The result shows that the coped length, coped depth, and span length have a significant influence on the lateral-torsional buckling resistance of coped beam. In contrast, the yield strength, initial geometric imperfections have little effect on that.
分析结果表明：切口长度，切口高度，梁跨度对切口梁弯扭屈曲承载力折减颇大；而材料屈服强度，初始几何缺陷对其影响甚微。
