用广义的有限条方法分析了多室箱梁的剪滞效应，推导了适用于分析剪滞效应的有限条单元刚度矩阵。最后，应用本文方法通过两个算例与文献１进行了比较。比较结果表明：该方法计算精度和效率较高，适用于分析多室箱粱的剪滞效应。
The shear lag effect of multi-chamber box girder is analyzed by the generalized finite strip method. The finite element stiffness matrix suitable for analyzing shear lag effect is derived. Finally, two examples are compared with literature 1 using this method. The comparison results show that this method has higher accuracy and efficiency and is suitable for analyzing the shear lag effect of multi-chamber box girders.
