| 摘 要： | 运用编制的有限元程序对有侧向约束的框架梁端或连续梁端存在负弯矩的情况进行了计算模拟分析,绘出了K—φb曲线,进而得出了Kcr—h/t1曲线拟合公式,以此判断在上述情况下是否需要考虑梁端负弯矩的影响,防止整体失稳。

| Abstract: | The end of the beam with lateral restraint there is a negative moment a is calculated and analysed in the finite element program to arrive at the K—φb curve the Kcr—h/t1 formula.According to the Kcr—h/t1 formula,whether it needs to consider the impact of the negative moment,ensure the bearing capacity of stability. |

| Keywords: | beam the negative moment the overall stability compression flanges |
