ABSTRACT

at only these areas. There is concern that cOld-working or plastic deformation might deteriorate the toughness, the elongation and the buckling strength of RHS. These should however have the capacity for stable plastic defori.~ation when subjected to severe earthquake loadings. This paper investigates the strength, ductility and the ultimate behavior of cold formed RHSs to full scale.
