The results showed that the bucklingconfiguration was helical curve for the gravitational tubular under the axial compressive force and torque.
结果表明，受压扭组合作用的有重管柱的屈曲构型为上疏下密的螺旋曲线。

On this basis, the influences of corrugation configuration, the overall dimensions and steel thickness of corrugated webs to ultimate shear bucking load and buckling mode are investigated.
