%X 轻钢结构是天然的绿色建筑，也是天然的工业化建筑.中国人口众多，土地资源紧张，地震灾害严重，因此发展多层冷成型钢房屋建筑符合中国国情.将低层冷成型钢结构体系拓展至多层结构，存在4个主要技术难点.课题组通过结构体系与主要部件两个层面的改进，提出了多层冷成型钢龙骨式复合剪力墙结构体系及其两个重要部件——冷成型钢托梁龙骨-ALC板组合楼盖和带有夹心墙板单元的轻钢龙骨式复合墙体.还针对该新型体系的抗侧、抗火等基础理论问题，阐述了课题组研究进展及国内外同行的相关研究工作.最后，从宏观角度指出了该新型体系尚需开展的研究工作.</br>Cold-formed steel structures are natural green and industrialized buildings. Due to the large population, shortage of land resource, as well as serious earthquake disasters, the development of mid-rise cold-formed steel structure becomes very consistent with Chinese national conditions. At present, there are four major technical difficulties existed in the expansion of low-rise cold-formed steel structure systems to mid-rise buildings. Based on the investigation and improvement on the structure system and major components, a new mid-rise cold-formed steel framed composite shear wall structure system was proposed, and two important components of the new structure system were developed, including a composite floor system combining cold-formed steel joists with autoclaved lightweight concrete slabs and cold-formed steel shear wall with sandwich panel units. This paper also reviewed our and other researchers’ latest investigation on some fundamental theory problems, such as the lateral and fire resistances of the new structure system et al. Finally, the author points out some research work need to be conducted for the new structure system from a macroscopic perspective.
