Local buckling and deformation capacity of tubes in steel structures

Abstract

In this paper, the focus is on local buckling limits after yielding of the cross section (plastic buckling). This is in contrast to thin cylindrical shells, where local buckling occurs at stresses below the yield stress (elastic buckling-the main focus of ECCS TWG 8.4). A survey of available test results and differences in various design standards is given. Reasons for the scatter found in experiments are identified. There is a need for more harmonisation in design standards, focusing on the practical needs for each application. © 2008 Taylor & Francis Group, London.
