摘要：

为了保证结构在遭受风荷载、地震等水平力作用时具有足够的承载能力，研究了不同截面冷弯薄壁型钢组合墙受剪性能。确定制备冷弯薄壁型钢组合墙各材料的基本参数，制备矩形截面、U型截面和Z型截面3种冷弯薄壁型钢组合墙试验样品，分别测试各个试验样品在加载的剪切荷载下的位移、裂缝变化，监测试验样品的极限荷载与破坏荷载，验证各个试验样品的承载力退化变化，分析螺钉间距、型钢厚度与间距对样品的抗剪性影响。试验结果显示：相比于另两种截面，Z型截面冷弯薄壁型钢组合墙受荷载影响位移变化最小，裂缝出现较短；当螺钉间距为150 mm、型钢厚度为50 mm、立柱间距为60 mm时，组合墙的受剪性能最佳。

Abstract:

In order to ensure that the structure has sufficient bearing capacity under horizontal forces such as wind loads and earthquakes， the shear performance of cold-formed thin-walled steel composite walls with different cross-sections is studied. Determine the basic parameters of materials for preparing cold-formed thin-walled steel composite walls， prepare three types of cold-formed thin-walled steel composite wall test samples： rectangular section， U-shaped section， and Z-section. Test the displacement and crack changes of each test sample under the loaded shear load， monitor the ultimate load and failure load of the test sample， verify the degradation changes of the bearing capacity of each test sample， and analyze the influence of screw spacing， steel thickness， and spacing on the shear resistance of the sample. The experimental results show that compared to the other two types of sections， the Z-shaped section cold-formed thin-walled steel composite wall has the smallest displacement change under load and shorter crack occurrence. When the screw spacing is 150 mm， the steel thickness is 50 mm， and the spacing is 60 mm， the shear performance of the composite wall is optimal.

Key words: cold-formed thin-wall steel, composite wall, shear performance, U-shaped section, Z-section, rectangular section
