Abstract Cable-stayed spatial grid structure, composed of pylons, inclined cables and spatial grid structure, is one kind of rigid-flexible-mixed-structures which has being used widely. This paper elaborates the mixed-structure’s development in china systematically. Firstly, the structural configuration development and part engineering applications are introduced. Then, it focus on reviewing the studies on the structural specialties of cable-stayed flat-plate grid structures and cable-stayed reticulated shell structures, and also analyzing the dynamic characteristics of the cable-stayed reticulated shell structures from aspects of structural geometrical nonlinearity，parametric vibration of the cable and mode jumping. Based on the former researches, remaining issues and prospects for the mixed-structure’s developments are put forward at the end of this paper.
