摘要
采用连续的悬臂梁模型,对弯曲型支撑-框架体系的弹性稳定进行研究,得出了体系有侧移失稳的临界荷载公式。在此基础上分析并提出了弯剪型支撑双重抗侧力体系的临界荷载公式,并与有限元方法结果进行对比,所得公式精度良好。提出的公式对工程实际应用具有参考意义。
It investigates the elastic stability of the frame-shearwall structure in a vertical column,and the critical load of dual systems is proposed.Then the formula is extended to the dual system of flexural——shear typed bracing.Comparison with the results of FEM shows a good correlation between them.The proposed formula can be used for designing in practice.
