| 摘 要： | 该文运用有限元方法,对60座不同截面的桥梁模型进行有限元分析,得出了每一座连续梁模型的最大正弯矩、最大负弯矩、梁端支座附近剪力及中间墩支座附近剪力分配系数。通过多元线性回归分析,得出了每一分配系数与车道数、跨度及箱体个数等主要参数的关系,即内力分配系数经验公式,可供设计参考。

| Abstract: | The article carries out the finite element analysis of 60 bridge modules with the different sections by applying the finite element method, and gives the maximum positive moment, the maximum negative moment, the shearing force near the support at the end of beam and the shearing distribution coefficient near the support at the intermediate pier of each continuous beam module. Through the multi-element linear regression analysis, the article gives the relation of each distribution coefficient with the main coefficients of lane number, span and box number, that is, the inner force distribution coefficient experience formula, which can be referred for the design. |
