It was also found that the strength of FF specimen is close to the sumation of the strengths of FC and FS specimens with the same board thickness and screw spacing as FF specimen. As compared the test results with the research findings from Li [2]and Luo [3], It can be concluded that the failure mode of specimen is affected by both the sheathing thickness and the stud thickness. Different from this study, the failure mode of Li's test specimens is torsional-flexural buckling for most cases. The predicted values computed based on the AISI Specification seem to be conservative as compared to the tested values of FF specimens. Therefore, it is suggested that the effective length factor, K, can be taken as 0.5 to determine the wall stud assembly strength.

在三种不同试体组合分析时也发现，具外覆材支撑之立柱与外覆材受压内含支撑之立柱，两者之破坏强度相加，约等於具外覆材之墙体之破坏强度；试验结果与李岱真、罗浩之研究比较后，发现不同厚度之立柱与不同厚度之矽酸钙板之间束制关系明显影响强度之差异，且李岱真之试体破坏模式多为整体扭转-挠曲挫屈破坏，与本研究有较大差异；对於具外覆材之墙体与AISI预测值比较后，AISI规范预测值较保守，因此本研究有效长度系数建议采用0.5。
