摘　　要：引用国际上的最新试验结果,给出了冷弯薄壁非卷边槽钢承受集中荷载时腹板压屈荷载的一组计算公式,将计算结果与试验数据进行比较,建议的计算公式是简洁、合理的,且偏于安全。Based on the latest test on the cold-formed steel unlipped channels subjected to concentrated bearing load, one set of expressions is built up to attain the ultimate bearing capacity of cold-formed steel unlipped channel subjected to web crippling. The test results are compared with those obtained using the expressions. It is concluded that the suggested expressions are simple, rational and conservative.

关 键 词：冷弯薄壁非卷边槽钢 腹板压屈 极限承载力 试验研究
