Abstract
Because of their excellent characteristics against wind and fluid loading and because of their appearance, steel tubular members are frequently used in a variety of structures including offshore oil drilling platforms, bridge piers and so on. There exist large discrepancies among currently available design recommendations for the design of such members against local buckling. This is mainly due to the wide scatter of experimental data. This paper is to present a series of carefully conducted failure tests on fabricated short cylindrical tubes in compression and in bending. Based on the test results, a design formula is proposed for local buckling strength of cylindrical pipes. Furthermore, a study on the interaction strength between local and overall buckling is also presented
