| 摘 要： | 通过建立有侧移半刚接钢框架计算模型,推导出了有侧移半刚接钢框架柱考虑剪切变形影响的稳定方程和计算长度系数μ值的计算公式.通过与刚性连接钢框架计算结果进行对比,得出考虑剪切变形对柱计算长度系数有显著影响,二者最大相差29.22%.2层柱计算长度系数增大幅度较之其他2层要大,说明考虑剪切变形影响最显著的是第2层.

| Abstract: | Through the establishment of a semi-rigid steel frame computing model,a stabilits aquations of a lateral semi-rigid steel frame columns considering shear deformation effects and a formula for calculating the value ofμ. The length coifficient are derived with the rigid steel frame. Results obtained show shear deformation has a significant influence on the calculation of the length of the column, the biggest difference can be the 29.22%. The most significant influence of shear deformation is in the second storey. |
