial flow, manufacture techniques as well as quality control. |
