The Behaviour of Circular Tubes with Large Openings Subjected to Axial Compression
Circular, thin-walled, steel tubes, with elongated, non-axisymmetric openings subjected to compressive, longitudinal load are examined. Thirteen laboratory tests are described in which careful measurements were made of displacements and strains. The tested specimens were in two geometrically dissimilar groups and their modes of failure were found to be different; in one group the free edges of the openings buckled before failure of the tube and in the other group large displacements at the free edges coincided with the reducing axial stiffness of the tubes.Two theories are proposed to explain these different kinds of behaviour and their predictions compared with the experimental results.
