摘要
根据双索面斜拉桥的受力特点，提出用余能原理和叠加法分析槽型宽翼压弯构件剪力滞效应的一般方法，推导了翼板截面应力分布公式，给出了计算示例．计算结果与文献［４］中的实验数据和数值解的对比分析表明，提出的分析方法是合理有效的．
In this paper,the theoretical model is presented to analyze the shear lag in wide-flange beam subjected to both axial and lateral loads. Based on the principles of residual energy and superposition, the formulae describing normal stress distribution in the wide-flange plate are derived. The feasibility of the theoretical method presented is demonstrated by comparing the calculated values with the results of model experiment and finite strip method.
