摘　　要：不锈钢具有耐久、耐腐蚀、耐火、耐低温、造型美观、维护费用低等优点,在空间领域得到越来越广泛的应用。目前国内对不锈钢基本力学性能的研究还较少,相应的不锈钢设计规范还在编制中。在介绍不锈钢材料的特点和分类基础上,总结了当前国内外对不锈钢的材料力学性能、轴心受力构件力学性能研究现状。对不锈钢焊接空心球节点的焊接性能、节点承载力以及不锈钢螺栓球节点的相关研究成果进行总结,对不锈钢在空间结构中的工程应用进行重点总结。最后对天津大学不锈钢四面体张拉整体结构的力学性能进行分析,并对不锈钢在空间网格结构的应用研究前景进行展望。Stainless steel enjoys better popularity in spatial structure construction for its endurance, anti corrosion, fire resistance, low temperature resistance, its attractive appearance and the low cost for repair. Recent researches on mechanical property of stainless steel are still limited and the relevant standard is under composition. Under the basic introduction of its material characteristics and classification, this paper summarized the research status about the mechanical property of the material and the uniaxial bearing members at home and abroad. The paper summarized the welding performance and the node bearing capacity of stainless steel welded hollow spherical joints as well as the relevant research findings of the stainless steel bolted spherical joint, especially the engineering application in spatial structure. The mechanical property of tetrahedron tensegrity structure made of stainless steel in Tianjin University is analyzed at the end of this article. Its promising future in space grid structure application is referred as well.
