This paper describes a test program on austenitic stainless steel beam-columns. Two types
of section were investigated: cold-formed square hollow section and welded H section.
Twelve material tensile coupon tests and four stub column tests were conducted to provide
the material properties of the specimens. The overall initial geometric imperfections were
measured. Ten beam-columns were tested between pin-ended conditions with sideway
supports. Results from the tests, including the strengths, the load-deformation responses …
