钢筋混凝土空间网格结构包括平板型的空腹网架结构、空腹夹层板结构、空腹双重网格结构、现浇混凝土空心大板楼盖结构。这些新型结构体系从20世纪80年代至今在跨度18～32 m公共建筑的屋盖和楼盖应用达100多万平方米，取得很好的社会与经济效益。有的已编制了相应的技术规程。我们研制了将钢筋混凝土空腹夹层板单向弯曲形成的钢筋混凝土空腹夹层网壳和网拱结构，双向弯曲形成的钢筋混凝土空腹夹层双曲扁网壳结构。这些拥有我国自主知识产权的空间网格结构新体系，均具有自身的特点和对建筑物的适应性，文章将按研制时间先后逐一介绍。其结构的“安全、合理、经济、先进”性，则通过工程实例予以剖析。

Reinforced concrete spatial grid structure includes planar open-web grid structure, open-web sandwich plate structure, open-web dual grid structure, cast-in-place concrete round eye hollow plate structure, these new structure systems have been applied in the plate of public buildings amount to more than 1 million square meters from the 1980s until now, and obtained the excellent social and economic efficiency. The corresponding technical specifications for some have been established. In recent years, we have developed the reinforced concrete open-web sandwich shell and arch structure through bending the reinforced concrete open-web sandwich plate structure by one direction,and the reinforced concrete open-web sandwich hyperbolic flat shell structure through bending the reinforced concrete open-web sandwich plate structure by the two directions These new spatial grid structure systems have the proprietary intellectual property rights of our country and have their own characteristic and the compatibility for the buildings. In the paper, we will introduce one by one successively according to the development time order. The security and rationality and efficiency and advancement of the structure will be analyzed through the project examples.
