✦ Synopsis

In this paper, a comprehensive series of tests is described and presented. The tests were performed to examine the behaviour of short thin-walled circular steel tubes with or without internal restraint. The tubes had diameterto-thickness ratios of between 55 and 200 and a length-to-diameter ratio of 3.5. The tests included bare steel tubes loaded both axially and at small eccentricities, and axially loaded steel tubes with an internal restraint medium. The material properties have been measured including residual stresses and geometric imperfections. The test strengths have been compared to strength models in design standards and specifications. Recommendations for design have been made.
