In this paper, the principles of constitution and the engineering application of the cable-stayed space grids are described, a model test is made. By a lot of examples calculated with the program of non-linear analvsis of cable-stayed space grids, the calculated model and the-static structural behavior of this sfructural system with different arrangement of cables, different shape and stiffness of the tower, different stiffness of the cables are studied.
    This paper also introduces the design and construction of the cable-stayed space grids con-structed at the sports ground of Zhejiang University, and some reference opinions on engineering design are recommended.
Keywords: cable-stayed space grids; structural characteristics; hybrid structure
