· A reason leading to improvement of the mean crushing load is that formation of plastic hinges in this type of tubes is much more difficult than in simple ones, and calls for a higher axial load. Moreover, in a section of the tube where plastic hinges occur, the corrugated wall of the tube should be flattened, and this flattening needs energy.
