摘要
本文解析推导出计算冷弯型钢棱角部分屈服强度的两个公式,进而推导出简便实用的全截面屈服强度及设计强度的计算公式,能较好地满足工程应用的需要,适用于厚、薄壁冷弯型钢以及不同的内曲率半径厚度比(a/t)的棱角和不同的成型方法。
In this paper two theoretical formulas for calculating the corner yield strength of cold formed steel have been first analytically derived. Then the simplified and practical equations for predicting the yield strength of full section and design strength in consideration of the effect of strain hardening of cold formed steel have been derived. These equations are simple, clear, and suitable for engineering purpose. They are applicable to either thin or thick wall sections with corners of different a/t ratios and differentforming processes.
