| 摘 要： | 运用逐段分析的方法,并结合转角-位移法基本方程的推导,建立了考虑剪切变形影响的带悬伸段柱的稳定方程.对比分析了有关文献给出的轴力作用在柱顶且不考虑剪切变形影响的相关计算长度系数的拟合公式,给出了各公式拟合的计算长度系数用来求临界荷载时造成的误差;指出了柱脚铰接和刚接时临界荷载差值的关系;给出了轴压力对转角约束刚度的影响分析.以上分析结论对工程设计有一定的使用价值. |
| 关 键 词： | 稳定方程 计算长度系数 铰接 刚接 抗弯刚度 |

| Abstract: | By means of the deduction of the slope-deflection and the analysis of each part of the column,the stability equation is established considering the shear deformation in this paper.The paper also analyzes and compares the formula of the effective length factors with load in the upper and devoid of shear deformation.It also points out the precious influence on the critical loads caused in each formula,moreover,compares the critical loads of the base-fixed overhanging column with the base-hinged overhanging co... |
