摘要
主要介绍了利用叠加原理求解在双向板受力状态下的箱梁顶板的弯曲问题,简要介绍了基于能量变分原理的弹性薄板的求解,并结合工程实际问题,与有限元解答相比较,证明此方法在箱梁受力分析中具有很好的实用价值。
In this paper, the authors mainly introduced the solution to the bending of top plates of box (girder) under the mechanical state of the two-way plate by the superposition method and simply solved the issue of the elastic thin plate via energy variation principle. Then the two solutions were compared with those of (finite) element method through an engineering example. The results showed that the superposition method in the mechanical analysis of box girder was more applicable in pactice.
