Cold-formed steel (CFS) framing shear walls has been widely used as the lateral force resisting system of light-weight steel structures. While the behaviors of walls have been numerically studied, there is a need to develop more convenient and efficient modeling strategies. In this paper, a simulation framework consisting of component-level to system-level analysis for the seismic evaluation of steel-sheathed CFS walls was proposed by using OpenSees software. Based on the improved fastener-based method, refined numerical models were developed and validated against tests of steel sheathed CFS shear walls. Self-drilling screw connection tests were conducted to characterize the nonlinear properties of the member-to-sheathing connections as inputs in the models. Then, a set of structural archetypes were systematically analyzed by nonlinear static and incremental dynamic analysis in accordance with FEMA P695. The results showed that the proposed simulation framework could well capture the response of CFS walls and evaluate the seismic performance of structural system. The post-peak behavior of wall had a significant impact on the collapse resistance of the structure. The seismic response modification coefficient value was suggested (R = 4.25) for the high-performance steel-sheathed CFS framing shear walls studied in this paper.

冷弯型钢（CFS）框架剪力墙已被广泛用作轻型钢结构的抗侧向力系统。虽然已经对墙壁的行为进行了数值研究，但需要开发更方便和有效的建模策略。在本文中，使用OpenSees软件提出了一种由构件级到系统级分析组成的钢护套CFS墙体抗震评估的仿真框架。基于改进的基于紧固件的方法，开发了精细的数值模型，并针对钢护套 CFS 剪力墙的试验进行了验证。进行自钻螺钉连接测试以表征作为模型输入的构件到护套连接的非线性特性。然后，根据 FEMA P695，通过非线性静态和增量动态分析系统地分析了一组结构原型。结果表明，所提出的仿真框架可以很好地捕捉 CFS 墙的响应并评估结构体系的抗震性能。墙体的峰后行为对结构的抗倒塌能力有显着影响。 本文研究的高性能钢壳CFS框架剪力墙建议采用地震反应修正系数值（ R =4.25）。
