| 摘 要： | 采用薄壁曲线箱梁剪力滞基本微分方程的齐次解作为曲箱梁单元的位移模式，利用刚度法与功能原理，分别导出了曲线箱梁进行有限段法分析的单元刚度矩阵和荷载列阵，编制了计算程序，对薄壁曲线箱梁的剪滞效应进行了计算，指出有限段法的精度可以满足实际工程的要求。 |
| 关 键 词： | 薄壁曲线箱梁 剪滞效应 有限段法 位移模式 |

| Abstract: | Using homogeneous solution of basic differential equation of thin-wall curved box-girder's shear lag as displacement pattern of curved box-girder unit,the author derives unit stiffness matrix and load matrix of curved box-girder to carry out finite segment analysis using stiffness method and functional principle,develops a calculation program,calculates shear lag effect of thin-wall curved box-girder,and points out that the accuracy of finite segment method can satisfy the demands of practical engineering. |
| Keywords: | thin-wall curved box-girder shear lag effect finite segment method displacement pattern |
