| 摘 要： | 首先利用变分法推导出变截面箱梁剪力滞效应微分方程并得出不同荷载作用下剪力滞系数的计算公式.采用Civil/Midas软件对某连续刚构箱梁进行了空间有限元计算,针对两种不同荷载作用形式分析了变截面箱梁剪力滞效应的规律.

| Abstract: | Differential equation of shear lag effect of box girder with varying depth is deduced according to differential method and the calculation formula of shear lag coefficient under the different loads is developed.Using the Civil/Midas software,finite element calcute is made to the continuous box girder.Aiming at two different load style,the role of shear lag effect of box girder with varying depth is illustrated. |
