| 摘 要： | 通过选取满足轴向应力自平衡条件的翼缘板剪滞翘曲位移模式，推导了宽翼缘T梁的应力计算公式，根据有效宽度的定义，进一步导出了有效宽度的理论计算公式．给出了一个宽翼缘T梁算例，计算表明，由本文所得出的计算公式算出的有效宽度更接近用ANSYS算出的结果．

| Abstract: | The formula of stress for wide flange T-beam is deduced by adopting the displacement pattern of shear lag warping whose axial stress reaches to an equilibrium condition,and the theoretical calculation formula is further deduced based on the definition of effective width.An example of wide flange T-beam is presented by the formula to get a conclusion that effective width computed by the calculation formula deduced in this thesis is close to the results computed by ANSYS. |
