摘要
由于箱梁结构广泛应用于桥梁建设中,而传统的受力分析方法存有较大的误差。采用实体退化板壳单元对杭州复兴立交桥这种单箱多室箱梁的结构进行空间分析,得出的应力和挠度与试验结果相符,证明了实体退化板壳单元的正确性和有效性。
For box girder structure which is applied extensively in bridge construction,the traditional analysis method of load is of comparatively bigger error.In the spacial analysis on Hangzhou Fuxing Grade Separation of which the structure is of box girder with single-box multi-cell,the application of solid degenerate plate/shell element is proved to be correct and effective for its conformability on stress and deflection with the testing results.
