中文摘要：

研究了一种新型钢-混凝土组合墙体，即冷弯薄壁型钢增强的混凝土剪力墙的抗剪性能。通过5个冷弯薄壁型钢混凝土剪力墙和1个钢筋混凝土剪力墙的拟静力试验，研究了边缘构件纵筋类型及数量、表面钢模网、冷弯薄壁型钢底部锚固等构造措施对剪力墙抗剪性能的影响。研究表明：配筋合适的冷弯薄壁型钢混凝土剪力墙的受剪性能和破坏模式与传统钢筋混凝土剪力墙不同，从开始受力到破坏经历了整截面墙到分缝剪力墙的演变过程，具有很好的延性和变形能力；表面配置钢模网可提高墙体承载力，但会降低延性和极限变形能力；冷弯薄壁型钢锚固于基础中可保持后期承载力的稳定；适当增加边缘构件的纵筋量可提高墙体的变形能力。基于试验研究，建议了冷弯薄壁型钢混凝土剪力墙的合理构造措施。

英文摘要：

An innovated steel-concrete composite structural wall, CTSRC （Cold-formed Thin-walled Steel Reinforced Concrete） shear wall, is presented. Five CTSRC shear walls and one steel bars reinforced concrete （RC） shear wall are tested quasi-statically under low cyclic lateral loads for shear performance, and the effects of longitudinal reinforcement in the edge member, the anchorage of the cold-formed thin-walled steel, and the steel meshes are investigated. The test results show that CTSRC shear walls have adequate ductility and deformability in view of their failure process from integral wall to slit wall, which is different to that of RC walls. The study proves that the steel meshes increase the wall＇s bearing capacity, but impair its ductility and deformability. It can be found that anchoring steel profiles into the basement makes the later bearing capacity stable, and that the wall＇s behavior is improved with the increase of longitudinal reinforcement in the edge member. Based on above observations, the reasonable configurations of the details of CTSRC shear walls are suggested for actual applications.
