| 摘 要： | 通过对工字型钢-混凝土组合梁劁向失稳形式的理论分析，提出工字型组合梁稳定性分析的计算模型，并根据计算模型推导了组合梁负弯矩区受压下翼缘劁向屈曲的临界弯矩，然后通过与现行工字型组合梁的稳定理论和计算方法比较，确定了工字型组合梁负弯矩区稳定设计的修正方法和建议意见。

| Abstract: | Based on the theoretical annlysis of steel-concrete composite I -beams＇ lateral buckling, analytical model on the stability of compos-ire I -beams is put forward, and the formula which is used to calculate critical bending moraent in negative bending regioits is deduced. By comparison with other stability theories and methods, this dissertation indicates the design correction and suggestion about the stability of composite I -beams in negative bending regions. |

| Keywords: | composite beams critical moment bearing capacity of stability lateral-torsional buckling |
