摘　　要：提出用两块曲板、简易的夹具及普通万能试验机来进行半径Ｒ≥１０００ｍｍ的圆柱壳剪切屈曲实验．解决了使用单块曲板实验剪流合力不易通过剪力中心的难题．也避免了使用薄壁圆筒或封闭筒体扭转方案的一些缺点．实验结果与有限元计算分析以及国外成熟结果比较，符合良好．This paper provides a new shear buckling experimental method of cylindric shell of R ≥ 1000 mm which uses two curved plates and can perform in ordinary test machine. So the difficult problem of the resultant of shearing folw loading to curved plate when testing by single curved one, which is not easy to pass through the shearing center,has been solved. It,also avoids the defects caused by torsion on thin cylinder of closed tube. The testing results meet very well with the finite element computational analysis and the published works.
