摘要
提出了具有一对弹簧支承的计算模型,用来计算连续箱梁桥的内力增大系数.用本模型所得到的一个算例的分析结果与按传统方法的分析值吻合甚好,并且它比后者在计算过程上得到了一定程度的简化.
To calculate the increasing coefficient of internal forces for continuous box girder bridges the calculating model with two spring bearings is established. The analytical results of an example by this model coincided satisfactory with those by the traditional method, and it simplified the calculation process to a certain extent with the latter.
