| 摘 要： | 本文根据阶梯梁的Ｍ（ｘ）／ＥＩ（ｘ）图形特征，选定任意一个等直梁，其惯性矩假定为Ｉｃ，令该等直梁的〔Ｍ（ｘ）〕ｃ／ＥＩｃ与Ｍ（ｘ）／ＥＩ（ｘ）的图形完全相同，由此确定等直梁上的外力分布规律，最后计算等直梁弯曲变形来代替原阶梯梁。

| Abstract: | According to the M(x)EI(x) figure characteristic of stair beam,choosing any equivalent section straight beam on the assumption that the moment of inertia is I c,make it a condition that M(x) cEI c of the equivalent section straight beam be completely identical with M(x)EI(x) figure,thus the external force distribution rule of equivalent section straight beam is determined.Finally,calculating the bending and deformation of equivalent section straight beam substitutes as original stair beam. |
