剪力滞效应研究的三杆比拟法

The three bar simulation analysis method of shear lag effect research

为了开展剪力滞实用计算方法的研究,在介绍求解剪力滞效应的三杆比拟法计算思路的基础上,将三杆比拟法应用于斜拉桥箱形主梁剪力滞效应的实用计算中,并通过与空间有限元计算结果的比较分析,指出了三杆比拟法在桥梁的初步设计阶段可以满足设计要求。

To develop the research of shear lag practical calculating method, and on base of introducing the calculating thought of solving the three bar simulation analysis method of shear lag effect, it uses the three bar simulation analysis method into the practical calculation of shear lag effect research of skew bridge boxed main beam, and through comparing with and analyzing the space finite element calculation effect, it points out that it can meet the need of design in the phase of the original design of the bridge of three bar simulation analysis method.
