To explore the application of environmental protection material-paper straw board in cold-formed thin-walled steel (CFS) structures and further develop the sheathing system, an innovative CFS framing wall sheathed by paper straw board (CFSSB) is proposed. Eight CFSSB composite wall specimens and one CFS frame without sheathing were tested under monotonic and reversed cyclic horizontal loads to study the shear performance of the CFSSB composite wall. Also, the shear performance of the wall specimens can be obtained. The key parameters include the value of the vertical load and the form of the CFS frame in this experimental program. By analyzing the specimen’s failure forms and failure process, the characteristic values of the bearing capacity, lateral stiffness, ductility coefficient and energy dissipation coefficient are obtained. The results show that the existence of paper straw board and adding diagonal braces to the CFS frame can significantly improve the shear capacity of CFSSB composite walls. The favorable seismic performance of the CFSSB composite wall was demonstrated in the experiment. In addition, a finite element model for CFSSB composite wall is developed using the software package ANSYS. The finite element analysis (FEA) results show a good agreement with the experiment results in terms of failure modes and skeleton curves, which verify the feasibility of the FEA model. Furthermore, extensive parametric analysis was carried out to analyze the factors affecting the shear capacity of the CFSSB composite wall. The FEA results show that the spacing of studs and self-tapping screws greatly influences the shear capacity of walls. Moreover, based on the failure of the screw connections, a formula for calculating the shear capacity of the CFSSB composite wall is proposed. The results of the formula calculation show good agreement with the experiment and FEA results, and it can provide a reference for engineering design.

为探索环保材料-纸秸秆板在冷弯薄壁钢（CFS）结构中的应用，进一步发展护套系统，提出了一种创新的纸秸秆板（CFSSB）护套CFS框架墙。8 个 CFSSB 复合墙体试件和 1 个无护套的 CFS 框架在单调和反向循环水平荷载下进行测试，以研究 CFSSB 复合墙体的剪切性能。此外，还可以获得壁试样的剪切性能。本实验方案中的关键参数包括垂直荷载值和 CFS 框架的形式。通过分析试件的破坏形式和破坏过程，得到了试件承载力、侧向刚度、延性系数和耗能系数的特征值。结果表明，纸吸管板的存在以及在CFS框架上增加斜撑可以显着提高CFSSB复合墙体的抗剪承载力。实验证明了 CFSSB 复合墙体良好的抗震性能。此外，使用软件包ANSYS 开发了CFSSB 组合墙的有限元模型。有限元分析（FEA）结果在失效模式和骨架曲线方面与实验结果吻合较好，验证了有限元分析模型的可行性。此外，还进行了广泛的参数分析，以分析影响 CFSSB 复合墙抗剪能力的因素。有限元分析结果表明，螺柱和自攻螺钉的间距对墙体的抗剪承载力有很大影响。而且，基于螺纹连接失效，提出了CFSSB复合墙体抗剪承载力计算公式。公式计算结果与实验和有限元分析结果吻合较好，可为工程设计提供参考。
