摘要
应用能量变分法证明了在均布面荷载作用下,在弹性变形范围内简支箱梁顶板恒出现负剪力滞,并给出了顶板弯曲法向应力的计算公式。
Energy variational method is applied in ＂this paper proves that under the uniform - distributed plane load, within the scope of the elastic deformation, the top plates of simply supported box beams permanently exist negative shear lag, and gives the formula of bending normal stress of the top plates.
