| 摘 要： | 对流－固砰击作用下两端铰支柱的弹－塑性动力屈曲进行了实验研究。通过分析铰支柱的弹－塑性响应规律，定义了柱的动力屈曲准则和动力塑性准则，井给出了相应的临界冲量值。同时，分析了不同长细比对铰支柱的弹－塑性动力屈曲性能的影响，考察了流－固砰击柱的与高速冲击和低速冲击所不同的动力屈曲特征。

| Abstract: | he elasto-plastic dynamic buckling of simply supported columns subjected to axial sol-id-fluid slamming is experimentally investigated. By analyzing the column response, two cri-teria, the dynamic buckling one and the dynamic plastic one are defined and relevant criticalimpulses are given. The effect of the slenderness of a column on the elasto-plastic dynamicbuckling behavior is discussed. The buckling characteristic of columns subjected to solid flu-id slamming different from those subjected to high speed impact and low speed impacts ex-amined. |
