摘要
针对用能量变分法求解箱梁剪力滞的问题，推导了假设纵向位移函数为m次抛物线时的剪、力滞微分方程，并通过实例探讨了m的取值。
Aiming at the, problem of energy variational method solves the problem of Shear lag effect; the article deduced the shear lag differential equation In the case of portrait displacement function is m-degree parabola, and dlscussed the value of m by example.
