| 摘 要： | 在钢-混凝土连续组合梁的负弯矩区,由于混凝土板受拉,使翼板容易开裂,造成耐久性下降。在大量调研的基础上,对组合梁负弯矩区混凝土翼板开裂的影响因素及开裂控制方法进行归纳和总结,对组合梁裂缝宽度的计算公式进行比较分析,可为组合梁负弯矩区开裂及控制方法研究提供理论依据。

| Abstract: | At the negative moment zone of the continuous composite beams,the concrete slab is easy to crack due to its low tension strength,so that the durability deceases.Based on a great deal of investigation,the crack influence factors and control measures are summarized,the crack width calculation methods of the steel-concrete composite beam are compared and analyzed,which give a theoretical foundation for the study of the concrete crack at the negative moment zone of the steel-concrete composite beams. |

| Keywords: | steel-concrete composite beam negative moment zone crack control method crack width |
