Advances in Research and Application of Steel Spatial Structures

The advances in research and application of steel spatial structures in recent years are reviewed in this paper. The reasons for the con-tinuous development of steel spatial structures and their classification are discussed first. On the key research topics,research findings in structural analysis and design theory,stability of lattice shells,seismic behavior of space frames,and wind vibration problems of tension structures are set forth in particular. Problems that need further research are also presented. In engineering application, typical engineer-ing projects of steel spatial structures are taken as examples to illustrate the special features of recent development. These features are summarized as: the variety of forms, rational application of pre-tensioning, and being combined with membrane structures. Views on the trend of future development of steel spatial structures are presented as the conclusion.
