以６４根单面螺栓连接的等边单角钢压杆稳定试验资料为主要依据，结合国内外钢结构规范和有关技术规定中计算其压杆承载力的计算结果，运用最小二乘法数据统计原理，推导出等边单角钢压杆稳定性的简便验算方法。
Based on the stability test data of 64 single-sided equilateral single-angle bars with single-sided bolted connection, the calculation results of the bearing capacity of bar under the steel structure specifications and related technical regulations at home and abroad are combined. Based on the statistical principle of least- A simple method to check the stability of equal angle single angle bar is deduced.
