| 摘 要： | 分析了结构失稳时P～δ试验曲线的图形性质;提出了以最大曲率推算结构失稳临界荷载;并导出了相应的计算公式。压杆和刚架弹性稳定试验的实测数据说明本文所述方法既精确又简便。特别是结构或模型不允许作破坏试验时,可直接推算失稳临界荷载。

| Abstract: | The characteristics of P-δ testing curre of buckling structures are analysed. A method of deducing the buckling load of structure by means of the concept of maximum curvature is presented and the correspondent calculating formula is established. The method is proved to be both accurate and simple by comparing the theoretical values with the experimentally measured values of the elastic stability tests of struts and frames. Especially, the buckling loads can be directly calculated with the formula when the structures and models are not admitted to do failure experiment. |
