摘　　要：根据我国人多地少的基本国情,将节能环保、工业化程度高的冷成型钢结构从低层房屋发展到多层住宅具有重要意义.传统的低层冷成型钢结构体系应用到多层结构中,将面临结构防火、结构竖向承载和多层结构抗侧等诸多技术难点.文中从足尺试验、数值模拟和理论简化计算方法三个方面对冷成型钢结构体系的主要承重和抗侧部件——冷成型钢组合墙体的抗剪性能研究进展进行全面阐述,深入剖析将低层冷成型钢结构体系拓展至多层结构所面临的主要抗侧问题,并从结构抗侧的角度提出将低层冷成型钢房屋拓展到多层住宅尚需开展的研究工作,以促进多层冷成型钢住宅在我国的推广应用.Cold-formed steel (CFS) structure has the advantages of energy conservation, environment protection and high degree of industrialization. Because of large population, the shortage of land resource, it is of great significance and more consistent with China′s national conditions to develop CFS structure from low-rise buildings to mid-rise dwellings. There are many technical difficulties in the expansion of low-rise CFS systems to mid-rise buildings, including fire resistance, vertical bearing capacity and the ability against lateral loads. In this study, the research progress on the shear performance of CFS shear walls, which are the main vertical and lateral load-bearing components of CFS structures, is comprehensively expounded from three aspects, including full-scale experiments, numerical simulation and theoretical simplified calculation method. The dominant anti-lateral problems for the expansion from low-rise CFS systems to mid-rise buildings are deeply revealed. Finally, in order to promote the application of mid-rise CFS dwellings in China, the authors point out the research work needed to be conducted of the expansion of low-rise CFS systems to mid-rise buildings, from the perspective of lateral performance of CFS structures.
