| 中文摘要: |
| 研究钢 混凝土双面组合连续箱梁的徐变问题。根据混凝土徐变后的双面组合连续箱梁的截面应力自相平衡，内力仍为零这一条件，通过平衡方程得到负弯矩区截面的曲率，进而得到截面的应力计算公式；通过算例分析双面组合连续箱梁的应力重分布情况。 |
| 英文摘要: |
| This paper studies the creep problem of the double steel concrete composite continuous box girder. According to the balance of section stress and zero internal force, the stress distribution along the cross section at the positive and negative bending regions are derived under the long term load. Analysis is made of the stress redistribution through an example of double steel concrete composite continuous box beam. |
