The last decades have seen major advances in the research. Design and construction of steel (pace structures space grid structures) in China. This paper provides a review of these developments. With partieular attcntion to the new technologies and new structural forms employed in China. The fllowing topics on new technologyies and new structures are given emphasis; long-span and large-arca grid structures. Composite space trusses; composite reticulated shells; triple-layer space trusses; partial double-layer (single-layer) lattice shells: prestressed grid structures. Cable-stayed grid structures: special trid structures: new types of joints; theoretical work and application research. Prospects for steel space structures in thd 21st century are presentel at thd end of this paper.
