建立了应用平面杆系有限元法计算程序分析连续弯箱梁桥的计算模型 ,并且还引入了应力增大系数来计入约束扭转产生的效应。本近似分析法可以给出较高精度的计算结果 ,因此 ,它对设计人员来说具有实用意义
The calculation model of continuous curved box girder bridge was established by using the finite element method of plane rod system. The stress augmentation coefficient was also introduced to account for the effect of constraint torsion. The approximate analysis method can give higher-precision calculation results, therefore, it is of practical significance to designers
