In this paper, the ultimate load of the cone piece of steel space frame is analyzed by using the struc-tural plastic limit analysis theory. The formulas to calculate ultimate load and size of the cone piece are obtained. The formulas can be consulted when the cone piece of space frame is designed.
Keywords: space  grid; cone  Piece; analysis; ultimate  bearing  capacity; design
