| 本文利用凝聚矩阵求隔板与箱联结点赘余力,进而分析带柔性隔板的曲线连续箱梁及其隔板的内力,并对刚、柔性隔板与无隔板多跨曲箱梁以及直条法与曲条法进行分析比较,表明本文计算结果是令人满意的,从中得到有关结论。 |
| 英文摘要: |
| The continuous curved box girder with column-support and without diaphragms is studied in document [3]. In this paper, the redundent forces of restraining point on diaphragms and box girder are determined by condensable matrix so that the internal forces of continuous curved box girder and its transverse diaphragms are obtained. These extended the area of the analysis in document [3]. The multi-span continuous box girder with rigid and flexible transverse diaphragms are calculated and comparison between the two are made. In the meanwhile, the above calculating results are compared with the analysis of box girder without transverse diaphragms and the straight finite strip method. Comparing results shows that the calculations in this paper are quite satisfactory. |
